“…There is a growing interest in implementing flexible operation of PCC plants as modelling studies demonstrate improvements to economic and technical performance (Cohen et al, 2010b;Cohen et al, 2010a;Husebye et al, 2011;Arce et al, 2012;Chen et al, 2012;Cohen et al, 2012;Zhang et al, 2012;Mac Dowell and Shah, 2013;Bui et al, 2014b;van der Wijk et al, 2014;Mac Dowell and Shah, 2015).…”

Flexible operation has the potential to significantly improve the economic viability of post-combustion CO2 capture (PCC). However, the impact of disturbances from flexible operation of the PCC process is unclear.The purpose of this study was to investigate the effects of flexible operation in a PCC pilot plant by implementing step-changes for improved dynamic data reliability. The flexible operation campaign was conducted at the CSIRO PCC pilot plant at AGL Loy Yang using monoethanolamine (MEA) absorbent. The pilot plant was operated under a broad range of transient conditions (changing flue gas flow, liquid absorbent flow and steam pressure) to capture the dynamics of a PCC process during flexible operation. The study demonstrated that the dynamics of flue gas flow rate was faster than absorbent flow rate. The greatest CO2 removal % was achieved at the lowest flue gas flow rate or at the highest absorbent flow rate; however the latter provided improved energy efficiency. The steam pressure parameter could adjust the temperature of all columns simultaneously which can be used to compensate for effects from ambient conditions or heat losses. These results verify the technical feasibility of flexible PCC operation and provide a suitable dataset for dynamic model validation.

“…The similar concepts were proposed, such as European value chain for CO2 [18], CO2 value chain [19], CCS chain [20]. Some applied cases have been studied, such as the value of flexibility in the CCS chain of coal-fired power generation with post combustion carbon capture [21]. K. Damen et al also proposed a chain analysis method (called CCS chain) to compare energy production costs and CO2 avoidance costs in a consistent matter, taking electricity and hydrogen production systems as case study.…”

A carbon chain analysis is applied to assess a complex energy conversion system with CO2 Capture and Storage (CCS). A coal integrated gasification combined cycle, with CCS, which co-produces electricity and liquid fuels (IGCC-LF-CCS) is taken as a case study. A process simulation method is used to estimate the technological data, and balance the heat and electricity for the whole system. Carbon and energy flows are calculated to evaluate the mass conversion efficiency and the energy efficiency. The results show that in the case in which one third of the coal is allotted to synthesize liquid fuels, globally 60 % carbon is captured for storage, 19 % carbon is transferred to liquid fuels, 19 % carbon is emitted to the atmosphere as CO2, while the remaining carbon is discharged as solid waste. For the energy flow, 28.1 % of total higher heating value of coal is converted into the liquid fuels. The net electricity efficiency is 20.7 % accounting for the power demands by air separation, CO2 capture and compression. Three scenarios with different ratio of resource to produce electricity and liquid fuels with or without CCS have been studied and compared. This work will provide useful information for the coal resource utilization with CCS in a carbon-constrained world.

“…Also, other authors have developed and adapted the life cycle assessment methodology by integrating CCS technology in the energy units [10,11]. Kather et al and Husebye et al studied the technical and economic effects of the capture, transport and storage technology integration in the pulverized coal combustion power plant [12,13]. In another paper the authors developed a database on the emissions generated in the power plant stage, and they determined the stripper performance in terms of energy [14].…”

“…Over the last period, several scientific papers have analyzed different power generation technologies based on coal using the life cycle assessment [8][9][10][11][12][13][14][15][16][17][18][19]. The scientific analyses focused on CO 2 capture post and oxy combustion technology integration in the energy power plants [8,9].…”

The objective of this paper consists of evaluating the coal life cycle and proposing technical solutions for reducing GHG emissions. After applying the life cycle assessment on the coal life cycle, it was noticed that the power engineering stage has a bigger environmental impact on different indicator impacts. In order to reduce the GHG emissions the CO 2 chemical absorption process was integrated in the power plant based on the circulating fluidized bed combustion technology. Two cases were analyzed: super-critical and ultra-supra-critical parameters. For each case the environmental indicators (global warming potential, abiotic depletion potential, human toxicity potential, photochemical potential, acidification potential, eutrophisation potential) were evaluated in order to estimate the environmental effects on the coal life cycle with CO 2 capture process. After the integration of the CO 2 capture post-combustion process into the power plant, the GHG emissions decreased from 450,760 CO 2 equiv. tons to 75,937 CO 2 equiv. tons for super-critical parameters and from 438122 CO 2 equiv. tons to 73245 CO 2 equiv. tons for ultra-supra-critical parameters respectively. In order to increase the absorption capacity of the MEA solvent the SO 2 emissions were reduced from flue gases and consequently the acidification potential was reduced too in both cases. On the contrary, the amount of fuel increased in order to maintain the functional unit as a result of the efficiency penalty of the CO 2 capture integration in the power plant.
