How it works
The Oil Skimming module is primarily used to separate oil and solids from the circulating water during the water wash phase. This is normally the last phase of the cleaning process.
The module contains two special integrated coalescors for the separation of the oil. The first stage is solid separation; the next stage is oil/water separation.
The module consists of four compartments. The oil is accumulated in the oil compartment and is eventually pumped to the customer pipeline for reprocessing. The oil-free water is directed back to the tank cleaning nozzles to continue the water wash. This recirculation of the washing water results in a significant reduction of total water consumption compared to alternative tank cleaning procedures, which generally use a once-through water flow.
