A liquid phase reaction A B C takes place in the CSTR. The volume of the solution in the reactor is 5L. The inlet and outlet volumetric flow rates are now constant at qi=q=1 L/min. The reactor is initially filled with a solution that contains A at a concentration CA0=1 mol/L. The inlet and outlet flows then begin. The inlet stream contains A at a concentration
Solve the balance equation for CA(t), and check the solution
Write a balance on species B in the tank and provide an initial condition, and calculate the steady-state concentration of B in the tank (t∞), CBS.
The liquid phase suspension polymerisation reaction of methyl methacrylate monomer to polymethyl methacrylate (MMA PMMA) or AP, takes place in a 10L batch reactor. The initial reaction mixtures consists of monomer drops dispersed in water. The monomer volume fraction in the reaction mixture is 0.6. The polymerisation occurs in the drops The liquid reactant A has a density of 0.9g/ml. The product of the reaction P is solid in the form of particles and has a density of 2.5g/ml. During the course of the reaction the density of the reaction mixture and hence the volume change. Calculate the volume in the system at the end of the reaction for 80% conversion. What is the volume change?
