Alkylation (step reactor) problem
Thread Content
In the alkylation unit, the separation of acids from hydrocarbons is not proper, which results in a high level of acids in the reaction products, as well as hydrocarbons present in the acids. I seek expert advice on this issue
Every family is more or less in the same situation; it’s just a matter of degree, and there are many factors at play.
Normally, we connect three coagulators here, along with an additional fine coagulator, to achieve excellent results
Under normal circumstances, an acidic substance is present; this depends on the size of the acid settling tank. In some alkylation units, the settling tanks are twice as large as the reactors. It is also necessary to pay attention during production to ensure that the acid separation tank is used to separate the acid in a timely manner
May I ask what the size is of the acid separator located below the flash tank in your unit? Thank you.
