油气换热系统泄露原因分析及检漏方案

Cause Analysis and Leakage Detection Scheme of Oil-and-Gas Exchange System

摘要: 某化工生产装置中，油气换热系统频繁发生压力波动。本文通过一系列前期检查和原因分析，排除导热油系统故障，进一步检查确认油气换热设备发生泄漏，通过氢气和氦气实施检漏操作分析，明确设备故障点，并做出更新计划。

Abstract: In the chemical production device, pressure fluctuation occurs frequently in the oil-and-gas ex-change system. Through a series of pre-inspection and cause analysis, the failure of heat transfer oil system is eliminated, and the leakage of the equipment in the oil-and-gas exchange system is further confirmed in this paper. Through analysis of leak detection operation by hydrogen and he-lium, the fault point of oil-and-gas exchange system is defined and an update plan is made.
