煤气化在线分析预处理系统的新设计应用

New Design and Application of the Pretreatment System for Coal Gasification Online Analysis

以中海石油华鹤煤化有限公司为例,分析了煤气化装置中在线分析预处理系统在使用过程中出现的问题,介绍了预处理系统的新设计方案,主要对取样探头、一级预处理系统、二级预处理系统、公用工程部分进行了改进。实践结果证明,新的设计方案完全满足了煤气化粗合成气煤灰大、水分多、温度高的工况条件,保证了分析仪表系统安全、稳定、可靠的运行。

With CNOOC Huahe Coal Chemical Ltd.as an example,the problems of online analysis pretreatment system of coal gasification unit during the operation were analyzed,and the new design scheme of pretreatment systemwas introduced.The improvement was made mainly on the sampling probe,primary pretreatment system,secondary pretreatment system,and utilities.The result showed that new design scheme fully met the operating conditions of high coal ash,moisture and temperature for crude syngas of coal gasification,ensuring the safe,stable and reliable operation of the analysis instrument system.
