Description
(54) СПОСОБ ДЕПАРАФИНИЗАЦИИ НЕФТЕПРОДУКТОВ(54) METHOD FOR DEPARAFINIZATION OF PETROLEUM PRODUCTS
Изобретение относитс к области нефтепереработки , в частности к способу депарафинизации нефтепродуктов.This invention relates to the field of refining, in particular to a method for dewaxing petroleum products.
Известен способ депараф.Ш1иза1 ;ии нефтепродуктов кристаллическим карбамидом в присутствии растворител (бензин «галоша) и активатора (метанол).The known method of deparaf. S1 of; 1, and petroleum products of crystalline urea in the presence of a solvent (gasoline "galosh) and an activator (methanol).
Цель изобретени - повышение качества нефтепродуктов и упрош,ение ороцесса - достигаетс тем, что в качестве растворител -The purpose of the invention is to improve the quality of petroleum products and to improve the oro-process is achieved by the fact that as a solvent
активатора примен ют нитроалкан, содержащий обычно 0,2-1 вес. % воды. Пример 1. Различные фракции нефти смешивают в экстракторе с обводнен ым нитроэтаном и кристаллическим карбамидом прл отношении сырье : нитроэтан : карбамид, равном 1:2:1. Смесь интенсивно перемешивают в течение 20-30 мин при 15-30°С и депарафинлрованный продукт отдел ют от карбамиднего комплекса в делительной воронке. Полученные результаты приведены в табл. 1.activator, nitroalkane is used, containing usually 0.2-1 wt. % water. Example 1. Various fractions of oil are mixed in an extractor with water-flooded nitroethane and crystalline carbamide in the raw material: nitroethane: carbamide ratio equal to 1: 2: 1. The mixture was vigorously stirred for 20-30 minutes at 15-30 ° C and the dewaxed product was separated from the carbamide complex in a separatory funnel. The results are shown in Table. one.

П|редмет изобретени 1. Способ депараф низации нефтепродуктов кристаллическим карбамидом в присутствии активатора и растворител , отличающий- 5 с тем, что, с целью повышени качества нефтепродуктов и упрощени процесса, в качестве растворител - активатора примен ют обводненный низший нитроалкан. 2. Способ по п. 1, отличающийс тем, что используют китроалкан, содержащий 0,2- 1 вес. % воды.Method of Invention 1. A method for de-paraphaling oil products with crystalline urea in the presence of an activator and a solvent, which is 5 in order to improve the quality of oil products and simplify the process, water-saturated lower nitroalkane is used as an activator solvent. 2. A method according to claim 1, characterized in that a citroalkane is used containing 0.2 to 1 weight. % water.
