Abstract:
We present the application of a methodology for process intensification (PI) to generate and identify an improved option for the enzymatic production of biodiesel, whose industrial-scale implementation has not been realized, mainly due to the high cost of the enzyme compared to alkaline catalyst. The problem of synthesis / design is mathematically defined as an optimization problem MINLP (Mixed integer nonlinear problem) whose complexity is increased by the inclusion of a superstructure to generate all the possible options, and hence unsolvable. Therefore, we propose a method of dividing the whole problem into sub-problems. This strategy is included in the PI method, wherein, starting from a base case analysis, limitations are identified and based on them, intensified options are generated. These generated options are evaluated using logical, structural and operational constraints and a generic model represented by a superstructure which includes all the options. The design methodology provided an option for enhanced enzymatic production of biodiesel. With this, the implementation the enzymatic route for biodiesel at commercial scale can be accelerated.
