FIELD: oil industry. SUBSTANCE: proposed plant includes raw material pipe-line, separator of oil from gas, preliminary dewatering unit with pipe-line to discharge stratal water, apparatus of deep dewatering of oil with pipe-line for disposal of water and apparatus to prepare water. Apparatus to prepare water is connected with separate unions to pipe-line to discharge stratal water from preliminary dewatering unit and to pipe-line for disposal of water from apparatus of deep dewatering of oil. Apparatuses are placed in plant in series as oil flows: first apparatus separating mixture into oil and water in preliminary dewatering unit, then apparatus of deep dewatering of oil and separator to extract gas from dewatered oil. Pipe-line for disposal of water from preliminary dewatering unit and apparatus of deep dewatering are connected to opposite butts of apparatus to prepare water. Oil heater can also be placed ahead of apparatus of deep dewatering. Given plant makes it possible to purify water simultaneously from preliminary dewatering unit and apparatus of deep dewatering of oil and to prepare high-quality water ready to be pumped into water pool. EFFECT: enhanced operational efficiency of plant. 1 cl, 1 dwg, 1 tbl |
