Abstract ▼ AI-Helper

Interest in hydrogen production to respond to climate change is increasing. Until now, hydrogen has been mainly produced through the SMR (Steam Methane Reforming) process using natural gas. A large amount of CO2 is emitted in the hydrogen production process through SMR, and the gas flow including CO2 generated in the SMR process has different characteristics for each emission source, so it is important to apply a suitable CO2 capture process. In the case of PSA tail gas or synthesis gas, the applicability of an amine-based process has been confirmed or demonstrated close to a commercial level. However, in the case of the flue gas generated from the reformer, it is still difficult to apply the conventional amine-based process because the partial pressure of CO2 is relatively low. Energy-saving innovative absorbents such as phase separation absorbents can be a solution to these difficulties.
