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.
