Evaluation of the CO2 capture performance of the University of Regina CO2 technology development plant and the boundary dam CO2 demonstration plant

Publisher Summary The aim of this chapter is to review the CO 2 capture performance from recent test results obtained from two major testing facilities of the international test centre for CO 2 capture (ITC)— the boundary dam demonstration plant and the university of Regina (UR) technology development pilot plant. The facility has been used to evaluate the performance and reliability of absorption-based technologies as well as to obtain process design information under a wide range of operating conditions. The performance is presented in terms of CO 2 capture efficiency, mass-transfer performance, and minimization of heat duty for solvent regeneration. The effects of reboiler heat duty on capture efficiency and operating parameters such as rich- and lean-CO 2 loadings are also evaluated. Also, the energy efficiency improvement for the monoethanolamine (MEA) scrubbing technology resulting from using alternative operating conditions is discussed. In addition, operational challenges such as solvent stability are presented and discussed as a function of both the operating conditions and cost effective operating strategy. A comparison is also made of all the results obtained from the UR technology development pilot plant with those obtained from the boundary dam demonstration plant.
