“…The main advantage is that only very few components in the liquid phase have to be modelled, namely H 2 O, the dissolved salt called AAS (amino acid salt) and the final reaction product. All reaction intermediate products as well as dissolved molecular CO 2 in the liquid phase have not to be considered, the latter due to the Figure 6: Reaction scheme in the amino acid salt solution, as presented in [7] assumption that the reaction is nearly instantenous and the CO 2 concentration in the liquid is negligible. This means that if a molar flow rateṄ CO 2 of gaseous CO 2 crosses the phase boundary, a source term increases the molar quantity of the reaction product and a sink term decreases the molar quantity of the educts (H 2 O, AAS) such accounting for the stoichiometrics.…”

“…The now unloaded liquid from the desorber bottom is partly evaporated in a thermosyphon and partly led back to the absorber via two heat exchangers in order to cool down to the absorber temperature. The solvent used is an amino-acid salt solution, as described in [7]. The underlying chemical reaction is shown in figure 6.…”

This paper deals with the Thermal Separation Library, which is intended to be used for absorption and rectification processes. Two example calculations show how the simulation speed can be increased by choosing the right way to set up the equations. One example refers to the ordering of the substances in the substance vector and one refers to the modelling of equilibrium processes. An example of use presented is the CO 2 absorption in a post-combustion carbon capture plant. The transient simulation results are compared to measurement data obtained in a Siemens pilot plant.

“…Chemical and physical absorption (i.e., amine process and Selexol solvent, respectively) have drawn considerable attention due to their relatively high technical maturity and feasibility for large scale capacities. However, challenges, such as solvents chemical instability and high energy requirements for solvent regeneration [42] should be taken into account. The adsorption and membrane processes are also considered promising CCS technologies due to their potential for lower energy consumption for CO 2 separation compared to absorption.…”

Investigating the Plasma-Assisted and Thermal Catalytic Dry Methane Reforming for Syngas Production: Process Design, Simulation and Evaluation

Abstract:The growing surplus of green electricity generated by renewable energy technologies has fueled research towards chemical industry electrification. By adapting power-to-chemical concepts, such as plasma-assisted processes, cheap resources could be converted into fuels and base chemicals. However, the feasibility of those electrified processes at large scale has not been investigated yet. Thus, the current work strives to compare, for first time in the literature, plasma-assisted production of syngas, from CH 4 and CO 2 (dry methane reforming), with thermal catalytic dry methane reforming. Specifically, both processes are conceptually designed to deliver syngas suitable for methanol synthesis (H 2 /CO ≥ 2 in mole). The processes are simulated in the Aspen Plus process simulator where different process steps are investigated. Heat integration and equipment cost estimation are performed for the most promising process flow diagrams. Collectively, plasma-assisted dry methane reforming integrated with combined steam/CO 2 methane reforming is an effective way to deliver syngas for methanol production. It is more sustainable than combined thermal catalytic dry methane reforming with steam methane reforming, which has also been proposed for syngas production of H 2 /CO ≥ 2; in the former process, 40% more CO 2 is captured, while 38% less H 2 O is consumed per mol of syngas. Furthermore, the plasma-assisted process is less complex than the thermal catalytic one; it requires higher amount of utilities, but comparable capital investment.

A controllability analysis of a pilot‐scale CO₂ capture plant using ionic liquids

Nowadays there is a world concern on the impact and effect of large CO2 atmospheric concentrations on human health. Fossil‐fuel combustion processes in power plants are among the major contributors to this issue. Hence, it becomes important to develop new clean and sustainable processes aimed to reduce the amount of CO2 released to atmosphere by combustion processes in power plants. One of the best feasible manners to achieve this purposes lies in the use of a closed‐loop control system able to keep the amount of green‐house gases under specification even in the presence of unexpected scenarios. Of course, CO2 capture has been extensively researched in the past. However, in this regard the industrial practice has consisted in using Amines leading to sustainability and safety issues. Hence, it makes sense to seek for new and potentially environmental friendly process design to address CO2 reduction from power plants but applying a new type of sustainable stripping solvents. In this work we address the sustainable CO2 reduction issue from a process control point of view applying a previous design proposed by our research team based on the deployment of Ionic Liquids (IL) as potential green solvents and developing an efficient and decentralized multiloop control system. We demonstrate that the closed‐loop system is able to maintain the CO2 concentration levels under specification by testing in presence of several demanding scenarios. Overall, from an economic, sustainable and control point of view it looks feasible to replace the traditional amines‐based CO2 capture process by other alternatives based on the application of IL as potential green solvents. © 2016 American Institute of Chemical Engineers AIChE J, 62: 3298–3309, 2016
