“…An important feature of gasification plants coupled with pre-combustion CO 2 capture (exhibits here by all investigated concepts) is the ability of hydrogen and power co-generation [23][24][25]. These plants can generate (according to the instant power demand from the grid) either only electricity (peak times), hydrogen and power (transient times) or only hydrogen for energy storage (when power generation is low).…”

The energy conversion systems based on partial oxidation processes (hydrocarbons catalytic reforming, solid fuel gasification) are very promising for integrating carbon capture technologies due to high CO2 partial pressure in syngas to be treated. In these systems, the water-gas-shift (WGS) reaction has a very important place in concentrating the syngas energy as hydrogen and to convert carbon species as CO2. This paper is evaluating various WGS process configurations to be applied in catalytic reforming and gasification designs ranging from the conventional designs (multiple catalytic shift reactors) to more innovative reactive gas-solid systems (chemical & calcium looping) for simultaneous syngas conversion and CO2 capture. As the evaluations show, the reactive gas-solid systems are more promising in reducing energy penalty for CO2 capture as well as to increase the overall energy efficiency and carbon capture rate. As illustrative examples, the coal gasification for hydrogen and power co-generation with carbon capture were assessed.

“…The focus in the mentioned literature was on hydrogen production and reactor performance. Studies have also been carried out on analysis of power generation processes with precombustion capture with Ca-Cu looping [21], auto-thermal reforming [22][23][24][25][26][27] and steam-methane reforming [28]. Analysis of chemical looping systems with more focus on hydrogen production from NG has been reported by Spallina et al [29], Kathe et al [30], Diglio et al [31], Antzara et al [32], and Cormos et al [33].…”

Abstract:In this paper, a gas-fired combined cycle power plant subjected to a pre-combustion CO 2 capture method has been analysed under different design conditions and different heat integration options. The power plant configuration includes the chemical looping reforming (CLR) of natural gas (NG), water gas shift (WGS) process, CO 2 capture and compression, and a hydrogen fuelled combined cycle to produce power. The process is denoted as a CLR-CC process. One of the main parameters that affects the performance of the process is the pressure for the CLR. The process is analysed at different design pressures for the CLR, i.e., 5, 10, 15, 18, 25 and 30 bar. It is observed that the net electrical efficiency increases with an increase in the design pressure in the CLR. Secondly, the type of steam generated from the cooling of process streams also effects the net electrical efficiency of the process. Out of the five different cases including the base case presented in this study, it is observed that the net electrical efficiency of CLR-CCs can be improved to 46.5% (lower heating value of NG basis) by producing high-pressure steam through heat recovery from the pre-combustion process streams and sending it to the Heat Recovery Steam Generator in the power plant.

“…Another place where CO 2 capture technologies are o en employed is in hydrogen generation plants, as investigated by Consonni and Viganò (2005) and Damen et al (2006). Zohrabian et al (2016) researched the polygeneration of hydrogen and electricity. From these investigations, a speci c system with integrated CO 2 capture was found to be more e cient than that without.…”

This study employed simulation software to model the coal-based polygeneration systems (PGSs). The carbon-utilization ratios (η C ), hydrogen-utilization ratios (η H ), and energy-saving ratios (ESRs) were used to quantitatively analyze the performance of various coal-based PGSs. This analysis was based on two parameters: the unreacted gas circulation ratio (r) and the ratio of synfuel energy output to power output (λ). The results indicate that both r and λ a ect the η C , η H , and ESR values. Increasing r was found to increase element utilization and ESRs, and a better performance was achieved when a water-gas shift (WGS) reactor was utilized. The highest η C , η H , and ESR values obtained were 29.08, 37.89, and 17.68%, respectively. Increasing λ was also found to increase element utilization and ESRs. When λ 4 and both unreacted-gas circulation and the WGS reactor were employed, the highest element-utilization ratios (η C 19.59%, η H 37.78%) and ESR (19.78%) were achieved. In the corresponding case where a WGS reactor was not used, the η H value signi cantly improved over the range λ 0.0-2.0.
