Embodiment 1

[0028] see figure 1 , an on-line sampling system for a gas-liquid mixed medium, comprising a sampling system, a gas-liquid separation system, a cooling system, and a nitrogen purging system.

[0029] Among them, the sampling system includes a medium inlet 1, a first medium inlet process valve 2, a second medium

[0030] Quality inlet process valve 3, liquid sampling valve 6.

[0031] Specifically, the liquid sampling valve 6 communicates with the top of the gas-liquid separation system. The bottom of the gas-liquid separation system communicates with the inside of the glass bottle 33 through the sampling needle 32 and a sampling valve 31 is provided between the gas-liquid separation system and the sampling needle 32 . The adsorption tank 34 communicates with the inside of the glass bottle 33 through the sampling needle 32 .

[0032] Specifically, the first end of the three-way ball valve 8 communicates with the top of the gas-liquid separation system. The second end of the...

Abstract

The invention discloses an online sampling system for a gas-liquid mixed medium. The online sampling system comprises a sampling system, a gas-liquid separating system, a cooling system and a nitrogenpurging system. The online sampling system for the gas-liquid mixed medium realizes gas-liquid separation by adopting a second medium process valve, a cooling tank and a gas-liquid separating tank, creates conditions for separately sampling the gas and the liquid, realizes separate sampling of the subsequent gas and separate sampling of the liquid to meet technical requirements of complicated working condition, and solves a sampling problem of complicated gas and liquid coexistence. The online sampling system for the gas-liquid mixed medium is suitable for a gas-liquid mixed medium or a medium generating a large amount of gas after the medium is depressurized. The nitrogen purging system of the invention can discharge the medium into a flare discharge mouth, eliminates the residual of themedium and ensures that the entire system is clean for the next sampling. The nitrogen purging system and the cooling system are not required, so that the entire system is greatly simplified.

Description

technical field [0001] The invention belongs to the petrochemical field, and in particular relates to a method for producing a large amount of gas after a gas-liquid mixed medium or medium is depressurized. [0002] The gas-liquid mixed medium online sampling system of the medium. Background technique [0003] In petroleum, chemical, pharmaceutical and other fields, various liquids or gases are often transported through pipelines. In order to ensure that the transported medium can meet the specified process parameters, the transported medium must be sampled, tested and analyzed at specific points on the pipeline. [0004] In recent years, with the strengthening of environmental pollution and environmental protection requirements and the improvement of people's awareness of environmental protection, domestic petrochemical and pharmaceutical industries have successively installed a number of environmental protection equipment in the environmental field, and the sampler is a w...
