Discussion on dry gas recovery methods
Thread Content
The processes that have been used for the recovery of C3C4 components from dry gas include ammonia-pressure deep cooling as well as stabilization treatment through absorption and desorption. I’m wondering if there are any other methods; also, which of these two methods is more cost-effective?
Cryogenic methods achieve higher recovery rates, but they also consume more energy.
In terms of recovery efficiency and energy consumption, the absorption process is more efficient and reasonable, with better stability. Comparisons were also made in some of our propylene-propane recovery projects, where the recovery efficiency was significantly higher.
