Real-time methane detection device for oil gas fixed top storage tank

Abstract

The invention discloses a real-time methane detection device for an oil gas fixed top storage tank, which comprises a gas collection sealing bag (1), a gas buffer tank (2) and a methane detector (4) which are arranged in sequence, and one end of the gas collection sealing bag (1) is provided with an opening (11). According to the real-time methane detection detection device of the oil gas fixed top storage tank, all methane discharging gas can enter, meanwhile, it is guaranteed that gas flow entering a methane detection instrument is stable in the field detection process, large errors of methane detection data are avoided, real-time and continuous metering of the methane discharging amount is achieved, and meanwhile, the integrated design scheme realizes rapid sampling and rapid detection, and the methane gas emission field detection operation is convenient.

Description

technical field [0001] The invention relates to the field of gas leakage detection, in particular to a real-time methane detection device for oil and gas fixed-roof storage tanks. Background technique [0002] As the second largest greenhouse gas in the world, methane is also the main product of the oil and gas industry. It is attracting more and more widespread and intense attention than ever before at home and abroad. One of the most significant measures of change, it is also the focus of government regulation, investor inquiries, and public debates. [0003] In terms of the contribution rate of methane emissions by industry, the energy supply industry accounts for a relatively high proportion, and nearly one-third comes from the crude oil extraction and natural gas production, gathering and distribution processes in the oil and gas industry. Almost all production processes and equipment links have the possibility of methane emissions. Among them, in the oil and gas prod...

AI Technical Summary

Problems solved by technology

Borrowing petroleum and petrochemical gas leakage detection technology, gas leakage can be detected qualitatively, but the gas leakage volume and gas leakage characteristics cannot be effectively revealed

The existing mature methane gas leakage detection technology is difficult to quantify methane gas emissions due to the lack of necessary on-site detection and real-time detection devices

At the same time, due to the dynamic change process of the material flow in and out of the storage tank, the methane discharge gas from the storage tank also presents the characteristics of irregular instantaneous flow rate surge or decrease, which brings certain difficulties to the detection of methane discharge from oil and gas storage tanks in oil field production.
