Best answer

The correct option is (d) 4

The best explanation: We can write 4 balance equations: A total balance equation and 3 component balance equations.

Independent balances: Not all balances are independent since the total balance is the sum of all of the component balances.

Thus, the number of independent balances we can write = the number of components.

A continuous process is set up for treatment of wastewater. Each day, 10^3 kg cellulose and 10^5 kg bacteria enter in the feed stream, while 10^2 kg cellulose and 1.5 x 10^2 kg bacteria leave in the effluent. The rate of cellulose digestion by the bacteria is 8 x 10^2 kg d^-1. The rate of bacterial growth is 4x 10^2 kg d^-l; the rate of cell death by lysis is 6 x 10^2 kg d^-1. Write balances for cellulose and bacteria in the system.

The fresh feed to an ammonia synthesis reactor contains nitrogen, hydrogen and 2.0 mole per cent inerts. The molar ratio of H2:N2 is 3:1. The product stream consists of pure ammonia. Since conversion in the reactor is only 15%, a recycle stream is used and in order to avoid build-up of inerts, a purge stream is withdrawn. The rate of purge stream is adjusted to keep inert concentration in the recycle stream at 8 mole per cent. For a fresh feed rate of 100 moles/hr. Note that recycle stream contains only nitrogen, hydrogen and inerts. The N2:H2 ratio of 1:3 is maintained in every process stream, and calculate the number of moles, moles of inerts and moles of hydrogen in the recycle stream?
