Dehydration problem of alkylated feedstock
Dehydration using a coalescer is the simplest method. Have you recovered the liquefied gas and alkylation oil from your alkylated waste acid? Liquefied gas and alkylated oil inside have great economic value. Communicate on QQ1472359555.
It depends on what type of dehydrator you use
The best option is molecular sieves, but they are troublesome to regenerate
We used molecular sieves, which resulted in the highest activity levels usual; four blind flanges had to be installed, but overall things are fine and the performance is good
The filter elements of the coalescer work quite well
Molecular sieve? Does it be necessary to remove water from both the feedstock C4 and the recycled isobutane? Has the moisture content after removal been measured? ‘
As long as there is too much machine debris, no coalescer will work properly
We regenerate regularly, and a lot of water is produced during that process. We also have coagulators, but they aren’t effective
Mm-hmm, yes, I’ve used both molecular sieves and coagulators; the coagulator is more practical.
It is best to use a coalescer in combination with a molecular sieve: the coalescer is used to remove the vast majority of free water, while the molecular sieve is used to remove the dissolved water, ensuring complete dryness. Low consumption, low acid usage
