Membrane-method recovery process for realizing zero emission of volatile organic compound

The invention discloses a membrane-method recovery process for realizing the zero emission of a volatile organic compound. Waste gas which is generated by an organic compound generation system and contains the volatile organic compound directly enters a membrane separation system or is cooled and then enters the membrane separation system. A membrane can be separated by using the difference between the pressures of the upstream and downstream sides of the membrane as impelling force. Gas with high content of the volatile organic compound is obtained on the permeation side of the membrane through enrichment. Gas with low content of the volatile organic compound is obtained on the non-permeation side of the membrane. The gas with the high content of the volatile organic compound on the permeation side of the membrane enters a condensation system to directly obtain part of the organic compound. Meanwhile, uncondensed gas returns to the organic compound generation system, and the gas with the low content of the volatile organic compound on the non-permeation side of the membrane returns to the organic compound generation system. The two flows of returned gas pass through the organic compound generation system, are mixed with a part of the volatile organic compound, and re-enter the membrane separation system for next circulation. According to the process, any emitted gas is eliminated, and the zero emission is realized. The process plays an important role in recovery of an organic solvent.
