Abstract

A novel compressed air drying method based on a pressurized liquid desiccant dehumidifier is proposed in this paper. An experimental setup of pressurized liquid desiccant dehumidifier associated with a compressed air module is established to verify the novel air drying method and further test the performance. The results show that

under the pressure of 0.5 MPa

the outlet moisture content of air can reach 0.9 g·kg-1. The moisture removal rate increases with the increase of air velocity

solution flow rate and solution concentration under certain pressure. The feasibility of applying liquid desiccant technology to drying compressed air in related fields is verified.
