More Information
Summary:The invention relates to the technical field of mixed gas separation. A variable-temperature adsorptive separation method and an SBS (styrene-butadiene-styrene) production technique are combined to recycle an organic solvent (cyclohexane) in technical exhaust gas in the production processes of polymerization, condensation, drying, solvent (cyclohexane) refinement and the like; and the recycled mixed product can directly enter the existing solvent refinement procedure, so that the cyclohexane can be effectively recycled and reutilized. Compared with the traditional purification recovery method, due to the close combination with the production technique, the method provided by the invention has the advantages of simple technical process and obvious economic effect of purification and recycling, is convenient to operate, and can easily implement industrialization.
