摘要
洛阳石化2#催化装置原使用轻柴油作为再吸收剂,对贫气中C_3、C_4组分吸收效果并不理想,为了进一步提高C_3、C_4组分的吸收效率,回收贫气中的高附加值组分丙烯,将再吸收塔吸收剂由轻柴油改为顶循环油,经过一段时间的使用后发现,C_3、C_4组分吸收率提高了34.44%,贫气中丙烯组分降低了11.16%,液化气中丙烯含量升高了1.713%。
Luoyang Petrochemical 2 # catalytic converter originally used light diesel oil as a reabsorbent, which had a poor absorption effect on C3 and C4 components in lean gas.In order to further improve the absorption efficiency of C3 and C4 components, the high The value added component propylene, the reabsorption tower absorber from light diesel oil to the top circulating oil, after a period of use found C3, C4 component absorption rate increased by 34.44%, propylene gas component decreased by 11.16% Propylene content in liquefied gas increased by 1.713%.
