The experimental procedure is non-destructive for the monolith and easy to perform but special care has to be taken to prevent leakage. The method is demonstrated for squared channel monoliths of 100 and 400 cells per square inch (cpsi). Variances in the production process of monoliths introduce an intrinsic channel maldistribution that can be described by a normal distribution. As a consequence, the assumption that a monolith is a bundle of equal channels is incorrect and may introduce significant errors in mathematical models that do not incorporate intrinsic channel maldistribution.

The processes here described (DECAB, DECAB Plus and pH-swing) use a combination of enhanced CO 2 absorption ( ) and / or enhanced CO 2 desorption (based on pH-shift), which contribute substantially to the reduction of regeneration energy. An evaluation of these processes has been developed based on literature data, thermodynamic principles and experimental data. As solvent example, the potassium salt of taurine was selected. The results show that these processes are environmentally friendly (no emissions to the air, lower ecotoxicity) and have lower energy consumption than conventional MEA. The DECAB Plus process has been identified as the option with lower energy consumption (66% of conventional MEA-ie ca 2.4 GJ/t CO 2 ). This study has established the potential of precipitating amino acids as an energy effective alternative to alkanol amines. The future work will focus on determining the cost of CO 2 avoidance and investigating other solvents that will further lead to benefits over conventional processes.

In the first section “practical aspects” two items are addressed: (a) the influence of the flow pattern, i.e. a breathing or pulsating flow versus continuous flow, on the breakthrough behavior; and (b) the risk of desorption: the possibility that adsorbed contaminants are released from the filter. The second section “new materials” deals with the use of carbon monoliths. The third section “modeling” discusses a gas mask model that has been implemented in a software tool that simulates chemical and biological incidents. Keywords: Adsorption, gas mask, carbon monoliths, modeling, incidents.

The column uses activated carbon and operates under the strongly fluctuating concentration conditions of an industrial plant. An important aspect of this study was to investigate the influence of water vapor in the feed on the performance of the adsorption column. During regeneration of the carbon, unforeseen reactions of HFP on carbon occurred at elevated temperatures, imposing constraints on the regeneration conditions. A two-dimensional mathematical model for the adsorber worked well. Design calculations were performed on the basis of the experimental results. The Dubinin−Radushkevich model described the adsorption equilibrium substantially better than did the Langmuir model. It is demonstrated that a correct adsorption isotherm is more crucial than particle kinetics in designing the adsorption column. Decoupling hydrodynamics from the rate processes by filling the bed with fines of an inert material worked well, enabling the breakthrough experiments to be downscaled.

They exhibit a very sharp breakthrough performance, especially in the low-concentration regime, that illustrates the better breakthrough performance of monoliths with respect to shallow carbon packed beds. The low pressure drop of the monolithic system and its excellent performance under discontinuous ow conditions make it an attractive option for gas mask canister applications. A simulation model is presented, including terms of adsorption, di usion and mass transfer. A parametric analysis has been carried out to study the in uence of di erent variables on the breakthrough proÿle. The breakthrough performance is best described by considering a gas velocity distribution over the monolith cross-section. Stacking of the monolithic pieces, increasing cell density, and gas redistribution between pieces reduced this distribution and improved the breakthrough performance. ?

Measurements were performed on two different carbons, Kureha and Sorbonorit B3, in the temperature range between 473 and 700 K. The modelling procedure of the pulse responses consisted of two parts. The transport parameters through the packed bed were determined from the pulse responses of non-adsorbing argon. Adsorption and diffusion parameters were determined for the adsorbing gases n-butane and hexafluoropropylene. As a general rule it is concluded that microporous materials must be described with a basic three-parameter model, while macroporous materials must be described with a simplified two-parameter model. The heats of adsorption, determined from the adsorption equilibrium constant, agree well with the values determined independently from uptake experiments. With Multitrack a single value for the diffusivity is obtained at a given temperature, valid for the low pressure limit, whereas with uptake a range of diffusivities is found, covering a wide concentration range. The values were of the same order of magnitude. Multitrack is a promising method for the simultaneous determination of adsorption and diffusion parameters.

Process operation with these solvents leads to the formation of precipitates during absorption that need to be re-dissolved prior to desorption of CO2. The process configuration is crucial for the successful application of these solvents. Different process configurations have been analyzed in this work, including a full analysis of the baseline operating conditions (based on potassium taurate), the addition of lean vapor compression, multiple absorber feeds, and the use of different amino acids as alternative solvents to the baseline based on potassium taurate. The analysis is carried out with an equilibrium model of the process that approximates the thermodynamics of the solvents considered. The results show that the precipitating amino acid solvents can reduce the reboiler duty needed to regenerate the solvent with respect to a conventional MEA process. However, this reduction is accompanied by an expenditure in lower grade energy needed to dissolve the precipitates. To successfully implement these processes into power plants, an internal recycle of the rich stream is necessary. This configuration, known as DECAB Plus, can lower the overall energy use of the capture process, which includes the energy needed to regenerate the solvent, the energy needed to dissolve the precipitates, and the energy needed to compress the CO2 to 110 bar. With respect to the energy efficiency, the DECAB Plus with lean vapor compression configuration is the best configuration based on potassium taurate, which reduces the reboiler duty for regeneration by 45% with respect to conventional MEA. Retrofitting this process into a coal fired power plant will result in overall energy savings of 15% with respect to the conventional MEA process, including compression of the CO2 stream to 110 bar. Potassium alanate was found to reduce the energy use with respect to potassium taurate under similar process configurations. Therefore, the investigation of potassium alanate in a DECAB Plus configuration is highly recommended, since it can reduce the energy requirements of the best process configuration based on potassium taurate.

In a TAP-like system, called Multitrack, the adsorption of gases on zeolites and microporous carbons has been measured. This paper discusses the experimental procedures and the modeling to obtain the relevant sorption and diffusion parameters. Although this technique is macroscopic, contrary to other macroscopic methods such as thermogravimetrical and chromatographic techniques, the diffusivities obtained are in agreement with those determined using microscopic techniques such as NMR. The model used for the description of the measurements is discussed, together with some model simplifications that can be made for special experimental conditions. Possible extensions to the model are also discussed. Finally, the sensitivity of the method towards parameters like sorption strength, diffusion rates, particles size and occupancy range is discussed. (T.A. Nijhuis) and how to model the experiments accurately to determine the wanted sorption and diffusion parameters.
