摘要：In this paper, studies have been carried out to determine the parameters of the coalescing separation of oilwater emulsions formed as a result of the activities of machine-building industries, spills of oil products and oils using a laboratory experimental setup. In the process of cleaning the used emulsion, methods of coalescence, magnetic separation of metal particles and inertial-gravitational purification are applied. The novelty of this coalescent plant is thin-layered PVC plates, separated by vertical partitions, to increase the contact surface with the emulsion. The degree of separation of water-oil emulsion from suspended solids -92 %, from petroleum products – 59 % was determined. The capacity of the water-oil emulsion separation unit was 7 dm3/min. Depending on the requirements, the purified liquid can be reused, or in other technological processes. As a result of the removal of free oil products by coalescent purification, the particle size increases and the absolute value of the z potential of the dispersed phase of the emulsion decreases.
