塔中油田汽提法原油脱硫化氢工艺技术

为了减少塔中联合站处理装置中大量高含H2S原油对非抗硫工艺管线和设备造成的严重腐蚀,消除外输原油和天然气H2S浓度严重超标带来的安全隐患,中国石油塔里木油田公司借鉴国内首套重质原油干法汽提脱硫装置在塔河油田三号联合站试验成功并且安全平稳运行的经验,在塔中作业区水平一转油站建成了日处理能力1 000 t的汽提法原油脱硫装置,对塔中一号气田试采单井原油进行脱硫处理,通过对温度、进液量及汽提比等参数进行不断优化将装置调整到最佳运行状态,采用3018固体脱硫剂对汽提脱硫装置中产生的高含H2S尾气进行全部回收,有效地防止了大气污染。

Application of Gas Stripping Method to Crude Oil Desulfurization in Tazhong Oilfield

In order to mitigate severe corrosion of a large number of crude oil with high hydrogen sulfide on non-sulfur resistant process pipelines and equipment in gas treatment unit of Tazhong joint station and eliminate potential safety hazards resulting from seriously excessive hydrogen sulfide concentration in exported crude oil and natural gas,Tarim Oilfield learns from successful experience obtained in the first heavy crude oil dry method gas stripping desulfurization unit of 3# joint station and has built a gas stripping desulfurization unit with 1000t/d capacity in an oil transfer station of Tazhong operation area for removal of sulfur from crude oil produced in trial production single well of Tazhong 1# gas well.Continuously optimized are such parameters as temperature,liquid volume and gas stripping ratio so at to adjust the unit until it reaches the optimum operating status and adopted is the 3018 solid desulfurizing agent so as to recover high hydrogen sulfide exhaust fully from the gas stripping desulfurization unit and accordingly atmospheric pollution is mitigated effectively.The results of analysis on social and economic benefits show that the unit can achieve desired objectives.
