|Objectives||In the industry of materials transformation, the degreasing is a necessary stage before any other surface treatment. It is realized with the help of an aqueous solution containing a detergent, which is to emulsify the oil recovering the part to be degreased. The bath containing the degreaser becomes progressively charged with oil and the degreaser must be frequently replaced, otherwise it becomes quickly inefficient.|
Continuous elimination of oil and recycling of a filtrate containing the degeasing purified agent.
During the separation, the product is fractionated in two phases :
– the filtrate, which is constituted of purified degreasing product and is recycled to a bath.
– the increase in the effective working life of the degreasing solution.
