Embodiment Construction

[0018] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.

[0019] Such as figure 1 As shown in the experimental device for on-line monitoring of hydrogen sulfide produced by crude oil, the main high-pressure gas cylinder 10 is connected with a gas flow controller 8 to control the flow of gas entering the high-temperature and high-pressure reactor 4 . A pressure reducing valve is installed at the front and back of the gas flow controller, which is powered by the auxiliary high-pressure gas cylinder to control the stability of the pressure difference between the front and back of the gas flow controller. A stirrer 5 and a temperature and pressure sensor 7 are arranged in the reactor. A quick-opening valve 6 is connected to the back of the reactor, and the quick-opening valve ...

Abstract

The invention discloses a crude oil produced hydrogen sulfide on-line monitoring experimental device comprising a high-temperature high-pressure reaction kettle, a power injection device and a monitoring device, wherein the high-temperature high-pressure reaction kettle is provided with an inlet and an outlet; the power injection device is connected to the inlet of the high-temperature high-pressure reaction kettle; the monitoring device is connected to the outlet of the high-temperature high-pressure reaction kettle. A power source is provided by adopting a high-pressure gas cylinder, pressure changes in the reaction kettle are monitored by a pressure sensor in real time, on-off of a quick-opening valve is controlled, and the quick-opening valve is closely connected with a hydrogen sulfide monitor. After the pressure in the reaction kettle is higher than the set pressure of the quick-opening valve, the quick-opening valve is opened, gases in the kettle are released, the gas is monitored through the hydrogen sulfide monitor and data is recorded, and finally residual waste gases are treated through an alkali absorption device. The experimental device has the beneficial effects that: 1, the danger coefficient is small, direct contact between a human body and hydrogen sulfide gas is avoided in the whole hydrogen sulfide monitoring process, and leakage of the hydrogen sulfide gas is effectively avoided; and 2, the operation program is simple, and the hydrogen sulfide gas can be monitored in real time.

Description

technical field [0001] The invention relates to a crude oil composition monitoring device, in particular to an on-line monitoring experimental device for hydrogen sulfide produced by crude oil. Background technique [0002] The currently used crude oil H2S monitoring technology is manual sampling monitoring. The operation procedure is the first step: firstly put the crude oil into the high-temperature and high-pressure reactor, and after stirring and heating the reactor, the hydrogen sulfide gas contained in the crude oil is released. The second step: manual sampling. The third step: monitor the hydrogen sulfide content. This monitoring method has the following disadvantages: 1. The risk factor is high. During the monitoring process, it is necessary to obtain hydrogen sulfide gas samples by manual sampling, which increases the probability of hydrogen sulfide gas leakage and endangers the personal health of experimenters. Second, real-time monitoring cannot be achieved. ...
