Dehumidification using High-Performance PAN-based Composite Hollow Fiber Membrane
This invention relates to a polyacrylonitrile (PAN)-based membrane suitable for dehumidification and oxygen enrichment, with a proprietary PDMS selective layer. The substrate material is PAN, which is a low cost and commonly available polymer for membrane fabrication. The membrane is made by coating the substrate with the selective layer. The membrane may also be suitable for gas separation, air separation, paraffin-olefin separation, oxygen enrichment, CO2 capture, hydrocarbon recovery, and volatile organic compounds separation.
Dilution Air Processing Unit for Reduced Transmission of Airborne Infectious Diseases
The Dilution Air Processing Unit (DAPU) is an ideal solution for small and medium businesses to prepare themselves for the Covid-19 new normal by employing an enhanced air ventilation technique. The DAPU system allows the creation of zones (e.g. sickbays, waiting rooms, etc.) within workplaces with no recirculation of air. This prevents cross-contamination of unclean air in between the zones. This solution is suitable for hotels and other premises to be used for quarantine purposes. The DAPU consists of the following key features: Provides 100% fresh air supply with no recirculation Reduces airborne particles exposure by greater than 60% Achieves 25% energy efficiency in providing 100% fresh air supply as compared to conventional systems Uses fully portable modular approach Can be easily retrofitted to any existing air-conditioning system resulting in lower implementation cost The DAPU can also be deployed in any area without an existing air-conditioning system making it highly versatile.
