In recent years, increased attention being given to reducing CO2 emissions in the environment related to human activities. The main contribution to the emission (about 40 %) are in the flue gases, waste from large thermal power plants (TPP). Since electricity consumption by 2030 year will double, energy must achieve a significant reduction in CO2 emissions from the combustion gases. To do this, begin to take root in the TPP effective technology of carbone capture and storage. The most advanced technology is «Chilled ammonia process», developed by «Alstom». Specific consumption heat for the regeneration of the solution is 2 GJ/t of CO2, which is equivalent to consumption of about 1 t steam/t CO2.
