Can low-temperature methanol washing remove thiophene?
Thread Content
Due to changes in raw materials, the gas composition may sometimes contain thiophene. Can the low-temperature methanol washing process remove thiophene? Thank you
The problem is not whether it can be removed, but that thiophene solidifies at low temperatures, causing blockages
The removal of organic sulfur by low-temperature dehydration is very limited; not only thiophene, but also other organic sulfurs are difficult to remove.
The removal capacity is limited; even if removal is possible, regeneration and precipitation are difficult, which is likely to affect the washing efficiency of methanol
