What is the methanol consumption of your system? Low-temperature methanol washing

Thread Content

What is the methanol consumption of your system? 60WT low-temperature methanol washing – that’s about 3 tons per day, right? What are the reasons for excessive methanol loss?

This device consumes 2 tons of methanol per day for MTBE production, recovers 0.38 tons, with a yield of 96%. The losses are also huge

300,000-ton synthetic ammonia plant: designed consumption is 10 kg/h, while actual consumption is 500 KG/day

It would be best to explain the production capacity of the device, as this will facilitate comparison and help identify the reasons.

I’ve heard that in some units, the high reflux position at the top of the tower and the low efficiency of the demister result in liquid being carried in the gas sent out, causing severe losses of methanol. Solution: Replace the high-efficiency demister and lower the reflux position.

30W methanol: daily consumption of 1.3 tons

450,000 tons of synthetic ammonia; 2.4 tons per day of methanol. Issues with the operation of the methanol water tower have resulted in excessive levels of methanol in the wastewater discharged; Methanol droplets carried in exhaust gases, flash vapor, and emission gases ; Fluctuations in the outlet pressure of the low-temperature methanol washing unit cause methanol to be carried in the purified gas ; Leaks from the device ;
