Removal NH₃ and Amine using activated-carbon at Amine-based CO₂ Capture Process

Through COP21 Paris Agreement in December 2015, a global conference for reduction of greenhouse-gas emissions was deduced. As an effort to reduce greenhouse gas, CCS (carbon capture & storage) technology can directly reduce 12% of the total greenhouse gas emissions, and is an essential alternative for reduction of greenhouse gas emissions in climate-friendly energy use and industrial production, However, CO₂ capture technologies using amine need to be refined because they can cause emission of a small amount of amine and carcinogen. This study conducted an adsorption experiment to control a small amount of amine by using various activated carbons. Fixed bed reactor with activated-carbon was used to remove amine (2-aminoethanol; primary amine) and NH₃. To investigate the main factors between activated-carbon and amine, the specific surface area, morphology, impregnation and activated-carbon were measured by using BET and EDX. As an experimental result, it was confirmed that the removal rate of amine and ammonia were 99% and 12 ~ 20%, respectively.
