UBE gas separation membranes have been in service for over 35 years in various sectors. Following extensive research, UBE’s first commercial gas separation membranes for hydrogen recovery were installed in an oil refinery in 1986. A few years later, in 1989, UBE expanded its membrane line and applications, installing the first UBE CO2 separator to purify biogas.
Certainly, a first and effective introduction of UBE’s CO2 separator would be its role in supporting carbon neutrality in a pure and straightforward manner.
How does it work? In this gas separation membrane model contains numerous numbers of hollow membrane fibers with high gas selectivity, compressed biogas (feed gas) enters its structure, resulting in product gas (non-permeate gas). This is because CO2 and other molecules, such as H2O or O2, permeates UBE’s polyimide membranes faster than CH4, resulting in that permeating speed differences, transforming biogas into biomethane (CH4).
Without a doubt, UBE CO2 stands out for its high selectivity, purifying biomethane up to 99.5% and yielding biomethane up to 99.8%. Furthermore, it consumes very low energy, with 0.15 kW as the minimum compression energy for 1 Nm3 of biogas for a 97% methane yield.
On the other hand, UBE CO2 separator also offers attractive advantages in terms of hydrogen sulphide, humidity, and temperature.
Finally, regarding the projects and sectors to which it can be applied, thanks to its versatility and advanced configuration, UBE CO2 separator is proving its high efficiency, usefulness, and excellent results in a wide range of industries.
