Process Description Feedstock - a water-gas-liquid mixture of high-paraffin oil, is mixed with a circulating light fraction fed from thermal dewaxing unit 4 and sent to separator 1. Gas, formation water and dehydrated oil is removed from separator 1. The latter is pumped by pump 3 into electric dehydrators 2, while mixing with fresh water. Extracted water is mixed with formation water, and dehydrated oil is sent to unit 4, from which circulating light fraction, gas, which is mixed with gas stream from separator 1 and additionally treated stable oil are forcedly removed. The latter is pumped out using pump station 5.
