Description

Technical Field

[0001] This invention belongs to the field of gas storage construction technology, specifically relating to a gas injection separation skid-mounted device and its working method. Background Technology

[0002] In the field of oil and gas extraction equipment, the construction of gas storage facilities is a crucial task. The primary function of gas storage facilities is to regulate the supply and demand balance of natural gas by injecting or extracting natural gas when supply is insufficient or demand increases, thereby ensuring a stable supply. This process requires various separation equipment, such as cyclone separators and filter separators, to separate solid particulate impurities and liquids from the natural gas. Furthermore, intelligent control systems and electrical equipment are needed to achieve precise control of the entire process. Traditional gas storage stations mainly consist of independent cyclone separators and filter separators, which need to be connected through complex pipelines and lines to form a complete system. The advantage of this approach is the flexibility to configure various equipment according to actual needs, but it also has some drawbacks, such as equipment dispersion, large footprint, heavy installation and maintenance workload, and high energy consumption. Simultaneously, the dispersion of equipment complicates coordination and control between devices, which may affect operational efficiency and stability. Finally, the dispersion of equipment leads to significant heat loss between devices, increasing energy consumption and potentially affecting equipment lifespan. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned problems and provide a gas injection separation skid-mounted device and its working method, which solves the problems of large footprint, low operating efficiency and poor stability of existing equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a skid-mounted gas injection and separation device, comprising a cyclone separator, one end of which is connected to an air inlet pipe, and the other end of which is connected to a vent pipe. A safety valve is provided on the vent pipe. The cyclone separator is connected to a filter separator. Both the cyclone separator and the filter separator are equipped with local level gauges, and the local level gauges are connected to a high / low level remote transmission system. The top of the filter separator is connected to one end of an exhaust pipe, and the other end of the exhaust pipe is connected to an exhaust port. The bottom of the cyclone separator is connected to one end of a drain pipe. The bottom of the filter separator is connected to the drain pipe via a third pipe and a fourth pipe. A first valve sleeve-type drain valve is provided on the drain pipe near the cyclone separator, and a second valve sleeve-type drain valve is provided on both the third pipe and the fourth pipe.

[0005] A further improvement of the present invention is that a first ball valve and a second ball valve are provided on the vent pipe, the first ball valve and the second ball valve are respectively located on both sides of the safety valve, and the other end of the vent pipe is connected to the vent port.

[0006] A further improvement of the present invention is that a second pipe is connected between the vent pipe and the intake pipe, and a second electric ball valve and a first shut-off valve are sequentially installed on the second pipe.

[0007] A further improvement of the present invention is that the other end of the air intake pipe is connected to the air inlet, and a first electric ball valve and a first pressure transmitter are sequentially arranged at the end of the air intake pipe near the air inlet, and a pressure indicator is arranged on the first pressure transmitter.

[0008] A further improvement of the present invention is that a second shut-off valve is provided near the cyclone separator in the air inlet pipe, and a pressure indicator is provided on the second shut-off valve.

[0009] A further improvement of the present invention is that the other end of the drain pipe is connected to the drain port, and a second pressure transmitter is provided on the cyclone separator.

[0010] A further improvement of the present invention is that a dew point transmitter is provided on the filter separator, and the dew point transmitter is connected to a differential pressure display alarm.

[0011] A further improvement of the present invention is that the top of the cyclone separator is connected to the filter separator through a first pipe, and a third shut-off valve is provided on the first pipe near the filter separator, and a pressure indicator is provided on the third shut-off valve.

[0012] A further improvement of the present invention is that a third ball valve is provided on the exhaust pipe, and the third pipe is arranged in parallel with the fourth pipe.

[0013] Secondly, the present invention also provides a method for operating a gas injection separation skid-mounted device, comprising the following steps: Gas from the pigging and receiving area is introduced into the inlet pipe and then transported to the cyclone separator. The cyclone separator initially separates the solid particles and liquids carried in the gas and then transports it to the filter separator. The filter separator screens the solid particles and liquids to obtain filtered gas. The filtered gas is then transported to the exhaust port through the exhaust pipe and enters the compressor area. When the cyclone separator becomes clogged and the pressure becomes too high, the safety valve on the vent pipe will automatically open to release the natural gas in the equipment and pipeline to the flare for combustion, ensuring equipment safety. When the liquid volume exceeds the set value, the local liquid level gauge and the high and low liquid level remote transmission will issue an alarm, open the first valve sleeve type drain valve on the drain pipe and the second valve sleeve type drain valve on the third and fourth pipes connecting the filter separator to the drain pipe to drain the liquid normally.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a skid-mounted gas injection and separation device. By integrating and combining a cyclone separator, a filter separator, an air inlet pipe, and a vent pipe into a skid, an integrated skid-mounted gas collection device is formed. The skid-mounted design not only makes the equipment more compact but also optimizes the layout and connection method, thereby improving the operating efficiency of the equipment. In addition, local level gauges and high / low level remote transmission devices are installed on both the cyclone separator and the filter separator, which can monitor the internal liquid level of the equipment in real time, effectively preventing equipment overload and extending the service life of the equipment. This invention also includes a vent pipe and a safety valve. When the equipment malfunctions or the pressure is too high, the vent pipe and safety valve can quickly release the pressure, preventing dangerous situations such as explosion or leakage. This not only protects the safety of the equipment itself but also ensures the safety of the operators and the surrounding environment. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings: like Figure 1As shown, the present invention provides a skid-mounted gas injection and separation device, including a cyclone separator 10. One end of an air inlet pipe 1 is connected to the side wall of the cyclone separator 10, and the other end of the air inlet pipe 1 is connected to an air inlet 26. One end of a vent pipe 6 is vertically connected to the middle of the air inlet pipe 1, and the other end of the vent pipe 6 is connected to a vent outlet 27. A first ball valve 3, a safety valve 4, and a second ball valve 5 are sequentially arranged on the vent pipe 6. A second pipe 19 is connected between the vent pipe 6 and the air inlet pipe 1. A second electric ball valve 7 and a first shut-off valve 8 are sequentially arranged on the second pipe 19.

[0025] A first electric ball valve 2 and a first pressure transmitter 23 are sequentially installed at one end of the air inlet pipe 1 near the air inlet 26. A pressure indicator is installed on the first pressure transmitter 23. A second shut-off valve 9 is installed at the position of the air inlet pipe 1 near the cyclone separator 10. A pressure indicator is installed on the second shut-off valve 9.

[0026] The top of the cyclone separator 10 is connected to the filter separator 16 through the first pipe 12. Both the cyclone separator 10 and the filter separator 16 are equipped with local level gauges 11. The local level gauges 11 are connected to the high and low level remote transmission. The cyclone separator 10 is equipped with a second pressure transmitter 24. The filter separator 16 is equipped with a dew point transmitter 25. The dew point transmitter 25 is connected to the differential pressure display alarm.

[0027] A third shut-off valve 13 is installed near the filter separator 16 on the first pipe 12. A pressure indicator is installed on the third shut-off valve 13. One end of the exhaust pipe 17 is connected to the top of the filter separator 16, and the other end of the exhaust pipe 17 is connected to the exhaust port 28. A third ball valve 18 is installed on the exhaust pipe 17. One end of the drain pipe 15 is connected to the bottom of the cyclone separator 10, and the other end of the drain pipe 15 is connected to the drain port 29. The bottom of the filter separator 16 is connected to the drain pipe 15 through the third pipe 20 and the fourth pipe 21. The third pipe 20 and the fourth pipe 21 are arranged in parallel. The parallel arrangement of the pipes can ensure that the liquid is diverted during the transportation process, reduce the flow rate in a single pipe, thereby reducing the flow resistance and improving the overall flow efficiency. A first valve sleeve type drain valve 14 is installed near the cyclone separator 10 on the drain pipe 15, and a second valve sleeve type drain valve 22 is installed on both the third pipe 20 and the fourth pipe 21.

[0028] The present invention also provides a method for operating a gas injection separation skid-mounted device, comprising the following steps: Gas from the pigging and receiving area enters the inlet pipe 1 through the inlet 26, and is then transported to the cyclone separator 10. The cyclone separator 10 performs preliminary separation of solid particles and liquids carried in the gas, and then transports it to the filter separator 16 through the first pipe 12. The filter separator 16 separates solid particles with a size ≤10μm and liquid particles with a size ≤5μm, and then transports it to the exhaust port 28 through the exhaust pipe 17, and enters the compressor area. When the cyclone separator 10 is blocked, causing excessive pressure, the safety valve 4 on the vent pipe 6 will automatically open to release the natural gas in the equipment and pipeline to the flare for combustion, ensuring equipment safety. When the liquid volume exceeds the set value, the local liquid level gauge 11 and the high and low liquid level remote transmitter will issue an alarm, open the first valve sleeve type drain valve 14 on the drain pipe 15 and the second valve sleeve type drain valve 22 on the third pipe 20 and the fourth pipe 21 connecting the filter separator 16 and the drain pipe 15 to drain the liquid normally.

[0029] Working principle: This invention features a vent pipe 6 connected to the air inlet pipe 1, with a safety valve 4 installed on the vent pipe 6. When the cyclone separator 10 becomes clogged, causing excessive pressure, the safety valve 4 automatically opens, releasing natural gas from the equipment and pipelines to the flare for combustion, ensuring equipment safety. Local level gauges 11 and remote high / low level transmitters are installed on both the cyclone separator 10 and the filter separator 16. When the liquid level exceeds a set value, the first sleeve-type drain valve 14 and the second sleeve-type drain valve 22 discharge liquid normally, effectively preventing equipment overload and extending equipment lifespan. The cyclone separator 10 and the filter separator... All 16 units employ pressurized drainage, with manual valves used to adjust the valve opening for manual drainage. This allows for faster and more stable drainage, improving equipment operating efficiency and stability. The integrated unit is insulated to ensure stable operation in winter, reducing heat loss between devices and lowering energy consumption. The unit includes a distribution box and instrument junction box, with 2 cables branching out to 10 circuits, reducing cable laying by 8 circuits, a reduction of 44%. This reduces cable length and laying workload while increasing the unit's integration, minimizing on-site installation, and ensuring an aesthetically pleasing design.
