Theoretical Air Requirement Solution

STEP 0: Pre-Calculation Summary

Formula Used

Theoretical Air Requirement = Theoretical Oxygen Demand/0.21
Air_Theoretical = O₂Demand/0.21
This formula uses 2 Variables

Variables Used

Theoretical Air Requirement - (Measured in Mole) - Theoretical Air Requirement is defined as the minimum amount of air which will allow the complete combustion of the fuel is called the Theoretical Air (also referred to as Stoichiometric Air).
Theoretical Oxygen Demand - (Measured in Mole) - Theoretical Oxygen Demand is defined as required moles of Oxygen for complete combustion of all the fuel based on stoichiometry to produce Carbon dioxide.

STEP 1: Convert Input(s) to Base Unit

Theoretical Oxygen Demand: 12 Mole --> 12 Mole No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Air_Theoretical = O₂Demand/0.21 --> 12/0.21

Evaluating ... ...

Air_Theoretical = 57.1428571428571

STEP 3: Convert Result to Output's Unit

57.1428571428571 Mole --> No Conversion Required

FINAL ANSWER

57.1428571428571 ≈ 57.14286 Mole <-- Theoretical Air Requirement

What is Chemical Plant?

A chemical plant is an industrial process that manufactures chemicals, usually on a large scale. The general objective of a chemical plant is to create new material wealth via the chemical or biological transformation and/or separation of materials.

What is Chemical Process?

A chemical process is generally understood to be any discernable portion of chemical manufacturing during which feedstocks are acted upon to introduce a chemical change to the feedstock in order to convert it to a desired product.
