Problems solved by technology
The circulating gas stream output from the polymerization reactor contains ethylene, propylene, hexane, hydrogen, etc. At present, an online chromatographic analyzer is installed on the gas phase circulating gas pipeline of the reactor to analyze the content of each component in the circulating gas online, and the analysis results will automatically participate in the analysis. Adjust the feed amount of the reaction monomer, but due to the long analysis cycle of the gas chromatographic analyzer and the shortcomings of the analysis data lag, the feed amount of the monomer cannot be changed rapidly from time to time, resulting in unstable product quality

The invention provides a system used for monitoring the content of a gas component, and a method thereof. The system comprises: a polymerization kettle used for carrying out a chemical reaction on an input gas monomer; a circulating gas pipeline connected with the polymerization kettle and used for circulating a gas output by the polymerization kettle and an infrared analyzer positioned on the circulating gas pipeline and used for monitoring the component content of the target gas in the gas output by the polymerization kettle. The infrared online analyzer is arranged on the basis of original process flow to carry out real-time analysis of the component content of important technologic gases (ethylene and propylene) in circulation gas, so the monitoring rate is increased; and the feeding amount of the monomer is accurate and effectively regulated according to the obtained component content to guarantee a gas ratio, so the yield and the quality of the product are improved.
Description
technical field [0001] The invention relates to the field of gas monitoring, in particular to a system and method for monitoring the content of gas components. Background technique [0002] The production of ethylene-propylene rubber by the traditional solution method or suspension method is carried out in a polymerization tank, and ethylene, propylene, third monomer or fourth monomer are polymerized in a polymerization reactor under the action of a catalyst to form ethylene-propylene rubber. Among them, the polymerization reaction For the exothermic reaction, the heat of reaction is removed by pre-cooling the raw material and flashing the monomer. At present, the main control of the polymerization kettle is that the flow rate of each monomer and catalyst input into the polymerization kettle is proportional to the flow rate of the gas phase circulating gas stream of the polymerization kettle into the polymerization kettle, and different grades of ethylene-propylene rubber ar...
