A cryogenic air separation unit (ASU) (12) is integrated into a lube oil dehazing process whereby waste nitrogen (16) from "the ASU is used to cool a lube oil base stock to promote the agglomeration (17) and separation (21) of haze-forming constituents in the base stock. Advantageously, the ASU may be part of a gas-to-liquid plant.
Une unité de séparation d'air cryogénique (ASU) est intégrée dans un processus d'élimination de la turbidité d'une huile lubrifiante, dans lequel les déchets d'azote provenant de l'ASU sont utilisés pour refroidir un stock de base d'huile lubrifiante afin de stimuler l'agglomération et la séparation des constituants formant la turbidité, dans le stock de base. Avantageusement, l'ASU peut faire partie d'une installation gaz-liquide.
