A non-equilibrium non-isothermal lumped kinetic model (LKM) is analytically and numerically investigated to evaluate the effects of inherent temperature fluctuations in an adiabatic chromatographic column. The model comprises of convectiondiffusion partial differential equations quantifying mass and energy balances in the mobile phase coupled with differential and algebraic equations for mass and energy in the stationary phase. Besides two mass transfer coefficients, two heat transfer coefficients are involved in the model equations. The properties of the considered model are investigated for linear concentration and temperature dependencies of the equilibrium loadings. The Laplace transformation and eigen-decomposition techniques are utilized to solve the set of equations. These solutions are helpful for understanding,

“…The first syngas-to-methanol process was commercialized in 1923, but this process is equilibrium-limited and still suffers from a low single-pass conversion and a low methanol yield. Additionally, the reaction is highly energy-intensive . It has been suggested in the past that the in situ removal of reaction byproducts can increase the single-pass conversion of methanol synthesis using sorption-enhanced reaction processes .…”

A membrane reactor (MR) combines reaction and separation phenomena in a single unit and offers an energy-efficient, cost-effective, compact, modular, and sustainable design compared to conventional designs. A systematic design framework can yield such benefits of MRs and increase their adoption in the chemical process industry. To this end, we present SPICE_MARS (synthesis and process intensification of chemical enterprises involving membrane-assisted reactive separations), a software prototype for conceptual design, simulation, synthesis, and optimization of MRs for different process applications. At the conceptual level, we can determine whether MR is desired or not and select which species to convert/separate. At the equipment level, we obtain optimal MR configurations considering different flow arrangements, intensification strategies, membrane types, sweep gases, reactor lengths, membrane areas, and catalyst amounts. Additionally, we can generate rank-ordered lists of optimal reactor configurations for different design objectives. These enabling capabilities are demonstrated using two case studies involving methanol synthesis and methane partial oxidation. In both cases, novel MR designsachieving drastic improvement compared to current industrial practiceare found.

“…This intensified reaction-separation technology adopts the name simulated moving bed reactor (SMBR). A considerable number of applications have been reported considering SMBRs, among others: enzymatic reaction for higher-fructose syrup production [137][138][139][140], intensified synthesis of fructooligosaccharides [12], esterification from acetic acid and b-phenethyl alcohol to produce b-phenethyl acetate [141] or methyl/ethyl acetate ester from methanol/ethanol [142][143][144], synthesis and separation of methanol from syngas [145], lactosucrose production [146], MTBE synthesis [147], diethylacetal (dimethylacetal) synthesis [148][149][150][151], ethyl lactate synthesis from lactic acid and ethanol [152], biodiesel synthesis [153,154], in situ isomerization and separation of p-xylene [155,156], and, more recently, in the production of single enantiomers [157]. These examples prove the potential of this technique.…”

This work presents a comprehensive insight about simulated moving bed (SMB) technology, from concept to unit operation and process demonstration. A particular relevance is given to SMB nonconventional modes of operation, modeling, and design of SMB-based separations as well as to the construction and operation of SMB units. A conventional separation of a racemic mixture of (S,R)-a-tetralol by means of the FlexSMB-LSRE® unit is addressed to better exemplify a state-ofthe-art SMB lab-scale process development and demonstration.
