Description

Technical Field

[0001] The present application relates to the technical field of hydrocarbon analysis equipment, and in particular to a hydrocarbon analysis system. Background Art

[0002] In today's energy, chemical industry, environmental protection and scientific research, accurate and efficient analysis of hydrocarbons is crucial. As one of the most important organic substances in nature, hydrocarbons not only exist in fossil fuels such as oil and natural gas, but are also the basic building blocks of many industrial products and chemicals. In view of its key role in energy utilization, environmental protection, product quality control and safe production, quantitative analysis of hydrocarbons is particularly urgent. Especially in situations such as the safe operation of air separation equipment, environmental pollution emission monitoring, and refining and chemical process control, real-time and accurate determination of hydrocarbon content is not only the basis for meeting regulatory requirements, but also an important means to ensure process stability, improve economic benefits and prevent potential accidents.

[0003] Most of the hydrocarbon analysis systems in the existing technology use hydrogen flame ionization detectors (FIDs). Their unique detection principle and excellent performance play an important role in the field of hydrocarbon analysis. Their working principle is to use hydrogen and hydrocarbons in the sample to form a stable hydrogen flame in an oxygen environment. The sample decomposes in the high-temperature flame to produce ions, and then the changes in electrical signals are collected by electrodes to quantitatively determine the hydrocarbon content. Compared with other detection technologies, hydrogen flame ionization detectors (FIDs) have extremely high sensitivity and linear response range, and can effectively cope with hydrocarbon analysis tasks in various complex matrices. At the same time, they have good stability and reproducibility, ensuring the reliability and accuracy of the analysis results.

[0004] However, a key factor for the efficient operation of a hydrogen flame ionization detector (FID) is a continuous supply of hydrogen. In practical applications, once the hydrogen supply becomes unstable and the hydrogen flame cannot be maintained continuously, the hydrogen flame ionization detector will be flamed out, seriously affecting the continuity and accuracy of hydrocarbon analysis. Flameout not only interrupts the normal analysis process, but also may cause damage to the internal components of the detector, increasing maintenance costs. In addition, due to the interruption of measurement caused by flameout, the capture of important parameter changes may be missed, delaying decision-making, and causing adverse consequences for production process control and environmental monitoring. Therefore, how to give operators time to complete the replenishment of hydrogen when the hydrogen is exhausted has become a problem that must be solved to improve and perfect the hydrocarbon analysis system.

[0037] The exemplary embodiments disclosed in the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments disclosed in the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0038] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0039] Reference Figure 1 As shown, in the embodiment of the present application, a hydrocarbon analysis system is proposed, which may include: an analysis device 1, used to measure the hydrocarbon concentration in the gas; a gas source mechanism, used to store the gas medium to be measured by the analysis device 1; a conveying mechanism, which is connected with the gas source mechanism and the analysis device 1, and is used to output the gas medium in the gas source mechanism to the analysis device 1; the conveying mechanism includes: an air pipeline 4 and a hydrogen pipeline 5, which are used to output a hydrogen-oxygen mixed gas of a target ratio to the analysis device 1; the hydrogen pipeline 5 includes a detection receiving section 5a, an abnormality processing section 5b and a hydrogen output section 5c; the detection receiving section 5a is connected to the gas source mechanism, and is equipped with a pressure sensing unit 51 to detect the hydrogen pressure received by the gas source mechanism; the abnormality processing section 5b is connected between the detection receiving section 5a and the hydrogen output section 5c, and is connected to the analysis device 1 through the hydrogen output section 5c, and the abnormality processing section 5b is equipped with an abnormality processing unit 52 connected to the signal of the pressure sensing unit 51;

[0040] The abnormality processing unit 52 has a storage function formed by cutting off the connection between the abnormality processing section 5b and the detection receiving section 5a, and can control the flow rate of hydrogen delivered from the abnormality processing section 5b to the hydrogen output section 5c.

[0041] Specifically, in the technical solution adopted by the present application, the analysis device 1 can adopt a hydrogen flame ionization detector (FID) capable of detecting the carbon and hydrogen concentration of the gas, and the gas source mechanism can supply the sample gas medium, the standard gas medium, the hydrogen medium and even the air medium containing some oxygen content to the analysis device 1 respectively; the conveying mechanism safely conveys each gas medium from the gas source mechanism to the analysis device 1, so that the analysis device 1 can detect the compounds containing carbon and hydrogen formed by the mixture of the above-mentioned gas media. The conveying mechanism includes at least an air pipeline 4 and a hydrogen pipeline 5, so as to provide the required proportion of hydrogen-oxygen mixed gas to the analysis equipment 1. The technical point of the present application is that the hydrogen pipeline 5 is divided into a detection receiving section 5a, an abnormal processing section 5b and a hydrogen output section 5c through a pressure sensing unit 51 and an abnormal processing unit 52. The part of the conveying section on the hydrogen pipeline 5 where the pressure sensing unit 51 is arranged is the detection receiving section 5a, which is connected between the air source mechanism and the abnormal processing section 5b. The pressure sensing unit 51 can be used to detect the pressure to determine the amount of hydrogen discharged from the air source mechanism to know whether the hydrogen reserve in the air source mechanism is sufficient. The hydrogen output section 5c is connected between the abnormal processing section 5b and the analysis equipment 1, and is used to convey the hydrogen medium in the abnormal processing section 5b to the analysis equipment 1. When in use, if the pressure sensing unit 51 detects that the pressure of the hydrogen medium supplied by the gas source mechanism to the hydrogen pipeline 5 is reduced and the pressure of the hydrogen medium cannot be adjusted to the normal threshold, it indicates that the hydrogen reserve in the gas source mechanism is about to be exhausted, and a warning that can be perceived by the operator is issued through the pressure sensing unit 51, and an emergency control signal is sent to the abnormal processing unit 52 at the same time, so that the hydrogen pipeline 5 enters an emergency state, and the hydrogen pipeline 5 in the emergency state starts the normal processing unit to close the channel connecting the detection receiving section 5a and the abnormal processing section 5b, and urgently reduces the pressure and flow rate of hydrogen delivered by the abnormal processing section 5b to the hydrogen output section 5c, so as to effectively store the hydrogen medium in the abnormal processing section 5b, and the hydrogen and air mixed gas formed by the hydrogen delivered to the analysis device 1 through the hydrogen output section 5c can maintain the analysis device 1 to operate at the minimum requirement. In this way, the time difference that can be operated is delayed for the gas source mechanism to replenish the hydrogen medium, and the analysis device 1 is effectively prevented from directly shutting down and stopping operation when the hydrogen medium in the gas source device is about to be exhausted, causing unnecessary trouble.

[0042] Further, see Figure 1 As shown, in some embodiments, the pressure sensing unit 51 includes: a hydrogen pressure detection component 511, which is configured in the detection receiving section 5a and is used to detect the hydrogen pressure in the detection receiving section 5a in real time; a signal sending component 512, which is integrated on the hydrogen pressure detection component 511 and is used to send abnormal pressure information in the detection receiving section 5a to the abnormal processing unit 52.

[0043] Specifically, in the technical solution adopted by the present application, in one embodiment, the pressure sensing unit 51 may include a hydrogen pressure detection component 511 and a signal sending component 512. The hydrogen pressure detection component 511 extends its detection end to the hydrogen pressure detection component 511 inside the detection receiving section 5a, so as to be able to detect the hydrogen pressure delivered to the detection receiving section 5a by the gas source mechanism. The signal sending component 512 can collect the pressure change signal detected by the hydrogen pressure detection component 511 to indicate that the pressure signal has changed. In this embodiment, the collected changed pressure signal can be sent to the abnormal processing unit 52 through the central processing unit or the programmable logic device (PLD), so that the abnormal processing section 5b enters an emergency state under the influence of the abnormal processing unit 52.

[0044] Further, see Figure 1 As shown, in some embodiments, the abnormality handling unit 52 includes: an emergency shut-off valve component 521, which is arranged on the air inlet end of the abnormality handling section 5b and is connected to the signal sending component 512 for signaling, and is used to close the connection channel between the abnormality handling section 5b and the detection receiving section 5a; an output control component, which is arranged on the air outlet end of the abnormality handling section 5b and is connected to the signal sending component 512 for signaling; the output control component includes a hydrogen pressure reducing valve component 522 and a hydrogen pressure detection gauge 523 and a hydrogen flow detection gauge 524 located at the hydrogen pressure reducing valve component 522 near the air outlet end of the abnormality handling section 5b, and the hydrogen pressure reducing valve component 522 adjusts the pressure of hydrogen output from the abnormality handling section 5b to the hydrogen output section 5c through the pressure information and flow information obtained by the hydrogen pressure detection gauge 523 and the hydrogen flow detection gauge 524.

[0045] Specifically, in the technical solution adopted by the present application, in one embodiment, part of the pipeline in the abnormal processing section 5b is used as a space for storing hydrogen, and in this embodiment, the space for storing hydrogen is located between the emergency stop valve 521 and the hydrogen pressure reducing valve 522. After receiving the control signal sent by the signal sending component 512, the emergency stop valve 521 closes the connection channel between the abnormal processing section 5b and the detection receiving section 5a. At the same time, the hydrogen pressure reducing valve 522 also reduces the flow rate of hydrogen output from the abnormal processing section 5b to the hydrogen output section 5c through the control signal. At this time, the hydrogen flow rate is based on the ability of the analysis device 1 to operate at the minimum requirement. In this embodiment, a hydrogen pressure detection meter 523 and a hydrogen flow detection meter 524 for detecting the pressure and flow of the abnormal processing section 5b can be set in the direction of the gas outlet end of the hydrogen pressure reducing valve 522 close to the abnormal processing section 5b, so as to obtain the target threshold value required to be adjusted by the hydrogen pressure reducing valve 522 in an emergency state. In this embodiment, the abnormal processing section 5b can be scientifically and accurately controlled to supply the hydrogen output section 5c with the hydrogen required by the analysis equipment 1 to operate at the minimum requirements. This not only enables the analysis equipment 1 to operate stably, but also effectively extends the time for operators to replenish hydrogen to the gas source equipment.

[0046] Further, see Figure 1 As shown, in some embodiments, an air pressure regulating unit 41 is also included, which is configured on the air pipeline 4; the air pressure regulating unit 41 includes an air pressure reducing valve component 411 and an air pressure detection gauge 412 located at the air pressure reducing valve component 411 close to the air outlet end of the air pipeline 4; the air pressure reducing valve component 411 is signal-connected to the signal sending component 512, and is used to adjust the air pressure delivered by the air pipeline 4 to the analysis device 1.

[0047] Specifically, in the technical solution adopted by the present application, in one embodiment, the air pipeline 4 can be connected to the air storage tank (not shown in the figure) in the air source mechanism, and can also directly use the air in the external space to supply the air medium containing oxygen to the analysis device 1. In this embodiment, the air pipeline 4 is also equipped with an air pressure regulating unit 41, which controls the pressure of the air medium supplied by the air pipeline 4 to the analysis device 1 through the flow rate of the hydrogen medium supplied to the analysis device 1 by the hydrogen pipeline 5, so as to adjust the flow rate of the air medium delivered to the analysis device 1 by the air pipeline 4. In order to realize pressure regulation on the air pipeline 4, the air pressure regulating unit 41 includes an air pressure reducing valve 411 connected to the signal sending component 512, and an air pressure detection meter 412 located at the air pressure reducing valve 411 near the air outlet end of the air pipeline 4, and the air pressure detection meter 412 is used to detect the air pressure after being adjusted by the air pressure reducing valve 411.

[0048] When in use, the target ratio of hydrogen-oxygen mixture is interpreted as follows: when the hydrogen pipeline 5 is in a normal state, the hydrogen pressure delivered by the hydrogen pipeline 5 to the analysis equipment 1 is a normal threshold value. At this time, the ratio of the pressure of the air delivered by the air pipeline 4 to the analysis equipment 1 to the normal threshold value of the hydrogen pressure can be adjusted to 2.5:1; and when the hydrogen pipeline 5 is in an emergency state, the hydrogen pressure delivered by the hydrogen pipeline 5 to the analysis equipment 1 is an abnormal emergency threshold value. At this time, the ratio of the pressure of the air delivered by the air pipeline 4 to the analysis equipment 1 to the abnormal emergency threshold value of the hydrogen pressure can be adjusted to 2:1.

[0049] Further, see Figure 1 As shown, in some embodiments, the delivery mechanism further includes: a sample gas pipeline 2 , which is connected to the gas source mechanism and is used to deliver the sample gas medium to the analysis device 1 .

[0050] In one embodiment, the sample gas pipeline 2 is provided with a sample gas stop valve 21 for controlling the opening and closing of the sample gas pipeline 2, a sample gas discharge valve 22 for discharging residual gas in the sample gas pipeline 2, a sample gas one-way valve 23 for limiting the flow direction of gas in the sample gas pipeline 2, and a sample gas flow detection meter 24 for detecting the flow rate of sample gas output from the sample gas pipeline 2 to the analysis equipment 1; the sample gas discharge valve 22 is arranged between the sample gas stop valve 21 and the sample gas one-way valve 23, the sample gas stop valve 21 is located on a side of the sample gas discharge valve 22 close to the gas source mechanism, and the sample gas one-way valve 23 is located on a side of the sample gas discharge valve 22 close to the analysis equipment 1; the sample gas flow detection meter 24 is located on a side of the sample gas one-way valve 23 close to the analysis equipment 1.

[0051] Specifically, in the technical solution adopted by the present application, the sample gas stop valve 21 may include a first sample gas stop valve and a second sample gas stop valve. In the embodiment, the first sample gas stop valve is arranged on the gas inlet end of the sample gas pipeline 2 close to the gas mechanism, and is used to control the opening and closing between the sample gas pipeline 2 and the gas source mechanism; the second sample gas stop valve is arranged at a position close to the gas outlet end of the sample gas pipeline 2, specifically between the sample gas discharge valve 22 and the first sample gas stop valve. When the sample gas pipeline 2 is closed by the second sample gas stop valve, a partial pipe section capable of discharging residual sample gas through the sample gas discharge valve 22 can be formed between the second sample gas stop valve and the gas outlet end of the sample gas pipeline 2. When in use, the second sample gas stop valve can be closed, and the sample gas in the partial pipe section can be emptied through the sample gas discharge valve 22, so that the sample gas pipeline 2 can be safely disconnected from the analysis device 1, so that the analysis device 1 or the sample gas pipeline 2 can be inspected and repaired. A sample gas one-way valve 23 and a sample gas flow meter 24 are also provided on the sample gas pipeline 2. The sample gas one-way valve 23 can limit the flow direction of the sample gas in the sample gas pipeline 2 to flow from the gas source mechanism to the analysis device 1, effectively avoiding the backflow of the sample gas medium. The sample gas flow meter 24 is used to detect the flow rate of the sample gas medium delivered from the sample gas pipeline 2 to the analysis device 1 for adjustment.

[0052] Further, see Figure 1 As shown, in some embodiments, the delivery mechanism further includes: a calibration pipeline 3 , which is connected to the gas source mechanism and is used to deliver standard gas to the analysis device 1 .

[0053] In one embodiment, the calibration pipeline 3 is provided with a standard gas shut-off valve component 31 for controlling the opening and closing of the calibration pipeline 3, a standard gas exhaust valve component 32 for exhausting residual gas in the calibration pipeline 3, and a standard gas one-way valve component 33 for limiting the flow direction of gas in the calibration pipeline 3; the standard gas exhaust valve component 32 is arranged between the standard gas shut-off valve component 31 and the standard gas one-way valve component 33, the standard gas shut-off valve component 31 is located on the side of the standard gas exhaust valve component 32 close to the gas source mechanism, and the standard gas one-way valve component 33 is located on the side of the standard gas exhaust valve component 32 close to the analysis equipment 1.

[0054] Specifically, in the technical solution adopted by the present application, the calibration pipeline 3 is used to deliver standard gas to the analysis device 1 through the gas source mechanism. The standard gas is a gas with a fixed carbon and hydrogen content, which is used to calibrate the accuracy of the carbon and hydrogen content of the analysis device 1, so as to be able to make targeted adjustments to the analysis device 1. In this embodiment, the standard gas stop valve 31 may also include a first standard gas stop valve and a second standard gas stop valve, and also include a standard gas discharge valve 32 and a standard gas one-way valve 33, which have the same functions as in the above embodiment, so no further detailed description is given. It should be noted that in this embodiment, the gas outlet end of the calibration pipeline 3 can be connected to the sample gas pipeline 2, specifically located between the sample gas one-way valve 23 and the sample gas flow detection meter 24, so that the calibration pipeline 3 can use the sample gas flow detection meter 24 to detect the flow of the standard gas delivered to the analysis device 1, and a flow detection component can be solved in the manufacturing process to achieve the purpose of solving the cost.

[0055] Further, see Figure 1 As shown, in some embodiments, the gas source mechanism includes: a sample gas storage container 6, which is connected to the sample gas pipeline 2 and is used to store the sample gas medium with a carbon content to be measured; a standard gas storage container 7, which is connected to the calibration pipeline 3 and is used to store a standard gas with a standard carbon content; a hydrogen storage container 8, which is connected to the hydrogen pipeline 5 and is used to store a hydrogen medium.

[0056] Furthermore, in some embodiments, the hydrogen storage container 8 includes: a first hydrogen storage tank 81 and a second hydrogen storage tank 82 , which can be controlled to open and close and connected to the hydrogen output section 5 c , so as to be able to supply hydrogen medium to the analysis device 1 separately through the hydrogen pipeline 5 .

[0057] Specifically, in the technical solution adopted by the present application, in this embodiment, the hydrogen storage container 8 includes a first hydrogen storage tank 81 and a second hydrogen storage tank 82. The first hydrogen storage tank 81 can be used as the main hydrogen medium storage container in the gas source mechanism, and the second hydrogen storage tank 82 can be used as a standby hydrogen medium storage container in the gas source mechanism. When the hydrogen medium in the first hydrogen storage tank 81 is exhausted, the hydrogen medium in the second hydrogen storage tank 82 can be activated, and when the hydrogen medium in the first hydrogen storage tank 81 and the second hydrogen storage tank 82 are both exhausted, the abnormal processing section 5b enters an emergency state. In this embodiment, a time delay condition for hydrogen pressure changes can be set on the pressure sensing unit 51; for example: when the hydrogen medium in the first hydrogen storage tank 81 is exhausted and the hydrogen medium in the second hydrogen storage tank 82 is activated, the hydrogen medium pressure in the output detection section will change in a certain time period. If the hydrogen medium pressure in the output detection section returns to the normal threshold value during this time period, the pressure sensing unit 51 does not need to send a control signal to the abnormal processing unit 52; on the contrary, if the hydrogen medium pressure in the output detection section does not return to the normal threshold value during this time period, it indicates that the hydrogen medium in the first hydrogen storage tank 81 and the second hydrogen storage tank 82 have been exhausted. At this time, the pressure sensing unit 51 sends a control signal to the abnormal processing unit 52 to make the abnormal processing section 5b enter an emergency state.
