Zusammenfassung:An on-line metering device for coke yield comprises a DCS monitoring center, the DCS monitoring center is respectively connected with a flow regulating valve, a gas flowmeter, a CO concentration measuring instrument and a CO2 concentration measuring instrument, an inlet of the gas flowmeter is connected with the flow regulating valve, and an outlet of the gas flowmeter is connected with a reactorprovided with a tail gas exhaust pipeline. And a CO concentration measuring instrument and a CO2 concentration measuring instrument are sequentially arranged on the tail gas exhaust pipeline. According to the metering device, the beneficial effects can be achieved as follows: the total yield of the coke generated in the catalyst regeneration reaction can be accurately calculated, the yield of thecoke at any time can be monitored, and the state of the catalyst in each time period in the regeneration process can be reflected. 一种焦炭产量的在线计量装置,包括DCS监控中心,所述DCS监控中心分别与流量调节阀、气体流量计、CO浓度测量仪和CO2浓度测量仪连接,其中气体流量计的进口与流量调节阀相连,出口与安装有尾气排
