Gas Separation Research Activities

■ Development and synthesis of new polymers ■ Membrane module design using 2D and 3D CAD and utilisation of commercial products ■ Process engineering - comprehensive process simulation using ■ Lab- and pilot plant scale membrane production of the implementation of complex models for gas permeation modules flat sheet membranes (width up to 70 cm) into commercial process simulators

■ Characterisation of polymers and membranes for ■ Pilot plant operation gas transport behaviour ■ Technology transfer and licensee support

Examples of Investigated Separation Tasks

■ Separation of volatile organic compounds (VOC) from ■ Separation of hydrogen from process streams permanent gases ■ Air separation and dehydration ■ Water- and hydrocarbon dew point adjustment of ■ CO2 removal from biogas, natural gas, flue gas and hydrogen natural gas

Successfully Introduced Siloxane Membranes for Hydrocarbon Separation

■ Siloxane membranes are highly selective for hydrocarbons

■ High permeation rates are realised because of thin selective layers

■ Membranes are highly effective in product recovery and emission control

■ Separation of a wide range of solvents, gasoline vapours and monomers like ethylene, propylene and vinyl chloride

■ Efficient system design by process integration

■ More than 1000 references demonstrate the success
