Abstract
Due to multi input multi output variables affected the continuous stirred tank reactor its worthy to use the state space model to study the dynamics of this system. In this work, a saponifecation process was studded on which Ethel acetate was reacted with sodium hydroxide to produced sodium acetate and ethanol. one litter operation volume CSTR was used, the flow rate of Ethel acetate and cooling water were toke as disturbance variables and the concentration of sodium acetate and the temperature of reactor as response variables. The results show improvement compared with linearized model.
Highlights
Continuous stirred tank reactors (CSTR) are the most basic of the continuous reactors used in chemical processes
Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time
State equations may be obtained from an nth order differential equation or directly from the system model by identifying appropriate state variables
Summary
Continuous stirred tank reactors (CSTR) are the most basic of the continuous reactors used in chemical processes. State equations is a description which relates the following four elements: input, system, state variables, and output. Systems were represented in the time domain by a type of differential equation called a state equation.
