A simulated annealing-based algorithm (MSIMPSA) suitable for the optimization of mixed integer non-linear programming (MINLP) problems was applied to the synthesis of a non-equilibrium reactive distillation column. A simulation model based on an extension of conventional distillation is proposed for the simulation step of the optimization problem. In the case of ideal vapor}liquid equilibrium, ...

Furfural is only derived from lignocellulosic biomass and an important chemical used in the plastics, agrochemical, pharmaceutical industries. The existing industrial furfural production process, involving reaction purification steps, suffers a low yield intensive energy use. Hence, major improvements are needed to sustainably upgrade process. In this study, conventional process based on contin...

Emulsion-enhanced biphasic esterification has proven to be applicable for carboxylic acid recovery from dilute aqueous process streams. The is esterified with 1-octanol in an emulsified regime 4-dodecylbenzenesulfonic (4-DBSA) or Ni(DBSA)2 as catalyst. After phase separation, the laden solvent must regenerated. This study presents a regeneration concept based on reactive distillation transester...

This research presents a new study in reactive distillation by adopting consecutive reaction . The adopted was the saponification of diethyl adipate with NaOH solution. occurs two steps. process had role withdrawing intermediate product i.e. monoethyl from reacting mixture before second conversion to disodium occurred. It found that appeared successfully distillate liquid. percentage di-ester m...
