Mathematical modelling of forced circulation evaporator pilot plant

Abstract

Process control, design and optimization are the key features of any industry and continue to improve because of highly increasing global competition. Pilot plant plays a vital role in analyzing the effect of variables at various process conditions and for optimal study of the process. This paper presents nonlinear mathematical model of a laboratory based forced circulation evaporator pilot plant. The modeling is done considering mass balance and energy balance equations. The open loop validation of entire model is done in MATLAB. Various key parameters like level, pressure and composition of material are considered and monitored while modeling. The obtained model was then used as basis for the implementing advanced control strategies, physical study of the pilot plant, controlling plant dynamics etc.
