Initially reactant A is fed to the reactor and B is added to it
semi-batchwise once A reaches the reaction temperature
of 90℃
Let us look at the process flow diagram:
4. PROCESS DETAILS
Conventional
Process
•10 tonnes of A is taken in the reactor
•Temperature of the reactor = 90℃
•Rate of Addition of B : 2 tonne/hr for 10 hrs
•Holding time : 10 hrs
•CURRENTTURNOVER: 352.49 Cr/year
•Current profits : 358.97 Cr/year

PROFITS! ☹️
5. HERE COMES A CHEMICAL ENGINEER!
• With the help of python programming we can optimize the process
parameters such as :
Optimization
Parameters
•Dosing time and holding time
•Heat transfer characteristics
6. WHAT CAN BE DONE?
• By introducing heat effects in the current process we can obtain
the right amount of coolant water flowrate and right area of
condenser required.
• We can optimize the holding time and the dosing time of the
process.
• By such optimization the operating costs will be minimized.
• Regular maintenance of all the equipments used and
continuous monitoring of the market value of the equipments
will minimize the fixed costs.
