Abstract
A process for the purification of an aqueous stream coming from the Fischer-Tropsch reaction using distillation and/or stripping treatment, a treatment with at least one inorganic base and a treatment with at least one organic base. This process allows at least a part of the aqueous stream coming from the Fischer-Tropsch reaction to be used as process water in the synthesis gas production plant, subsequently sent to the Fischer-Tropsch plant for the production of hydrocarbons.
