Method for producing petrochemical raw material

摘要

Problem to be solved: to provide a petrochemical raw material production method capable of efficiently producing an oil chemical raw material, regardless of the type of the resin contained in the mixture, in the case where petrochemical raw material is made from a mixture containing a plurality of kinds of resins, and the oil refining equipment can be used as it is, and the type of the resin contained in the mixture is efficiently made.Manufacturing method of petrochemical raw materialFrom a mixture containing said plurality of resinsNo specific resin dissolvedResin other than the specific resin is dissolved to obtain a resin solutionResin dissolution processThe process of treating the raw material oil containing the resin dissolution solution by the oil refining apparatus andAndThe resin dissolution process isThe relative energy difference based on the Hansen solubility parameter for the particular resin is 1 superThen, a solvent having a relative energy difference of 1 or less based on the Hansen solubility parameter for the resin other than the specific resin is selectedThe solvent is contacted to the solvent to dissolve the resin other than the specific resinManufacturing method of petrochemical raw material.No selection
