What are the consequences of an alarm indicating high pressure in the hydrogen sulfide concentration tower in the Lind process, low-temperature methanol washing process? What impact does it have on the backend system?
High tower pressure makes gas lift difficult, resulting in high pressure and increased load on the regeneration tower
Interlocked nitrogen stripping occurs, causing overpressure in the subsequent system; the temperature of the entire system rises, and the parameters of the gas exiting the tower exceed the specified limits, so the feed gas is sent to the flare
The hydrogen sulfide concentration in acidic gases decreases, resulting in significant heat loss.
