摘　　要：研究发现,当加氢处理设备添加更多的新氢时,甲烷的含量也会相应提高。此外,如在反应器中添加活性更强的催化剂,这些因素都可能导致脱硫后的循环氢的浓度上升。在892~909 kg/m3的原料油中,成分的变化相对较小,因此,对于脱硫后循环氢甲烷的含量的影响也很有限。通过提高排放氢的数量,能够有效地降低循环氢甲烷的浓度,从而达到减少甲烷积聚的目的。如果生产条件允许,可以通过增加新的氢气的浓度并降低反应的温度来实现。为了维护甲烷的稳定性,应将其冷却至40~50℃,并确保其能够被有效地溶解。文章结合实际,分析深冷分离装置进口甲烷含量高的后果及处理措施。Study found that methane levels increased when they added more new hydrogen.Moreover,if more active catalyst FFX4 is added to the reactor,these factors may all increase the concentration of circulating hydrogen after desulfurization.From 892 to 909 kg/m3,the composition changes relatively little,so they have a limited effect on the content of circulating hydromethane after desulphurization.By increasing the amount of hydrogen emitted,we can effectively reduce the concentration of circulating hydrogen methane to reduce the accumulation of methane.If production conditions permit,we can increase the concentration of new hydrogen and reduce the temperature of the reaction;to maintain the stability of methane,it should be cooled to 40~50℃ and ensure that it can be effectively dissolved.This paper discusses the consequences of high methane content in deep cold separation device and the treatment measures.
