The invention discloses an electronic-grade water-containing organic matter coupling deep dehydration method, which includes: complete vaporization and superheating of raw materials to obtain superheated gas; membrane separation and rough dehydration; The pure organic gas is pressurized by the heat pump and then exchanges heat with the raw material, and then is cooled by a cooler and filtered by a G5 ultrafiltration device to obtain organic products; molecular sieve regeneration; Distillation treatment. The invention also discloses an electronic-grade water-containing organic matter coupling deep dehydration system, comprising: a preheating and vaporization superheating system, a membrane separation system, a molecular sieve system, and a rectification system. The invention combines the advantages of membrane separation and dehydration and molecular sieve dehydration, and is equipped with heat pump energy-saving technology and thermal coupling design. |
