METHOD OF OIL SLUDGE PROCESSING

摘要

FIELD: oil and gas industry.SUBSTANCE: oil sludge is delivered from a sludge collector by a pump under pressure up to 1.0 MPa and flow rate up to 10 m/h to a pipe furnace; oil sludge is heated up to temperature of 110-120°C and delivered to a coaslescer filled with coalescent material in the form of granite macadam with bulk density of 1.36-1.40 t/mand size of particles from 5 up to 50 mm; oil sludge is processed in the coaslescer by steam coming from the flow centre and perimeter and by water at the outlet, then the processed product is delivered to a horizontal settler and in the settler it is separated into oil phase and water phase.EFFECT: improving separation degree for highly stable oil sludge.2 dwg, 1 ex
