Design of the ammonia vent pipeline for low-temperature methanol washing.
Thread Content
Since the shift unit cannot rely solely on the ammonia scrubber to remove ammonia from the shift gas, I would like to ask those of you familiar with the low-temperature methanol washing unit: 1. Which design company designed it? 2. What is the operating condition? 3. And how should the ammonia discharge pipeline be designed? 4. How often should ammonia drainage be carried out? 5. Does the ammonia removal operation affect the stable operation of the sulfur recovery unit? PS: The low-temperature methanol wash unit of the poster was designed by Linde; under normal operating conditions at full load, the gas flow rate is 26.3 w Nm3/h
The owner’s question is more suitable to be addressed in the process system design section.
