Within a process plant, a stream consisting of a mixture of components A and B (stream 1) is mixed with a stream of pure component B (Stream 2) in a process vessel called a mixer. Stream 1 is 50 mass% B. The outlet stream of the mixer (stream 3) is 40 mass% A. Stream 3 is fed into a separator which brings the mixture to equilibrium at 70°C and 1atm. Within the separator, the mixture forms two separate phases. The less dense phase exits the separator in stream 4 and the more dense phase exits the separator in stream 5. The processes operate at steady state, and no reactions happen in either process vessel. A process known compositions and flow rates labeled. A temperature- composition diagram for mixtures of A and B at 1 atm is agram is shown below, with available below. What is the mass fraction of B in stream 4? a. b. What is the total mass flow rate of the stream 4? What is the mass flow rate of B in stream 4? с. d. Write a mass balance equation for component B in the mixer e. What is the total mass of B entering the mixture every hour in Stream 2
