Providing a accomplished research of CO2 compression, transportation strategies and issues of safety for publish combustion CO2 catch purposes for a 900 MW pulverized difficult coal-fired energy plant, this booklet assesses strategies for reinforcing the strain of CO2 to pipeline strain values with a minimum quantity of power. 4 kinds of compressors are tested intimately: a standard multistage centrifugal compressor, integrally geared centrifugal compressor, supersonic surprise wave compressor, and pump machines. The examine demonstrates that the complete compression strength is heavily regarding the thermodynamic strategy and isn't made up our minds via compressor potency by myself. one other challenge addressed is that of CO2 pipeline delivery from the compressor outlet website to a disposal web site below warmth move stipulations. The booklet additionally gains an research of simulations and types which are used to figure out the utmost secure pipeline distance to next booster stations as a functionality of inlet strain, ambient temperature, thickness of the thermal insulation and ground-level warmth flux stipulations. This booklet specializes in compression in addition to transportation tactics with specific emphasis at the defense hazards on the topic of the shipping of CO2. an important challenge by way of environmental safety is making sure special and trustworthy possibility id. As dangers can basically be controlled successfully in the event that they are accurately pointed out, difficulties related to the release and atmospheric dispersion of CO2 also are discussed.

For this study, the assumed efficiency was the same as in conception C3. 10). In this case, polytropic efficiency is 84 % for the first and 56 % for the eighth stage. C6—Eight-stage integrally geared compressor with 6 intercoolers and the inlet inter-stage gas temperature of 20 °C. The rejection of the 7th intercooler offers the potential for significant heat integration with the power plant process. For this study, the assumed efficiency was the same as in conception C5. 10). Polytropic efficiency is 84 % for the first and 70 % for the eighth stage.

4). The high-pressure (HP) compressor also has two compression sections with intercooling in between. Both the LP and HP compressors have the second section impellers arranged in a back-to-back configuration with the impellers in the first section. 44 M. Majkut and A. 1 General Introduction The power of the CO2 compressor may amount to approximately 8–10 % of the rated power of the entire turbine set, which substantially increases the thermal power plant own needs and, as a consequence, reduces the net efficiency of electricity generation.

This offers the potential for significant heat integration without compromising the compressor performance. The combination of compression and heat recovery creates an even more impressive energy efficiency advantage by recovering 70–80 % of the electrical input energy in the form of useful heat. The available heat could be used to regenerate amine solutions or pre-heat the boiler feed water. 3 Compression and Pumping with Supercritical Liquefaction CO2 is either compressed to the desired pressure using a gas compressor or it is liquefied at lower pressures by using refrigeration systems and then pumped to the desired pressure value.
