Abstract

Disclosed is a system for automatic sampling and detection of on-line gas by high-temperature and high-pressure simulator and a detection method thereof. A vacuum manifold I is successively connected to a pressure controller, a gas-liquid separator, a gas automatic metering collector, a first trace quantitative gas collector, and a mechanical pump. On a vacuum manifold II, a high-low pressure convertor, a second trace quantitative gas collector, a gas transferring device, a heavy oil trap, a filtering trap, and a pressure gage head are connected successively. In the present invention, discharged simulation products, enter an empty gas chromatograph at a normal temperature and a normal pressure after treatment, completing on-line detection of an accumulated gas and a stage gas, and improving accuracy of gas composition measurement.
