1.Kinetic Reactor

Sodium acetate is prepared in a continuous reactor from the reaction of sodium hydroxide and ethyl acetate.

Sodium hydroxide and ethyl acetate are fed to the reactor at a concentration of 0.10 mol/L, a temperature of 30 °C and a pressure of 101325 Pa.  The rate constant is 0.138 liter/mole*s. The volume of the reactor is 1L and the total feed flowrate is 0.086892 mol/s. Simulate the kinetic reactor and determined the outlet composition at steady state.

2. Stoichiometric Reactor

Problem Statement:

Reaction:

Decomposition of di-t-butyl peroxide (DTBP) to acetone and ethane

Reaction kinetics:

Reaction conditions:

Temperature 154.6 ^oC

Pressure 491.8 mmHg

Feed and feed conditions:

100 kmol/h of (DTBP) at 110 ^oC and 760 mmHg

Information for steady state:

1. Reaction is isothermal
2. Conversion with respect to DTBP is 85 %
3. Reference temperature for heat of reaction is 25 ^oC

Perform a stoichiometric reactor simulation to determine the heat of reaction and the steady-state mole rates of components in the product stream.

3.Plug Flow Reactor with Multiple Reactions

THE PROBLEM STATEMENT

Allyl chloride is to be produced in a 12-ft. long 2-in ID tube operating at isothermal PFR. The feed is a 4:1 molar ratio of propylene to chlorine and enters at a feed rate of 0.85 lbmole/hr and 2 atm of pressure and temperature of 1000 Rankine. The reactor pressure is assumed to be constant.

The rate constants have units of lbmoles/(hr-ft³-atm²) and are:

where T is in degrees Rankine and R is in Btu/(lbmole ºR). The rate expressions are

Calculate

1)  The exiting stream concentrations from the reactor.

2)  Plot the change in concentration of the reactants and products along the volume of the reactor.
