This contribution describes the influences of the reaction trays and feed-inlet locations of the RD column on the simulation results.
Remarkable, the results show that the optimum number of reaction trays is 17 and introducing both feeds to the 13th stage leads to a minimum energy demand.
This contribution explores feasibility of using the reaction in the RD column and also describes the influence of reflux ratio, reaction trays, operating pressure and feed inlet locations of the RD column in simulation environment.
Impacts of three parameters, including reactant flow rate, reaction trays, and feed-inlet location on the temperature profile and component compositions in the columns are investigated to achieve an optimum condition of the process in terms of energy demand.
A mathematical model of a reactive distillation column, which takes into account chemical equilibrium, kinetics of liquid phase catalysed reaction and tray efficiency, has been developed.
The design of the trays is tested to ensure that no operational issues, such as flooding or weeping, occur, and that the reaction is homogeneous along the tray.
The proposed formulation uses disjunctions for conditional trays to apply the MESH and reaction kinetics equations for only the selected trays in order to reduce the size of the nonlinear programming subproblems.
Sieve tray columns for gas liquid reactions sometimes operate at liquid depths much greater than in conventional distillation columns.
The results show that the optimized objective function values are very similar, and mostly independent of the number of trays and of the reaction distribution.
Solution of the model yields the optimal feed tray locations, number of trays, reaction zones, and operating and design parameters.
