Problems solved by technology

[0002] At present, the sample gas used for light hydrocarbon analysis is mostly the hydrocarbons released from the top gas or thermal vacuum distillation degasser. Thermal vacuum distillation degassing requires high vacuum degree, complicated operation, and there are many gas leakage links. At the same time, the mud is boiling. It is easy to pollute the observation window and the gas storage tank, it is extremely difficult to clean, and the mud is easy to splash and cause

Abstract

The invention relates to a full-degassing-lighter-hydrocarbon automatic sample introducing system used for lighter hydrogen analysis. The full-degassing-lighter-hydrocarbon automatic sample introducing system comprises a heating part, a timing control part, a temperature control part, a heat distilling degasser, an automatic sample introducing system, a power supply and an R232 circuit which are assembled in a casing, wherein the timing control part, the temperature control part and the heating part are connected together. A mud slurry pot of the heat distilling degasser is arranged on the heating part, the heat distilling degasser and the automatic sample introducing system are connected with the A end of a T-shaped electromagnetic valve of the automatic sample introducing system by the sample gas outlet of the heat distilling degasser, and the automatic sample introducing system is connected with the R232 circuit. The invention has the advantages of full automation, and no boiling phenomenon if the mud slurry is heated; the danger is reduced, the pollution of the chromatogram post caused by the separation of heavy hydrocarbon is avoided, quantitative tubes are used for sample introduction, the consistency of the sample introducing quantity at each time is guaranteed, and the analyzing performance of the instrument is improved.

Description

technical field [0001] The invention relates to a sample collection and sampling equipment used for light hydrocarbon analysis, in particular to a fully de-light hydrocarbon automatic sampling system used for light hydrocarbon analysis. Background technique [0002] At present, the sample gas used for light hydrocarbon analysis is mostly the hydrocarbons released from the top gas or thermal vacuum distillation degasser. Thermal vacuum distillation degassing requires high vacuum degree, complicated operation, and there are many gas leakage links. At the same time, the mud is boiling. It is easy to pollute the observation window and the gas storage tank, it is extremely difficult to clean, and the mud is easy to splash and cause harm to the operator; at the same time, in the early sampling work of light hydrocarbon analysis, quantitative injection needles are used to manually take quantitative The sample gas is injected into the light hydrocarbon chromatographic analysis instr...
