How to deal with water content in C4, the raw material for MTBE?
Thread Content
Gas fractionation and MTBE combined unit; C4 feedstock for MTBE contains water
Make a raw material buffer tank for water separation
Find the source and have the upstream device cut the water properly.
First, contact the upstream unit to increase water cutting to ensure stable operation upstream. Further enhance the water cut-off in the raw material buffer tank. With more water, more of the by-product tert-butanol is produced as well
A coalescing dehydrator is installed before the feed gas enters the separator, and a propane recovery tank is used to enhance dehydration
The design should require a water cutting bag
We need to analyze it at the source – why should there be water in a carbon four removal device?
Yes! It’s the fact that the catalytic liquefied gas coalescer isn’t working, which causes the liquefied gas to contain water
Two molecular sieve dryers, one in use and one as backup. Dehydration
Water should not be brought in; check whether there is a leak in the bottom cooler of the vapor fractionator
