摘要
以兰炼加氢处理的125N、200N、400N及120BS润滑油基础油为原料,对不同相对分子质量的聚烯烃/聚丙烯酸脂脱蜡助剂DEW-6、DEW-7、DEW-8的脱蜡助滤效果在实验室进行了评价。评选工艺采用关键单元的间歇式过程。试验结果表明,对于125N,DEW-6加剂量为0.05％时,过滤速度提高60％～80％,油收率提高5个百分点,蜡含油降低70％;对于200N,DEW-7加剂量为0.01％时,过滤速度能提高50％,油收率提高5个百分点,蜡含油降低30％;对于400N,DEW-7加剂量为0.09％时,过滤速度能提高150％,油收率提高10个百分点,蜡含油降低30％;对于120BS,DEW-8加剂量为0.09％时,过滤速度能提高60％,油收率提高3个百分点,蜡含油降低30％。
Using the hydrotreated lube base oils of 125N, 200N, 400N and 120BS from Lanzhou Petroleum Refining and Petrochemical Company as feedstocks, the filtration effects of polyolefin/polypropylene-acid-ester dewaxing aids having different relative molecular masses with designations of DEW-6, DEW-7 and DEWo8 were evaluated in the laboratory. DEW-6 at a dosage of 0.05% and DEW-8 at a dosage of 0.09% were added to 125N and 120BS oils respectively; and DEW-7 was added to 200N and 400N oils at a dosage of 0.01% and 0.09% respectively. The results showed that for 125N, 200N, 400N and 120BS oils, the filtration rates enhanced by 60%-80%, 50%, 150% and 60% respectively; the dewaxed oil yields increased by 5, 5, 10 and 3 percentages respec tively; and oil in wax decreased by 70%, 30%, 30% and 30% respectively.
