Purolite OL100 is a premium grade olephilic resin which acts as a coalescing agent designed for the removal of oil from condensate. This specially treated ion exchange resin is a copolymer of styrene and divinyl benezene which has a high capacity for oil removal and excellent kinetics. Purolite OL100 has very good mechanical strength and superior physical and chemical stability.
It is insoluble in acids, alkalis and all common solvents, however exposure to free chlorine and other strong oxidising agents over a long period of time will attack the polymer matrix, causing degradation and loss of performance.
For further information on the resin properties see the Purolite OL100 Technical Data Sheet or contact us on (01489) 570737.
The coalesce will not be remove dissolved oils and therefore it is to see this unit in conjunction with a separate carbon filter.
We always recommend pilot trials are carried out to confirm that the condensate can be treated successfully with Purolite OL100.
The water containing the suspended micro-droplets of hydrocarbons are fed upflow into the column through a fixed bed of Purolite OL100 contained in the coalescer equipment. The coalescing process equipment has two distinct zones of operation.
Micro-droplets of oil are captured by the bed of olephilic resin Purolite OL100 forming a film of hydrocarbon around the resin beads. Continuous film drainage occurs in the resin bed and large droplets of oil are sheared off at the exit face by the upward velocity of the water. The broken film reforms itself perpetually making the process self regenerating.
The large oil droplets rise to the top of the unit through a funnel or chimney which is installed to direct the flow of droplets away from the treated water outlet. Seperation is further assisted by reduction in water velocity which occurs as the water leaves the top of the chimney and begins it's downward passage to the side outlet. The oil droplets combine at the top of the unit to form a seperated layer of hydrocarbon which is discharged usually via an automatic valve operated by an interface oil/water detector.
ALTERNATIVELY TIME OR VOLUME OF CONDENSATE TREATED CAN BE USED.
