Abstract
The present invention relates to methods for the production of an ammonium salt wherein sour water stripper gas is reacted with an aqueous medium and wherein the sour water stripper gas (SWSG) is obtained from stripping, preferably steam stripping, of sour water comprising organic compounds, wherein the sour water was submitted to a treatment T1 to reduce the concentration of organic compounds in the sour water before stripping. The present invention also relates to methods for the production of an ammonium salt wherein sour water stripper gas and (concentrated) ammonia are reacted with an aqueous medium such that the ratio (mol:mol) of the total amount of ammonia (NH3) provided by the sour water stripper gas stream to the total amount of ammonia (NH3) provided by the concentrated ammonia stream is at least 1:20. The present invention also relates to methods for the production of an ammonium salt wherein sour water stripper gas is reacted with an aqueous medium and wherein the total amount of acyclic C1-C9 saturated hydrocarbons comprised in the sour water stripper gas is less than 0.2 mol %.
