In this work the part load behaviour of the post-combustion CO₂ capture (PCC) process is evaluated. The net efficiency of the conventional hard-coal-fired power plant decreases from 45.6% at full load to 41.5% at 40% load. The net efficiency with PCC using 7 m MEA (monoethanolamine) as solvent decreases to 34.8% at full load and to 30.1% at 40% load. The pressure of the intermediate pressure/low pressure crossover section has major influence on the efficiency. In part load higher pressures are in advantage due to lower throttling losses. The shutdown of the PCC is a possibility to generate balancing power. A reduced capture rate of 75% leads to a generation of 5% additional power.en1876-61022013207216Elsevierhttps://creativecommons.org/licenses/by-nc/3.0/post-combustion capturepart load behaviourIP/LP crossover pressurebalancing powerTechnikIngenieurwissenschaftenConference Paperurn:nbn:de:gbv:830-882.03162910.15480/882.221810.1016/j.egypro.2014.07.02410.15480/882.2218Other
