Our pressure swing adsorption (PSA) system is an innovative and highly efficient technology. It is the perfect solution for the recovery and removal of carbon dioxide from process gases such as synthesis gas streams and steel-work gases.
In the case of synthesis gases, PSA technology is used to recover CO2 from upstream, high-pressure raw syngas streams or low-pressure off-gas streams generated by steam methane reforming or gasification processes. In many cases, PSA technology is a more cost-effective alternative to conventional washing systems due to its lower investment and operating costs.
In the steel industry, PSA technology can be used to efficiently remove CO2 in direct reduction or blast furnace off-gases. The process removes maximum amounts of CO2 yet leaves valuable gas components such as H2, CO, CH4 in the gas stream for further processing.
PSA systems for the recovery or removal of CO2 can operate with feed gas pressure levels ranging from approximately 7 to 35 bar(g) and with a minimum CO2 feed gas content of around 10 vol.-%.
A CO2 PSA unit can achieve a product purity of up to 95 vol.-%, with unit capacities ranging from a few thousand Nm³/h to around 300,000 Nm³/h.
