Methanol-rich regeneration in the heat regeneration reflux tank of Linde cryogenic methanol wash
Thread Content
In Linde’s low-temperature methanol wash process, the reflux at the top of the methanol thermal regeneration tower is the location with the highest total sulfur content in the system. By regenerating this methanol before sending it back into the tower, the overall sulfur balance within the tower can be altered, thereby reducing the total sulfur content in the system and minimizing equipment corrosion as well as affecting the quality of the methanol. If anyone has any good ideas, operating procedures, or relevant literature on this topic, please feel free to share them!
It’s not easy to do~~; at low temperatures, methanol tends to absorb sulfides, while at high temperatures the amount of alcohol present increases. This problem also exists in new regeneration~
This idea doesn’t seem very practical; considering energy consumption, it doesn’t seem worthwhile
