摘要
针对南山终端液化气铜片腐蚀不合格问题,从检验报告入手,分析铜片腐蚀不合格的原因是液化气中含有硫化氢、元素硫、硫醇等杂质。在对比液化气湿法和干法脱硫工艺及特点的基础上,提出干法脱硫是南山终端液化气脱硫的首选技术。实际生产表明,使用W702复合氧化物精脱硫剂+W107多功能吸附剂组合的干法脱硫技术,可有效脱除南山终端液化气中的含硫杂质,使铜片腐蚀试验达标。
According to the test report, the Liquefied Petroleum Gas（LPG） product contains hydrogen sulfide, ele- mental sulfur, mercaptan and other impurities, therefore has caused copper strip（corrosion） test is unqualified in Nanshan terminal. Based on LPG wet and dry desulfurization process and characteristics, the dry desulfurization technology is the first choice to LPG desulfurization of this terminal.The production practice indicates that it is effective for using the combination of ＂W702 composite oxide fine desulfurizer agent and W107 multifunctional adsorption agent＂ to remove these sulfur impurities from the LPG product of Nanshan terminal.
