Abstract

The invention discloses a method for producing a soap-making wax and a low-melting-point paraffin. According to the method, on the basis of a common sweating de-oiling technology, optimally, the raw material and aqueous solutions of more than two matters capable of reacting and generating gas are respectively emulsified and then sweated and air flow is utilized to carry liquid oil by a wax layer so as to forcefully separate the wax from the oil in a sweating process, so that the yield of the target product is increased and the production period is shortened. The method disclosed by the invention has the advantages of low equipment investment, simple production process, low operation cost, no solvent pollution, and the like.

Description

technical field [0001] The invention belongs to the technical field of petroleum wax production, in particular to a method for producing soap wax and low-melting paraffin wax. Background technique [0002] Petroleum wax is a general term for various wax products obtained from waxy distillates after crude oil is refined and processed, including liquid paraffin, soap wax, paraffin wax and microcrystalline wax. Soap wax and paraffin are produced by the steps of dewaxing, deoiling, refining and molding of lubricating oil fractions in crude oil. They generally contain n-paraffins, a small amount of isoparaffins and naphthenes and other components. Usually, the melting point of soap waxes is between Between 40°C and 52°C, the melting point of paraffin is between 50°C and 74°C. [0003] Dewaxing is a process in which lubricating oil fractions are used as raw materials to prepare wax paste with an oil content of about 10-30%. The dewaxing process mainly includes press dewaxing and ...
