A coke oven produces 1000,000 ft3 / h of a gas that has the following composition (% vol): C6H6 8%, C7H8 5%, CH4 40% CO 7%, H2 35% and the rest CO2. The gas leaves the oven at 20 lb / in2 and 740ºF. After cooling to 100ºF, benzene and toluene are removed by 85% by weight by absorption. Determine: (1) Molecular weight of the mixture leaving the oven (2) Flow / mass ratio leaving the oven (3) Composition at the exit of the top absorber of the compounds C6H6, C7H8, CH4, CO2 and CO

Question

A coke oven produces 1000,000 ft3 / h of a gas that has the following composition (% vol): C6H6 8%, C7H8 5%, CH4 40% CO 7%, H2 35% and the rest CO2. The gas leaves the oven at 20 lb / in2 and 740ºF. After cooling to 100ºF, benzene and toluene are removed by 85% by weight by absorption. Determine:

(1) Molecular weight of the mixture leaving the oven

(2) Flow / mass ratio leaving the oven

(3) Composition at the exit of the top absorber of the compounds C6H6, C7H8, CH4, CO2 and CO
