FIELD: petroleum and gas processing. ^ SUBSTANCE: diesel fuel is cooled in flow evaporator of refrigeration machine to temperature found from equation T = 15.70.426 - 25 and separated via sedimentational centrifugation, at separation factor 2000-2500, into dewaxed diesel fuel and paraffinaceous sediment containing solid paraffins. Sediment is further separated by filtration into filter sediment, mainly containing solid paraffins, and dewaxed diesel fuel. ^ EFFECT: increased yield of dewaxed diesel fuel, increased degree of purity of solid paraffins, and reduced power expended on cooling and feedstock purification. ^ 4 cl, 1 tbl |
