Information The first order isomerisation reaction A --> B is to be carried out in a perfectly mixed single CSTR. The contents are to be maintained at 436K using coiling coils. However the feed stream of component A (liquid) is supplied at 293K. The densities of A and B at 436K are each 900 kg m-3 and their heat capacities and relative molecular weights are 0.525 kJ mol- 1K 250 respectively. The rate constant (k436) at 436K = 0.80h-1. An annual production rate of B of 106 Kg is required at a conversion of 0.97. find the following: - (A) The liquid hold up in the tank, Vr (B) The heat load on the cooler if the plant is to be operational for 8000h in the year. Steps to include: Material balance of a CSTR. Calculate the mean residence time t. Calculate the volumetric flowrate UO. Calculate the volume, Vr, of the reactor. Calculate the heat duty on the cooler.

Transcribed Image Text:Information
The first order isomerisation reaction A --> B is to be carried out in a perfectly mixed single
CSTR. The contents are to be maintained at 436K using coiling coils. However the
feed
stream of component A (liquid) is supplied at 293K. The densities of A and B at 436K are
each 900 kg m-3 and their heat capacities and relative molecular weights are 0.525 kJ mol-
1K
250 respectively. The rate constant (k436) at 436K = 0.80h-1. An annual production rate of B
of 106 Kg is required at a conversion of 0.97.
find the following: -
(A) The liquid hold up in the tank, Vr
(B) The heat load on the cooler if the plant is to be operational for 8000h in the year.
Steps to include:
Material balance of a CSTR.
Calculate the mean residence time t.
Calculate the volumetric flowrate u0.
Calculate the volume, Vr, of the reactor.
Calculate the heat duty on the cooler.
