متن کاملControl and Optimization of a Multiple Effect Evaporator
Multiple effect evaporator control is a problem that has been widely reported in the pulp and sugar industries. Evaporators are the largest heat users and major contributors to losses in sugar cane factories. These factors make effective evaporator control crucial to overall factory efficiency. The complexity and large number of interactions make single loop PID control (the conventional propor...
متن کاملA Digital Computer Model of a Multiple Effect Evaporator
A dynamic mathematical model of a multiple effect evaporator has been developed for a digital computer using the IBM Continuous Systems Modelling Program. The model will be incorporated in an overall simulation of a cane sugar factory. The mathematical model was derived from material and energy balance equations assuming that (i) the liquid phase is perfectly mixed; (ii) the vapour phase is alw...
متن کاملDevelopment of an Efficient Linear Model for the Analysis of Multiple Effect Evaporator System
Based on the principles of Process Integration a simplified model has been developed for the analysis of multiple effect evaporator (MEE) systems. It uses the new concepts of stream analysis, temperature path and internal heat exchange for the formulation of the model equations. In addition to it, the above model also takes into account variation in physico-thermal properties as well as boiling...
متن کاملSelection of optimal feed flow sequence for a multiple effect evaporator system
A nonlinear model is developed for a SEFFFE system employed for concentrating weak black liquor in an Indian Kraft Paper Mill. The system incorporates different operating strategies such as condensate-, feed& productflashing and steam& feedsplitting. This model is capable of simulating a MEE system by accounting variations in τ, U, Qloss, physicothermal properties of the liquor, F and operating...
