PURPOSE: Disclosed is a recovery method of condensable steam using membrane. CONSTITUTION: The system for recovery of condensable steam is carried out by the following steps: a feeding step of mixed steam into a compressor (1), a compressing step, a sending step of condensate into membrane (4) along to the present of trap (7), and a storage step of condensate. To separate a condensable steam from the mixed composition, the mixture passed through a compressor (1) is condensed in the condenser (2) to store in the tank (3). The rest steam from the condenser (2) is sent into the membrane system (4). The condensate in the tank (3) may be again sent into the membrane (4) by the pump (5), and the permeated steam and the condensate are recycled iteratively into the condenser (2) to recover the condensable steam as much as possible.
