Embodiment 1
[0017] Embodiment 1 is the transformation of the methanol washing process in the existing synthetic ammonia, wherein the synthetic ammonia process includes a methanol washing section, an air separation section and a liquid nitrogen washing section, and the methanol washing section includes a carbon dioxide desorption tower, a hydrogen sulfide concentration tower and a methanol regeneration tower, Its characteristics are: when starting the gas conduction, the rich liquid nitrogen in the air separation section or / and liquid nitrogen washing section is injected into the hydrogen sulfide concentration tower. Since the liquid nitrogen is injected into the hydrogen sulfide concentration tower when starting up the gas conduction, the hydrogen sulfide concentration tower obtains the required sufficient cooling capacity, thereby shortening the time for the hydrogen sulfide concentration tower to enter the low-temperature normal working state when starting up the gas conduction, Promptly...
