Hollow Fiber Membrane Devices for Gas/Liquid Mass Transfer and Heat Transfer

Manufacturing processes across numerous industries require efficient heat transfer or gas mass transfer. PEEK-SEP™ hollow fiber devices can meet challenging heat and gas mass transfer application needs encountered in many industries including:

Heat transfer

Lightweight PEEK tube and shell heat exchangers can handle both liquids and gases (single or two phase duties) where chemical durability and resistance to fouling and corrosion are critical. PEEK heat exchangers offer substantial weight, size, space and cost savings over heat exchangers manufactured from exotic alloys.

Removal of Gases from Liquids or Dispersion of Gases into Liquids

PEEK hollow fiber contactors are designed to efficiently remove gases from liquids or disperse gases into liquids in the most demanding industrial applications, including processing of surfactant solutions, solvents and oils.

Integral absorption/membrane contactor

Absorption processes that utilize chemical or physical solvents are ubiquitous gas separation unit operations. However, conventional absorption column based absorption technology is frequently energy-consuming or expensive to operate because of the frequently reoccurring problems including flooding, foaming, channeling and entrainment.

PEEK-SEP™ hollow fiber membrane contactor (HFMC) is a cost effective alternative to the conventional absorption column. The membrane contactor is an advanced mass transfer device that operates with a liquid on one side of the membrane and feed gas on the other.

PoroGen is currently developing HFMC technology for several applications including separation and capture of CO₂ from flue gases, separation of CO₂ from hydrogen in refinery streams, removal of CO₂ from gas streams in Integrated Gasification Combined Cycle (IGCC) power plants, separation of CO₂ from natural gas (natural gas sweetening) and for natural gas dehydration.
