Short answer: What are the main processes for acidic water stripping?
It is mainly divided into: the single-tower pressurized stripping with ammonia side-line extraction process, the double-tower pressurized stripping process, and the single-tower low-pressure stripping process.
There are mainly 1: the single-tower pressurized stripping process with ammonia extraction via a side stream (hydrogen sulfide is removed from the tower top, while ammonia is extracted via the side stream)； 2. Dual-tower pressurized stripping process (hydrogen sulfide and ammonia are discharged from the tops of the two towers respectively) ； 3. Single-tower low-pressure stripping process (hydrogen sulfide and ammonia are removed from the tower top)
Single-tower pressurized side-line extraction stripping process, two-tower pressurized stripping process, single-tower low-pressure full-blowout stripping process
The acidic water stripping processes mainly include three process flows: single-tower pressurized side-stream extraction stripping, single-tower low-pressure full-blowout stripping, and two-tower pressurized stripping
Ammonia extraction process via acidic vapor stripping side stream – single tower full extraction process
Single tower with side stream extraction, single tower without side stream, dual towers.
Acid water stripping can be implemented using a single-tower process or a two-tower series process. The single-tower process requires less investment and lower energy consumption, but the treatment of the condensed liquid waste generated is difficult to manage; to meet the required treatment standards, it is necessary to extend the process, which increases costs. The two-tower series process is relatively complex, requires high investment and high energy consumption; however, it produces acidic gases at a high concentration in small volumes, and the condensate produced meets the requirements for reuse
