Abstract: In order to reduce the energy consumption of the concentrating the black liquor in Kraft recovery process in paper mill, a mathematical models is developed and proposed for the analysis of multi stage evaporator (heptad’s effect evaporator system). These multistage evaporator is modeled based on the flow of black liquor and steam operation option. In the present study, live steam split, liquor feed split, pre-heaters and hybrid of these energy saving scheme are coupled with backward, forward and mixed feed multi stage evaporator system. The systematic material balance and heat balance equations are described as the form of matrix equation to realize the generality of the mathematical models. The advantage of these models are its simplicity, representation of equations in matrix form and linearity. The proposed mathematical models can be easily solved by numerical methods combining with the iteration method, which has one more advantages of less sensitive to its initial values, high convergence speed and stability. The developed models can also be easily simulate under different operating strategies once knowing the liquor, steam and effects parameters. © Springer Science+Business Media Singapore 2016.
