Spiral Wound Gas Separation Membrane

‌Working Principle

The spiral wound gas separation membrane is made by rolling flat membranes that preferentially allow organic compounds to permeate. It primarily consists of feed spacers, permeate side spacers, flat membrane sheets, a central tube, membrane housing, and stress resistors. Compared to tubular gas separation membranes, spiral wound membranes offer higher packing density and lower manufacturing costs.

The membrane system is equipped with corresponding metal components that connect to other equipment and piping, allowing the metal membrane components to be reused. Like tubular membranes, spiral wound membranes can separate organic gases from conventional gases like air, nitrogen, oxygen, and carbon dioxide, achieving organic gas concentration, purification, and gas cleaning.




Product Features

High Membrane Performance: High concentration factor, large processing capacity, and stable separation performance.

Long Membrane Life: High swelling resistance, with strong adhesion between the support layer and functional layer.

Component Safety: The conductive flow grid on both sides of the membrane is proprietary, forming a conductive path with the metal shell, central tube, and end cap, effectively dissipating static electricity and eliminating safety risks.

High Swelling Resistance: All materials, including the base membrane, functional layer, sealing parts, and adhesive, are modified for high swelling resistance, allowing long-term use in organic solvent environments. The service life exceeds five years.


Application Areas

Oil and Gas Recovery: Including vapors from loading/unloading trucks, storage tank vents, gas station vapor recovery, and tanker cleaning.

Chemical and Pharmaceutical VOC Recovery: Including recovery of organics from reactor vents and vacuum pump degassing.

Organic Monomer Recovery: Including propylene, ethylene, natural gas light hydrocarbons, and butadiene recovery.
