Abstract
A method for treatment of process condensate () in an ammonia plant, wherein the ammonia plant comprises a front-end section producing a make-up gas and a synthesis section where the make-up gas is reacted to ammonia, and said process condensate () is collected from one or more equipment of the ammonia plant and is an aqueous solution comprising ammonia, carbon dioxide and methanol. Said method comprises: stripping said process condensate with low-pressure steam (), obtaining a vapour phase () comprising ammonia, carbon dioxide and methanol stripped from the process condensate; condensing said vapour phase, obtaining a solution () enriched of ammonia and methanol; re-introducing a first portion () of said solution to said stripping environment; recycling a second portion () of said solution to said ammonia plant.
