“…As in the previous case, H 2 is produced via naphtha steam reforming followed by a WGS reaction. The most efficient CO 2 capture point in steam reforming facilities is upstream the PSA unit [10]. Chemical absorption with ADIP-X solvent (a mixture of methyl diethanolamine (MDEA) and piperazine) leads to a capture efficiency of 95% of the total CO 2 emissions, which corresponds to 552 kt/a of CO 2 .…”

“…The model of the capture unit was based on a previous in-house study at Utrecht University [10]. The H 2 concentration entering the PSA must be equal to or greater than 70 mol% for an economical PSA process that achieves 85% per-pass H 2 separation [24].…”

“…Furthermore, CO 2 capture can be implemented in hydrogen manufacturing units using commercially available technology in a cost-effective manner since the CO 2 stream is emitted at relatively high pressure. Moreover, waste heat integration from nearby facilities may reduce the energy (and cost) penalty of the capture unit [10].…”

“…With a current global polyols market of about 6.7 Mt/a, a demand of 0.12 Mt/a of CO 2 for polymer application is estimated if the European polyol market continues to grow at the expected rates [11]. However, this amount is small compared to the CO 2 emissions from industrial hydrogen units (220 Mt/a of CO 2 , [10]. To achieve a substantial CO 2 emission reduction, the same amounts of CO 2 waste captured at the refinery should be used as feedstock for polyol synthesis.…”

Keywords:Carbon capture and utilisation CO 2 economy CO 2 -based polyols CO 2 emissions reduction Pedigree analysis A B S T R A C T CO 2 utilisation is gaining interest as a potential element towards a sustainable economy. CO 2 can be used as feedstock in the synthesis of fuels, chemicals and polymers. This study presents a prospective assessment of carbon capture from a hydrogen unit at a refinery, where the CO 2 is either stored, or partly stored and partly utilised for polyols production. A methodology integrating technical, economic and environmental models with uncertainty analysis is used to assess the performance of carbon capture and storage or utilisation at the refinery.Results show that only 10% of the CO 2 captured from an industrial hydrogen unit can be utilised in a commercial-scale polyol plant. This option has limited potential for large scale CO 2 mitigation from industrial sources. However, CO 2 capture from a hydrogen unit and its utilisation for the synthesis of polyols provides an interesting alternative from an economic perspective. The costs of CO 2 -based polyol are estimated at 1200 €/t polyol, 16% lower than those of conventional polyol. Furthermore, the costs of storing the remaining CO 2 are offset by the benefits of cheaper polyol production. Therefore, the combination of CO 2 capture and partial utilisation provides an improved business case over capture and storage alone. The environmental assessment shows that the climate change potential of this CO 2 utilisation system is 23% lower compared to a reference case in which no CO 2 is captured at the refinery. Five other environmental impact categories included in this study present slightly better performance for the utilisation case than for the reference case.

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.
