Answer 1

Final Volume = V2 = 2 m^3

Final Pressure =  50 kPa

Calculate the final volume and pressure

The theory used in this question is the Ideal Gas Law, PV=nRT, which states that the product of the pressure and volume of a gas is equal to the number of moles of the gas times the gas constant times the temperature.

This law is used to calculate the temperature, pressure and volume of the air at each step of the process.

Initial Volume = V1 = 1 m^3

Process 1: Constant Pressure (Isothermal)

Heat added = Q1 = Cp(T2 - T1)

        = 1.00 kJ/kg.K * (300K - 300K)

        = 0 kJ/kg

Final Volume = V2 = 2 m^3

Process 2: Constant Volume (Isochoric)

Heat removed = Q2 = Cv(T3 - T2)

          = 0.718 kJ/kg.K * (T3 - 300K)

Rearranging the above equation, we get

T3 = 300K + (Q2/0.718 kJ/kg.K)

Final Pressure = P2 = P1/2

          = 100kPa/2

             = 50 kPa

The reaction effluent goes to a condenser from which two streams emergers a liquid product stream containing essentially all of the methanol formed in the reactor, and a gas stream containing all of the CO, H2 leaving the reactor.

What a methanol synthesis loop with a stoichiometric feed?

A methanol synthesis loop with a stoichiometric feed of CO and H2 is to be designed for 95% overall conversion of CO. All the methanol formed leaves in the product stream.

Not more than 2% of the CO and 0.5% of the H2 emerging form the reactor is to leave in the product stream- the remainder is recycled.

Therefore, The reaction effluent goes to a condenser from which two streams emergers a liquid product stream containing essentially all of the methanol formed in the reactor, and a gas stream containing all of the CO, H2 leaving the reactor.
