  Question 1

You are working with a chemical process in your factory with a

TUBULAR reactor in ISOTHERM conditions.   cubic meter
  The conversion of compound A at the outlet of your reactor has a value of 50 %.         kilograms per hour
                      kilograms
  The reaction mechanism of your reaction is A + B D                
  The reaction rate equation for this reaction is:
               
  This reaction rate can be writen as a function of conversion of A as:                
   
           
  In which: a = 2                
    b = 1.6                
   
 
                 
    EA (kJ kmol-1) = 7000                
   
 
                 
  OTHER DATA:                    
  Initial volumetric flow = 10 cubic meter per hour
760 kJ kmol-1        
  mass flow = 10000 kilograms per hour
9.8 kJ kg-1 K-1        
  CA,0 = 100   Temperature in the reactor = 20 ᵒC    
  CB,0 = 600                  
                       
                A) Evaluate the overall order of reaction and the units of the rate constant        
               B) Calculate the HEAT FLOW TO EXCHANGE for your operation conditions        
               C) Calculate the VOLUME OF YOUR REACTOR for your operation conditions        
                D) Demonstrate graphycally what is the best configuration to work in continuous for your thermal operation conditions and final conversion
                     (If your best configuration consists in more than one reactor, specify the conversion at the exit of each reactor).
   Question 2          

 

 

         
                       
You are working with a chemical process in your factory with a BATCH reactor in ISOTHERM conditions.   cubic meter
The conversion of compound A at the outlet of your reactor has a value of 50 %.         kilograms per hour
                    kilograms
The reaction mechanism of your reaction is A + B D                
The reaction rate equation for this reaction is:
               
This reaction rate can be writen as a function of conversion of A as:                
 
           
In which: a = 2                
  b = 1.4                
 
 
                 
  EA (kJ kmol-1) = 5000                
 
 
                 
OTHER DATA:                    
Volume of reaction = 10 cubic meter
-730 kJ kmol-1        
Total mass = 10000 kilograms
2.5 kJ kg-1 K-1        
CA,0 = 400   Temperature in the reactor = 90 ᵒC    
CB,0 = 500                  
                   
              A) Evaluate the overall order of reaction and the units of the rate constant        
             B) Calculate the HEAT TO EXCHANGE for your operation conditions        
             C) Calculate the TIME OF REACTION REQUIRED for your operation conditions        
              D) Demonstrate graphycally what is the best configuration to work in continuous for your thermal operation conditions and final conversion
                   (If your best configuration consists in more than one reactor, specify the conversion at the exit of each reactor).
