天然气压气站场风险计算与措施分析

分析了某天然气长输管道工程的压气站可能存在的风险,采用TNT当量系数法对压气站内泄漏天然气可能产生的灾害进行了评估,预测其对周围敏感目标可能产生的影响,并对站场进行火灾、爆炸危险性评价,结果表明：在采取各种安全措施补偿后,压气站及压缩机组的火灾、爆炸危险指数均降低,危险程度均降至＂较轻＂。针对天然气压气站场工程可能产生的环境风险,制定了切实可行的具体的事故防范和应急措施。

Risk Calculation and Corresponding Measures of the Gas Compression Station

The possible risks of the gas compression station in the gas transmission pipeline were analyzed.The possible hazards caused by the gas leakage were assessed and the possible effects on the sensitive objects near the station were forecasted by means of TNT equivalence coefficient method.The fire and explosion hazards to the station were also assessed.The results showed that the fire and explosion hazard indexes of the gas compression station and the compressor set were reduced,the hazard level dropped down ...
