The process consists of two unit operations, a reactor and a separator. The process takes in some flow rates A1 and B1 of species A and B. The reactor has a reaction that produces an intermediate product C that then needs to be converted to the desired product D by a second reaction.

Question

The process consists of two unit operations, a reactor and a separator. The process takes in some flow rates A1 and B1 of species A and B.

The reactor has a reaction that produces an intermediate product C that then needs to be converted to the desired product D by a second reaction.

A + B → C (Reaction 1)

A + C → D (Reaction 2)

 

The single-pass conversion of the reactor is 90% with a 30% selectivity for Reaction 2.

The products of the reaction in stream “2” are fed to a separator, which produces the product stream “3” and a recycle stream “4.”

The specifications of the separator are a recycle of 65% of D and 85% of C.

The flow B2 is evenly split between the product and recycle streams, while 10% of A2 is lost to the product stream.

Set up all relevant mass balances then develop the numerical methods required to study the output stream as a function of the inlet flow rates A1 and B1.

Briefly discuss your plan below. 

A₁, B₁
A+B → C
A+ C

A2, B2, C2, D2
A4, B4, C4, D4
A3, B3, C3, D3.
