Interpretation Introduction
Interpretation:
The flow rate of air and the percentage of oxygen in the product stream should be calculated.
Concept introduction:
It is given that in order to ignite an air and methane mixture the mole percentage of methane should be between 5% to 15%.
A mixture containing 9 mole% methane should be reduced to lower flammability limit by introducing air at a rate of 700 kg/h.
In addition, Assume that,
Air is consisted of 21 mole% O2 and 79% N2
The average molecular weight of air is 29 g/mol.

A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. A mixture containing 9.0 mole% methane in air flowing at a rate of 7:00 x 102 kg/h is to be diluted with pure air to reduce the methane concentration to the lower flammability limit. Calculate the required flow rate of air in mol/h and the percent by mass of oxygen in the product gas. (Note: Air may be taken to consist of 21 mole% O2 and 79% N2 and to have an average molecular weight of 29.0.)
A steady-state process to recover crystalline potassium chromate (K,CrOz) from an aqueous solution of this salt
is required. Four thousand kilograms per hour of a solution that is one-third K,CrO, by mass is joined by a recycle
stream containing 36.4% K2CrO7, and the combined stream is fed into an evaporator. The concentrated stream
leaving the evaporator contains 49.4% K,CrO; this stream is fed into a crystallizer in which it is cooled (causing
crystals of K,CrO, to come out of solution) and then filtered. The filter cake consists of K,CrO, crystals and a
solution that contains 36.4% K,CrO, by mass; the crystals account for 95% of the total mass of the filter cake. The
solution that passes through the filter, also 36.4% K,CrO,, is the recycle stream.
1- Draw the flowchart of the system and put all known information.
2- Calculate the rate of evaporation, the rate of production of crystalline K,CrO7, the feed rates that the
evaporator and the crystallizer must be designed to handle, and…
