摘要
小试和侧线实验研究结果表明 ,引起焦化液化石油气铜片腐蚀不合格的主要原因是液化石油气的硫化氢和元素硫含量超标 ,直接原因是其中夹带了微量甚至常量的含硫化氢的胺液。评价、筛选了两种常温液相精脱硫剂。在此基础上提出了一种液化石油气液相常温后精制工艺 ,此工艺可较好地解决液化石油气铜片腐蚀不合格的问题。
The results of experiment showed that the main causes resulting in unqualification of copper corrosion in coking LPG are much higher contents of hydrogen sulfide and element sulfur in LPG.The direct cause is entrainment of small amount of amine containing hydrogen sulfide in the LPG.Two types of desulfuriers for liquid phase and room temperature desulfurizing process were evaluated and selected. Based on the desulfuriers, A process of liquid phase and room temperature desulfurizing process was put forword. This process can solve the problem of unqualification of copper corrosion in LPG.
