Question

A gas conatins 75.0wt% methane, 10.0% ethane, 5.0% ethylene, and the balance water

a) calculate the molar composition of this gas on both wet and dry basis and the ratio (mol h2o/mol dry gas)
b ) if 100kg/h of this fuel is to be burned with 30% excess air, what is the required air feed rate (kmol/h)? how would the answer change if the combustion were only 75% complete?

Answer 1

Step-by-step explanation:

The concept of material balance on wet and dry basis is applied and the detailed analysis and calculations is as shown in the attached files.
