A method for recovering hydrocarbon vapor wherein permeable mixed gases of high concentration hydrocarbon vapor and the residual mixed gases of low concentration hydrocarbon vapor are separated, through gas separation membrane, from initial mixed gases containing hydrocarbon vapor to absorb permeable mixed gases, and a method for recovering hydrocarbon vapor wherein initial mixed gases containing hydrocarbon vapor are brought into contact with liquid absorbent to recover hydrocarbon vapor, and gases of high concentration hydrocarbon vapor and gases of low concentration hydrocarbon vapor are separated, through gas separation membrane, from treated gases from which hydrocarbon vapor has been absorbed in the preceeding process.
