浅谈一氧化碳生产单元气体检测仪优化布局

Optimization Layout of Gas Detector of Carbon Monoxide Production Unit

摘要

一氧化碳生产单元主要采用氧化工艺生产一氧化碳，以天然气和氧气为原料，在反应器中发生部分氧化反应生成富含一氧化碳的合成气，高温高压的合成气经过急冷降温送至脱碳系统，整个一氧化碳生产单元的塔、罐等压力容器内及管道内都具有易燃易爆的甲烷等可燃气体及易燃易爆、有毒有害的一氧化碳有毒气体。如果设备、管线发生泄漏，极易形成爆炸性危险环境，发生火灾爆炸事故。为了在第一时间检测到泄漏的物料，需在生产单元现场设置可燃气体检测仪和有毒气体检测仪。根据气体检测仪的检测范围及现场实际情况进行优化布局，以便提高检测仪的检测效果及降低检测仪的投入、运维成本。

Abstract

Carbon monoxide production unit mainly adopts oxidation process of carbon monoxide, with natural gas and oxygen as raw material, partial oxidation reaction occurs in the reactor syngas rich in carbon monoxide, high temperature and high pressure syngas after cooling to decarbonization system, the carbon monoxide production unit tower, tank pressure vessel and pipe are flammable and flammable methane and flammable and explosive, toxic and harmful carbon monoxide toxic gases. If the fruit equipment and pipeline leakage, it is easy to form an explosive dangerous environment, fire and explosion accidents. In order to detect the leaking material in the first time, the combustible gas detector and the toxic gas detector should be installed in the production unit site. Optimize the layout according to the detection scope of the gas detector and the actual situation on the site, so as to improve the detection effect of the detector and reduce the input, operation and maintenance cost of the detector.
