“…The CO 2 stream is firstly compressed slightly above the critical pressure; the compression energy expenditure is minimized by using multiple intercooled stages. The number of stages results from a compromise between efficiency losses and investment costs: Most of the studies (Abu-Zahra et al, 2007), (Romano et al, 2010), indicates an optimum between four and seven stages. Afterward, CO 2 is cooled thus entering the liquid phase area.…”

This paper, which is part of a special issue of the International Journal of Greenhouse Gas Control, gives an overview of the latest achievements in the pre-combustion decarbonisation route for the production of electricity with CO2 capture. Pre-combustion technologies applied to two different fuels are considered, natural gas and coal, since they cover most of electricity production from fossil fuels worldwide. The work first discusses in detail the different sections in which a power plant with pre-combustion CO2 capture can be divided. For each section, the available technologies with corresponding advantages and disadvantages are presented. Next, the plant lay-outs for natural gas and coal proposed in literature, including heat & mass balances and the economic assessment, are discussed. In general, research activity in pre-combustion decarbonisation for power production focused more on coal than on natural gas-based plant since in the latter case the plant complexity and costs are not competitive with post-combustion CO2 capture, which is a technology on the verge of commercialization. Finally the paper briefly discusses pre-combustion CO2 capture in industry especially those projects where CO2 is captured and stored or used for EOR

Considering the uncertainty of economic conditions, multi-objective optimisation can be favoured to single-objective optimisation for process design.However, from the Pareto sets generated by multi-objective optimisation it is not obvious to identify the best one, given that each solution is optimal with regard to the selected objectives. A method taking into account the economic parameters uncertainty to support decision making based on the Pareto-optimal solutions is proposed. It uses a Monte-Carlo simulation to define the probability of each of the Pareto optimal configuration to be in the list of the best configurations from the economical point of view. For a given economic context defined the most probable best configurations are identified.The proposed method is applied to two cases: the CO 2 capture in power plants and synthetic natural gas production from biomass resources. The results allow to identify the most attractive system designs and give recommendations for the process engineers.

“…Figure 3 presents the process blockflow diagram and Tables 2&3 summarize the modeling assumptions and nominal operating conditions considered in this study. The process models are established with flowsheeting software using literature data [18,9,7,26,22]. The reforming reactor is modeled as an isothermal reactor following the approach described in [22].…”

“…Besides performance estimates and thermodynamic arguments, no economic analysis is however performed. In [26] the thermodynamic and engineering aspects of pre-combustion natural gas power plants are studied without including energy integration and economic aspects. However, in [3] it is shown how heat recovery for reactants preheating can increase the H 2 yield by 10%.…”

Within the challenge of greenhouse gas reduction, hydrogen is regarded as a promising decarbonized energy vector. The hydrogen production by natural gas reforming and lignocellulosic biomass gasification are systematically analyzed by developing thermo-economic models. Taking into account thermodynamic, economic and environmental factors, process options with CO 2 mitigation are compared and optimized by combining flowsheeting with process integration, economic analysis and life cycle assessment in a multi-objective optimization framework. The systems performance is improved by introducing process integration maximizing the heat recovery and valorizing the waste heat. Energy efficiencies up to 80% and production costs of 12.5-42$/GJ H2 are computed for natural gas H 2 processes compared to 60% and 29-61$/GJ H2 for biomass processes. Compared to processes without CO 2 mitigation, the CO 2 avoidance costs are in the range of 14-306$/t CO2,avoided . The study shows that the thermo-chemical H 2 production has to be analyzed as a polygeneration unit producing hydrogen, captured CO 2 , heat and electricity.
