ABSTRACT:
A process is provided for recovering a solvent vapor from a mixed gas of the solvent vapor and air. From a vessel storing a mixed gas of the solvent vapor and air, the mixed gas is passed through a compressor to be compressed to a low degree, the resultant compressed mixed gas is introduced to a first absorption column, where said compressed mixed gas is brought into contact with a first absorbent to absorb and recover a greater part of the solvent vapor. A gas coming out from the first absorption column is introduced to a second absorption column, where said gas is brought into contact with a second absorbent.
