RefineTek

Project Info

IndustryPhotovoltaic Polysilicon
Product NameMembrane+PSA Hydrogen Recovery & Purification System
Feed Gas CompositionH2: 15-55%, N2: 45-85%, CO2: 1-60 ppmv, CO: 0.01-2 ppmv, CH4: 20-50 ppmv
Feed Gas Flow Rate4,000 Nm³/h (3.39 MMSCFD)
H2 Product Purity>99.999% mol
H2 Recovery Rate>95%
Project LocationInner Mongolia, China
Delivery Date2023

Using RefineTek's proprietary combined membrane separation and PSA process, the project efficiently recovers hydrogen from the tail gas of polysilicon production, purifying it to above 99.999% mol with a recovery rate above 95%. The recovered high-purity hydrogen can be returned to the production system for recycling, significantly reducing the enterprise's feedstock gas procurement cost and supporting green, low-carbon production in the photovoltaic polysilicon industry.
