Development Progress on Recovery Technique of Emitting Oil Vapor by Absorption

Different oil and/or gasoline vapor recovery technique (OVRT) along with its progress at home and abroad is introduced, and the key issues in developing OVRT are put forward to solve. As a more practical and more economical method, the absorption recovery technique at atmospheric pressure and temperature should be given priority to focus onto research over the one at the other operation condition. Then, as the first step of the research, the right absorbent should be sifted out.
