A3 Dynamic Process Model Analysis

The assignment concerns the extractor of assignments A1 and A2. Only the extraction vessel is considered and some simplifications are made. 

A wastewater flow (the substrate) polluted with aniline is extracted by means of benzene with flow (the solvent). The effective distribution coefficient a depends on the temperature. Steam with flow Fs,eam is added to raise the temperature. The vessel is well mixed by a stirrer with constant speed. The fraction aniline in the wastewater is rednced to Xa. 

Assume that the process can be described by the following equations
