Why is the alkylation waste acid degasser operated under negative pressure?
Thread Content
Our company is engaged in low-temperature alkylization with sulfuric acid. Why is the waste acid degasser operated under negative pressure? Is it to evaporate the volatile hydrocarbons? I hope experts can help me.
Volatile hydrocarbons are vaporized, and the vapors are extracted, thereby preventing volatile organic compounds from being released into large tanks and posing safety hazards
Reducing pressure lowers the boiling point, allowing the light components with low boiling points to evaporate and leaving the acid behind
