I have a problem.

Reactor is 3 KL

Reaction between A and B in solvent S

A and solvent are in the reactor filled with 50% of the reactor volume.

Heat of rxn is x cal/kg

3 kl reactor have 1.5 kl empty space. reaction at solvent S boiling temp.

no heat removal by jacket. scenario : condenser cooling failure.

Reactor design pr is 6 kg/cm2. and Rupture disc design pressure 2 kg/cm2

Problem: when cooling failure, how many kg of B is required to burst the rupture disc.

How to do this problem.

Ideal gas law we need to use.

[latexman]

Assume adiabatic.  Numerically (spreadsheet) initiate and progress the reaction with material and energy balance until mixture total pressure = RD burst pressure.

hi ,

To support your work , in addition to Latexman's reply , let you get a copy of :

 "Chemical process safety , fundamentals with applications 3rd edition " by Daniel A Crowl and Joseph F Louvar .

 

Hope this is going to help you .

Thanks.

 

Mean I need calculate the pressure inside the vessel by heat generate from the exothermic reaction and the solvent is being boiled up.

 

with available empty space and caudate the p by ideal gas law?

 

am I correct?

Hello ,

To add to my previous email , consider reading the document attached . To me you are going to release a 2 phases mixture through the RD .

 

Hope this is helping you .
