| The KPS (Enclosed №1) that will be supplied in carbon steel painted with epoxy tar, will be positioned before the Chemical-Physical Depuration plant on the same mobile skid. The flow in the KPS will be assured from a screw pump for boat with manual gear variator that will suck the liquid to be treated from the accumulation tank. A local flow meter installed on the discharge side of the pump will allow to set the flow rate at the design value . The oil/water mixture enters the first stage over an inlet distributor pipe. This, for the new separator enlarged first stage, achieves gross oil and solid separation. Large oil droplets will rise with a high velocity to the developed oil layer and solids will sediment to the bottom of the first stage. The oily water containing very small oil droplets then enters the plate packs (2nd stage) where separation, as described earlier, takes place. The developed oil layer which is above the plate packs is separated from the water outlet by an oil dam and the oil level will flow by gravity over two adjustable oil skimmer to an integrated oil chamber or an external oil collecting tank. The 3rd stage consist of the outlet chamber with a trough where the clean water flows over its edge to the outlet of the separator. |
