DONGLI OL100 Strong Acid Cation Exchange Resin

DONGLIOL100 is insoluble in acids, alkalies, and all common solvents, however exposure

to free chlorine and other strong oxidizing agents over a long period of time will attack the

polymer matrix, causing the resin moisture retention to increase.

PROCESS DESCRIPTION

The coalescing agent has two distinct areas of operation:

The area of Coalescence

Micro-droplets of oil are captured by the oleophilic resin Purolite OL100 forming a film of

hydrocarbon around the material. 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 area of Decantation

The large oil droplets rise to the top of the unit through a “chimney” which is installed to

direct the flow of droplets away from the treated water outlet. Separation is further

assisted by reduction in water velocity which occurs as the water leaves the top of the

chimney and begins its downward passage. The oil droplets combine at the top of the

unit to form a separated layer of hydrocarbon which is discharged continuously via an

automatic liquid level controller.

The treated condensate is taken off continuously at a low level through a side outlet.
