文昌13-1/2油田液化石油气(LPG)回收项目是中海石油(中国)有限公司湛江分公司首个海上 LPG回收项目。近年来文昌油田 LPG产品时而会发生铜腐测试不合格情况,本文通过对 LPG 系统硫化氢检测,LPG气样总硫含量测试以及铜片腐蚀产物的能谱测试,发现文昌油田 LPG气样铜腐超标和硫含量超标有关。根据海上油田生产环境特点,拟采取湿法脱硫技术,直接加注脱硫剂的方法治理铜腐不合格问题。现场试验加药点选在进口压缩机进口,这样既可以给脱硫剂与硫化氢反应提供空间和时间,又可以在 LPG系统较前端将硫化氢治理到较低水平,防止了硫化氢在 LPG系统中的扩散。液化气脱硫剂以加注量50mL/min,在现场实践应用的一个月的时间里,可以有效地将铜腐指标从2 a降低到1 a,确保 LPG产品符合国标标准要求。

Wen1 3-1/2 oil field liquefied petroleum gas (LPG ) recycling proj ect is the first offshore LPG recycling project in CNOOC (China)Co.,Ltd.Zhanjiang branch.In recent years, LPG gas copper corrosion exceeding occurs sometimes.By detecting hydrogen sulfide,total sulfur content of LPG gas sample and testing copper corrosion product through energy spectrum test, Wen1 3-1/2 oil field LPG copper corrosion exceeding is concerned with sulfur content exceeding.According to the characteristics of production conditions in offshore oil field,we propose to adopt wet desulfuring technologies———direct inj ection of hydrogen sulfide scavenger to solve unqualified copper corrosion problems.Field test inj ection point is set on compressor entrance,which can provide space and time for reaction between the hydrogen sulfide scavenger with hydrogen sulfide and can also manage hydrogen sulfide to lower levels from upstream of LPG systems,preventing the proliferation of hydrogen sulfide in the LPG system.Liquefied petroleum gas desulfurizer goes with filling volume 50mL/min.During a month’s time of field test,copper corrosion index can be effectively decreased to 1a from 2a,which can ensure that LPG products comply with national standard.
