摘 要:为了提高酮苯脱蜡装置的含油蜡收率,根据酮苯脱蜡装置的工艺特点,采取了优化酮比大小、卡边操作、降低脱蜡温差;在维持一段滤机进料温度基本不变的条件下,降低去蜡油凝固点,即降低了去蜡油的收率,相应地提高了目的产品(含油蜡)收率。To improve the oily wax yield of acetone-benzene dewaxing unit,the methods such as acetone(methyl ethyl ketone) proportion optimization,Just On-Spec.marginal operation and dewaxing temperature difference reduction were used based on the process characteristics of acetone-benzene dewaxing unit ;Under the condition of keeping the first-stage filter feed temperature basically unchanged,the freezing point of dewaxed oil was decreased,so its yield was reduced,thus the yield of target product(oily wax) has been increased.
