Providing a finished research of CO2 compression, transportation procedures and issues of safety for submit combustion CO2 seize functions for a 900 MW pulverized tough coal-fired strength plant, this ebook assesses suggestions for reinforcing the strain of CO2 to pipeline strain values with a minimum quantity of power. 4 varieties of compressors are tested intimately: a traditional multistage centrifugal compressor, integrally geared centrifugal compressor, supersonic surprise wave compressor, and pump machines. The research demonstrates that the full compression energy is heavily with regards to the thermodynamic technique and isn't decided by means of compressor potency on my own. one other challenge addressed is that of CO2 pipeline shipping from the compressor outlet web site to a disposal website below warmth move stipulations. The booklet additionally positive factors an research of simulations and versions 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 makes a speciality of compression in addition to transportation methods with specific emphasis at the security hazards on the topic of the shipping of CO2. an important challenge when it comes to environmental safety is making sure distinctive and trustworthy chance id. As risks can basically be controlled successfully in the event that they are accurately pointed out, difficulties concerning the release and atmospheric dispersion of CO2 also are discussed.

7 presents results obtained from the calculations. 06 MW in interstage cooler 6. 50 MW. Such a high rise in the flux of exchanged heat is mainly related to the rise in the CO2 heat capacity near the critical point (Fig. 3). At the same time, this also causes a very significant increase in the heat exchange surface area. 12. 13). The investment cost for an integrally geared compressor is lower than for a single-shaft compressor train. This is the result of the compact design with fewer impellers and with smaller impeller diameters.
Thermoeconomic evaluation of CO2 compression strategies for post-combustion CO2 capture applications, 2009). 0, User Guide, 2008) to predict thermodynamic properties of the CO2 stream at required conditions and quantify the performance of each compression chain option. Within the Aspen Plus environment, the Benedict, Web and Rubin with extension by Starling (BWRS) and the Redlich and Kwong augmented by Soave (LKP) equations of state for real gases were used within relevant ranges of pressure and temperature for the process compressor.
8). Polytropic efficiency changes gradually from 84 % for the first to 70 % for the eighth stage. For a comparative analysis of the influence of the inlet gas temperature on the compressor power requirement, the available cooling water under possibly lower ambient conditions (15 °C) was originally used in this option. The adequate inlet gas temperature is 20 °C. 9. 8). 9). 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.
