Low-temperature methanol wash lean methanol pump
Thread Content
I’m seeking advice from experts: At our plant, the filter at the inlet of the pump used for treating lean methanol in the low-temperature methanol washing process gets clogged frequently, with this happening once every two days; before, it used to take half a month to a month before such blockages occurred. Analysis conducted by Sinochem showed that the FeS content is 17% and the Fe2O3 content is around 30%, while other components contain no iron. Experts, could you help analyze where these iron particles might be coming from?
The equipment is severely corroded; could it be that the water content in the system is a bit high?
What is the methanol washing process? What is the precision rating of the coarse/fine filter? Should it be put into use? What is the precision grade of the pump inlet filter? What is the water content in methanol?
This depends on the material used for the equipment in low-temperature methanol washing processes, such as the materials for H2S and CO2 absorption towers, medium-pressure flash towers, and reabsorption towers

It is likely there is a problem with the operation of the regeneration tower
