Question 1: Design of isothermal reactors 30 Marks The irreversible, gas-phase reaction A+B D is to be carried out in an isotherma °C) plug-flow reactor (PFR) at 5.0 atm. The mole fractions of the feed streams are A 0 B 0.50, and inerts 0.30. The activation energy for the above reaction is 80 000 cal/mol. the pressure drop due to fluid friction in the reactor is so small that it can be ignored, perform the following tasks: 2T a s...

3. The elementary gas-phase reaction A → B + 2C gives a rate constant of 10-4 min-1 at 50°C and has an activation energy of 85 kJ mol1. This reaction is carried out in a flow reactor that is operated isothermally at 127 °C with a negligible pressure drop. The reactor feed is pure A, entering at 127 °C and...

A batch reactor operating at near room temperature, 25°C, is currently taking six hours to reach ninety percent conversion for an irreversible second-order liquid-phase reaction. Account the time to fill, empty, and clean the reactor, this allows one batch to be handled during an ei hour work shift. ing for ght- There is now pressure to cut the reaction time in half, to three hours, so two batches can be handled during a shift. When the reactor temperature is increased...

The elementary reversible reaction A + B 2C occurs in the liquid phase in isothermal CSTR. A stream containing equimolar amounts of A and B in a solvent enters. the reactor, and the conversion of A is measured to be 60%. The equilibrium conversion o A under the same inlet conditions is known to be 80%. The volumetric flowrate into the process is to be...

2. A total of 10000 L/h of metaxylene, C&H(CHs)2, is being isomerized to a mixture of orthoxylene, metaxylene, and paraxylene in a reactor with a volume of 1000 L. The isomerization reaction can be represented as: where A is the metaxylene being fed to the reactor, and B are the different isomers formed. The reaction is being carried out at 400°C and 20 bar. Under these conditions, 35% of the metaxylene fed to the reactor is...
