It could be single effect or multiple effect evaporators. Evaporators are used in many process industries such as pharmaceuticals, dairy and food processing, paper and pulp industry, etc. Caustic soda industry is considered with four effect falling film evaporator. There is a forward feed flow pattern. Designing of this system has been done. In this paper description of steady state model of multiple effect evaporator is described for simulation purpose. The steam economy of each effect is in increasing order. This model includes overall and component mass balance along with energy balance equations to estimate product and evaporation rate in each effect which will help to find required area for each effect for forward feed flow. The effect of feed rate increment and effect number has also been discussed. The code has been developed by using MATLAB. Results of the present approach are validated with industrial data.
