Experimental system for testing breathing loss and emission of crude oil storage tank

Abstract

The invention provides an experimental system for testing breathing loss and emission of a crude oil storage tank. The experimental system is composed of a hermetic acquisition system 001, a cooling system 002, a branch pressure-dividing system 003 and a sampling and collection system 004, wherein the hermetic acquisition system is composed of storage tank breather valve, a hermetic collector, a pressure meter and other parts; the cooling system is composed of a condenser tube, a bottle at a zero DEG C, a bottle at 80 DEG C below zero, etc.; the branch pressure-dividing system is composed of a pop-off valve, a flowmeter, etc.; and the sampling and collection system is composed of a sampling and sucking pump, an airbag, a sampling needle tube, or the like. Gas produced due to breathing loss of the storage tank enters the hermetic acquisition system via the breather valve, then enters the cooling system via a conduit, undergoes cooling and dehydration and then enters the bottle at 80 DEG C below zero for condensation and sampling of C3 and C4 components. The branch pressure-dividing system is arranged in consideration of instability of breathing loss of the storage tank on spot so as to ensure safety and reliability of testing. Finally, breathing gas enters the sampling and collection system via the flowmeter for collection and sampling.

Description

technical field [0001] The invention relates to an experimental evaluation system, in particular to the detection and sampling of respiratory loss discharge of crude oil storage tanks, the exploration of influencing factors and the test and analysis of respiratory gas, belonging to the field of oilfield loss detection. Background technique [0002] Petroleum and petrochemical industry is one of the main industries of energy consumption and greenhouse gas emissions in my country. Its energy conservation and emission reduction actions have an important impact on my country's realization of the energy consumption per unit of GDP and carbon dioxide emission intensity targets during the "Twelfth Five-Year Plan" period. Therefore, since 2011, the State Council, the Ministry of Industry and Information Technology, the National Development and Reform Commission and other relevant departments have issued a series of "Petrochemical and Chemical Industry "Twelfth Five-Year" Development ...

AI Technical Summary

Problems solved by technology

In addition, the research process requires a lot of technical improvement and a lot of manpower and material resources to ensure accurate measurement

Therefore, there is no reasonable and complete experimental evaluation system for testing the breathing loss of crude oil storage tanks that is suitable for various working conditions and has high precision.
