How to deal with oil contamination in methanol from low-temperature methanol washing
Thread Content
I work at a coal-to-oil plant. Recently, in the purification workshop’s low-temperature methanol washing process, the methanol seems to be contaminated by oil for some reason (there is an ammonia washing tower in the previous processing stage). This is resulting in poor performance of the thermal regeneration process; the concentration of hydrogen sulfide and ammonia in the lean stream is high. The lean methanol is transparent but appears brownish-yellow. What methods can be used to address this issue? Previously, some colleagues suggested adding extractors and azeotropic towers. I was wondering if this is feasible; I would appreciate it if you could provide information on relevant modification plans and equipment for reference. Thank you very much
