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.
