Abstract: Un método para retirar los contaminantes gaseosos (34) de una corriente de efluente de una fábrica de pasta en forma de condensado de evaporación acuoso (28), condensado de evaporación acuoso (28) que contiene metanol y contaminantes gaseosos seleccionados del grupo que consiste en dióxido de azufre y compuestos de azufre reducido total (TRS) caracterizado por proporcionar un contactor (10) de membrana de fibras huecas que comprende una pluralidad de fibras huecas (12), teniendo cada fibra una pared (22) de membrana hidrófoba porosa que tiene un primer (24) y segundo (26) lados opuestos; hacer fluir el condensado de evaporación acuoso (28) a través de dicho contactor (10), en contacto con los primeros lados (24) de las paredes (22) de las fibras (12); y permitir que dichos contaminantes gaseosos (34) en dicho condensado de evaporación acuoso (28) migren a través de las paredes (22) de la membrana a dichos segundos lados (26) de las paredes de las fibras, dejando una corriente acuosa de metanol en dichos primeros lados (24) de dichas paredes (22).

Abstract: A method and apparatus for the treatment of pulp mill condensates is described. A hollow fiber contactor, incorporating a hydrophobic membrane, was used to remove several undesirable compounds from pulp mill condensates. For example, TRS compounds and SO2 were efficiently stripped from kraft and sulphite mill evaporator condensates, respectively. Methanol was also removed from kraft mill condensates but at a lower efficiency than TRS. Furthermore, other undesirable compounds found in condensates of pulp mills that contribute to the BOD and COD loading to effluent treatment systems were also removed. These contactors are cost effective since air, vacuum or a suitable solvent or scrubbing solution can be used as the stripping medium to drive off through the membrane several undesirable compounds from the feed solution. The undesirable compounds removed can thus be burned in the recovery boiler, lime kiln or a dedicated boiler.
