CA 2497677

A method for treatment of caustic effluents, a spent caustic refinery effluent from a source (14) is supplied to a submerged combustion gas evaporator (10) in which hot combustion gas containing carbondioxide is injected into the caustic liquid to concentrate the liquid and convert a hydroxide constituent to a carbonate. Where the caustic effluent is from a petroleum refinery, oil in the waste liquid is separated from the aqueous constituent in an oil separator (20) before, during or after concentration.

Selon les procédés de l'invention, on transfert un effluent caustique usé de raffinage dans un évaporateur à gaz de combustion immergé, dans lequel du gaz de combustion chaud renfermant du dioxyde de carbone est injecté dans le liquide caustique de manière à concentre ledit liquide et à transformer le constituant hydroxyde en un carbonate. Lorsque l'effluent caustique provient d'une raffinerie de pétrole, on sépare l'huile présente dans le résidu liquide du constituant aqueux avant pendant ou après la phase de concentration.
