摘　　要：为探究海洋石油某终端处理厂天然气腐蚀与化学防护技术,对几种脱硫剂产品的性能进行了室内评价,实验结果表明,吗啉衍生物类脱硫剂CL-03和油溶性三嗪衍生物类脱硫剂CL-04的脱硫性能优异,且加药浓度500mg/L,作用时间大于3h时,可使某海洋石油终端处理厂液化石油气铜片腐蚀程度保持在1b以内,符合国标要求。CL-03和CL-04在现场试验过程中,均能有效去除天然气中的硫化氢并降低液化石油气铜片腐蚀程度,且处理后并不明显影响液化水油气质量。某海洋石油终端处理厂天然气脱硫最佳方案是,在天然气海管登陆点附近使用脱硫剂CL-03,在液化石油气中加注脱硫剂CL-04。In order to investigate the corrosion and chemical protect technology o f natural gas in theoffshore oil terminal treatment plant, some desulfurizer was tested. The result showed the Morpholinederivatives desulfurizer C L -03 and the Oil soluble three triazine derivatives C L -04 are good at scavengingHydrogen Sulfide, and the copper corrosion degree o f natural gas would be less than Level 1b that is aG B , when the concentration o f desulfurizer was 500 mg/L and reaction time was more than 3h. These twodesulfurizers can effectively scavenge Hydrogen Sulfide, reduce the copper corrosion degree o f natural gasand did not affect the natural gas quality. The best plan was used C L -03 near the landing point o f natural gaspipe and was used C L -04 in liquefied petroleum gas.
