The aim of the paper consists in optimising the integration of CO₂ post-combustion capture technology using chemical absorption within the fluidised circulating coal combustion (FCCC) with direct application in glass and cement industries. The authors have performed some comparison of the effects of using primary amines (MEA) and tertiary amines (TEA) in order to reduce energy consumption of regeneration process, and, at the same time, keeping the efficiency of CO₂ capture over 85 %. The paper presents results of an experimental study using laboratory equipment for fluidised circulating coal combustion, and also simulation results of CO₂ post-combustion capture using specialised software HYSYS 3.2.
