Methods for enhanced solvent dewaxing, among which the use of modifying additives is promising and inexpensive, are presented. Modifying additives belonging to various chemical classes are described. Polymer compositions based on poly(meth)acrylates with 10-30 C atoms in the alkyl radical are currently the most interesting modifying additives. Use of this type of compounds in solvent dewaxing significantly increases the filtration rate of the feedstock suspension. This affects the increase in plant productivity. At the same time, the yield of dewaxed oil increases by an average of 5% and the oil content in the paraffin slop wax/petrolatum decreases.

改性添加剂在溶剂脱蜡中的应用

介绍了增强溶剂脱蜡的方法,其中使用改性添加剂是有前景且价格低廉的。描述了属于各种化学类别的改性添加剂。基于在烷基中具有 10-30 个碳原子的聚(甲基)丙烯酸酯的聚合物组合物是目前最令人感兴趣的改性添加剂。在溶剂脱蜡中使用这类化合物显着提高了原料悬浮液的过滤速率。这会影响植物生产力的提高。同时,脱蜡油收率平均提高5%,石蜡废蜡/凡士林中含油量降低。
