In the full-circulation aqueous solution process, the gas phase from the two-stage separator goes directly to the secondary surface cooler; does the absence of a booster affect the vacuum level in the two stages?

In the full-circulation aqueous solution process, the gas phase from the two-stage separator goes directly to the secondary surface cooler; does the absence of a booster affect the vacuum level in the two stages?
It mainly depends on whether the two-stage water cooler can meet the condensation conditions
If your secondary cooler uses circulating water, it definitely won’t be able to operate.
The water temperature isn’t low enough; using ammonia cooling will work
Reply to 1# dzh751105: We also use a fully circulating urea solution system, with gas separation followed by two cooling stages – stage one and stage two. Circulating water is used for cooling, and the results are quite good:D
