    PROBLEM STATEMENT

    Sodium acetate is being prepared by the following reaction in a batch reactor.

     NaOHCHCOOCHCHOHCHCOONa;;;253253

    Sodium Hydroxide and ethyl acetate are fed to the reactor at a concentration of 0.1M as an initial charge at 25 C and 101325 Pa. The rate constant is 0.104sec*ltr/mole. Simulate the dynamic batch reactor for 30 minutes and plot the change in concentration of NaOH as it changes with time.

Procedure:

Step 1: Creating the flow sheet

    Step 2: Entering the components and formatting engineering units Step 3: Entering the reactor specs

    Step 4: Running the DYNAMIC simulation

    Step 5: Retrieving the results

Step 1: Creating the flow sheet

    Select and right click on the batch reactor icon (i.e. second row, fifth element) on the workspace. Next click on the change mode bar to change from flowsheet mode to simulation mode to specify the system.

Step 2: Entering the components and formatting engineering units

Go to the Thermophysical on the menu bar and click on Components List. Find sodium

    hydroxide, ethyl acetate, sodium acetate, ethanol and water from the CHEMCAD components list and add them to the component list.
