I mostly need help setting up what two equations I need to use

A liquid feed stream (F, 200 kg/h) mixture containing 25% benzene and 75% toluene by weight enters a distillation column. The column produces two product streams (D and B). The product leaving the top of the column (D) is 98% benzene by weight, and contains 95% of all the benzene leaving the system. Write a system of two linear algebraic equations to solve for the mass flow rate of stream D, as well as the mass flow rate leaving the bottom of the column (B).

(Note: this will first require you to develop an expression for the mass fraction of benzene in stream B.)

(a) Solve this system of equations using Excel with the associated matrix math operations. Display your Excel calculations in your submission.

(b) Solve this system of equations using Polymath, and include the Polymath Report.

(c) What is the mass fraction of benzene in stream B?

    4.6. A distillation column is a process unit in which a feed mixture is separated by multiple partial vapor- izations and condensations to form two or more product streams. The overhead product stream is rich in the most volatile components of the feed mixture (the ones that vaporize most readily), and Equipment Encyclopedia distillation column the bottom product stream is rich in the least volatile components. The following flowchart shows a distillation column with two feed streams and three product...

    Toluene + H2 → Benzene + CH4 Two streams enter the process. The first input stream is pure liquid toluene, which enters at a rate of 40 mol/s. The second input stream is a mixture of H2 (95 mole%) and CH4 (5 mole%). The flow rate of H2 in the second stream is equal to 200 mol/s. Two streams leave the process. The first output stream contains only liquid benzene (product) and toluene (unconverted reactant). The second output stream contains...

    QUESTION 5 A distillation column has one inlet feed (F), and two outlets, a distillate (D) and a bottom (B) stream. The inlet feed, F = 100 kg/h, of ethanol and water, has an ethanol mass fraction of xF = 0.5. The distillate flow rate is 85 kg/h, and the bottom ethanol mass fraction is xB = 0.38. What is the total bottom flow rate, B, in kg/h?
