APPLICATION OF MODIFIED NONLINEAR ORTHOMIN TO CHEMICAL PROCESS SIMULATION

Many process models in chemical engineering consist of a set of non-li near algebraic and transcendental equations. The evaluation of their p erformances require the solution of these equations. This paper illust rates the application of Modified Non-linear Orthomin (MNLOM) for solv ing problems of chemical engineering interest. MNLOM is a recent metho d for solving a system of non-linear equations, in which square of the norm of function vector is minimised in each of the conjugate directi ons. Its success with the problems chosen, particularly from the Chemi cal Kinetics and Reactor Design, signifies positively of its accuracy and robustness. It is our view that MNLOM is a potential method and it should be made use of in Chemical Process Simulation.
