Abstract： |
The invention relates to a method for recycling carrene of waste gas, wherein the invention uses condense-adsorption method to recycle the carrene of organic waste gas; uses water as cooling medium to condense the waste gas; then uses dimethyl formamide in the stuff adsorption tower as absorber to absorb the carrene; the absorber is analyzed in passive pressure in degrade vaporizer, to regenerate the absorber and form loop-close circulation. The invention has low cost and high efficiency. |
