Membrane recovery of VOCs gas
Features:
Compression + condensation + membrane separation;
Realize the recovery of petroleum ether solvents in pharmaceutical companies;
Secondary membrane module. The first stage realizes the separation of oxygen and nitrogen. The secondary membrane module realizes the separation of petroleum ether and other non-condensable gases. Nitrogen reuse.
Features:
Compression + condensation + membrane separation;
Realize the recovery of acetone solvent in fine chemical enterprises;
The separated nitrogen can be reused as a protective gas after being compressed, separated and dried.
Features:
Compression + condensation + membrane separation;
Realize the recovery of methylene chloride solvent;
The concentration of dichloromethane on the permeate side dropped significantly to meet the emission requirements. Air can be used again as a protective gas for the process.
The reuse of part of the air greatly reduces the burden on the back-end VOCs treatment device.
