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.

  PFR_2_3 ……………………Reaction1

  PFR_2_4…………………………Reaction2

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

  PFR_2_7

  PFR_2_8

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.
