MODELLING AND SIMULATION OF MULTICHANNELENZYMATIC MEMBRANE REACTORS

Enzymatic reactors using immobilized enzymes reactors are usually stirred-tank or packed-bed reactors. However in such reactors the yields can be limited by mass transfer phenomena. In enzymatic membrane reactors (EMRs), the biocatalyst is located on the surface or within the porosity of the membrane and the reaction takes place during the transfer of substrates through membrane pores. Then, mass transfer limitations can be avoided while enhancing the contact between the biocatalyst and the substrates. Indeed, higher yields can be expected. EMRs present additional advantages like operation in continuous mode, relatively easy operation and control and finally straightforward scale-up to large systems. The objective of this work is the employment of computer aided process engineering tools such as modeling and simulation to advance in the knowledge of the performance of enzymatic membrane reactors under different design and operation conditions in three dimensions (3D) model. The model was developed to simulate tubular enzymatic membrane reactors under three different configurations: dead-end, tangential flow with a porous enzymatic membrane and a non-permeable enzymatic wall. The simulations were applied to analyse the influence of reactor configuration, kinetics and mass transport conditions over the reactor performance in order to identify the main aspects to be taken into consideration for attaining optimal designs.
The simulations shown that a non-permeable enzymatic wall configuration seems to be more advantageous than a dead-end configuration with porous membranes in terms of substrate conversion for the studied particular conditions, whereas, the tangential configuration looks more favorable to promote more effectively reacted permeate streams, while only low conversions are attained in the retentate streams. It has been demonstrated that reaction kinetics has the greatest influence among all the analysed variables. Almost total conversion in the permeate stream can be attained for the fastest reactions, while slow reactions suffer from irrelevant conversions.
