POWER-ENVIRONMENTAL PROBLEMS OF PRODUCTION AND USE CARBON DIOXIDE

Abstract

Consumption carbon dioxide to increase. Therefore it is important to reduce power expenses for its manufacture. Besides it is necessary to take into account greenhouse effect created by it. All this results in necessity of the joint decision of a power-environmental problem of reception and use СО2. The basic sources carbon dioxide and ways of its manufacture are considered. It is shown, that the production efficiency increase at reception except for СО2 and other products (nitrogen, nitrogen-hydrogen mixture), and also thermal and electric energy. Ways of modernization existing Carbon dioxide plants working on flue gases, formed after burning natural gas are considered. The new power-technological complexes using co-generation and steam turbine plants for production of the electric power and heat are described. For an estimation of a power-environment overall performance carbon dioxide plants of various type by us the modified treatment of TEWI-criterion is offered. It is shown, that in the power-technological complexes simultaneously making «pure» electric and thermal energy, liquid low-temperature carbon dioxide and gaseous nitrogen emission of greenhouse gases in an environment can be reduced on 18 % in comparison with traditional carbon dioxide plant.
