DEVICE AND METHOD OF WET COMPRESSED GAS DRYING AND COMPRESSOR PLANT CONTAINING SUCH DEVICE Russian patent published in 2020 - IPC B01D53/26 

FIELD: gas industry.

SUBSTANCE: present group of inventions relates to a device for drying moist compressed gas, for example, coming from a compressor element. Device comprises dryer, which contains liquid drier and is configured to bring compressed gas into contact with dehumidifier. Dehumidifier allows moisture absorption from compressed gas. Dryer is a membrane dryer. Device also contains a circuit, as well as a facility for circulation of the dehumidifier in the circuit in series through a membrane drier with a membrane, which forms a partition between the compressed gas on one side and a liquid dehydrator on the other side of the membrane. Membrane is impermeable or virtually impermeable for gas in compressed gas, but selectively permeable for moisture in compressed gas. Proposed device comprises heat exchanger for liquid desiccant heating and regenerator. Invention also relates to a compressor plant comprising at least one compressor element for gas compression, and a method for drying wet compressed gas.

EFFECT: group of inventions enables efficient and cheap drying of moist compressed gas.
