| titleOfInvention | A kind of technique that methanol extraction method extracts sodium sulphate in three monomer mother liquors |
| abstract | The present invention provides a kind of technique that methanol extraction method extracts sodium sulphate in three monomer mother liquors, the method includes MVR concentrations, methanol is added dropwise, filter filtering, methanol rinsing step, three handled monomer mother liquors are the wastewater mother liquors in the synthesis of three monomers after dealcoholysis, three monomers in three monomer mother liquors containing 170-190kg/t, the sodium sulphate and water of 370-400kg/t, using treatment process of the invention, the sodium sulphate purity extracted from three monomer mother liquors can achieve 98.1-99.5%, sodium sulphate recovery per pass is 91.2-94.8%, three monomers in mother liquor can also further be recycled, three recovery yield of monomer in mother liquor reach 92.80-95.1%, remaining Trace Methanol will not cause the pollution of product in sodium sulphate product, have in industrial production There is significant progress. |
