How Do You Calculate Stoichiometric Coefficients in Natural Gas Combustion?

Click For Summary

Discussion Overview

The discussion focuses on calculating stoichiometric coefficients in the combustion of natural gas, specifically involving a reaction with multiple components. Participants explore the equations needed for balancing the reaction and the assumptions involved in the analysis.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant presents a combustion reaction involving various components of natural gas and attempts to derive equations based on mass conservation.
  • The participant notes that they have derived five equations but believes they need seven to solve the system, indicating a potential gap in information about the products of the reaction.
  • Another participant questions the term "moral analysis" in the context of the gas, seeking clarification on its meaning.
  • There is a suggestion that the right-hand side of the reaction equations are constants, which may imply a misunderstanding or simplification of the problem.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are questions raised about terminology and the adequacy of the equations presented. The discussion remains unresolved regarding the calculation of stoichiometric coefficients.

Contextual Notes

The discussion lacks clarity on the definitions used, particularly regarding "moral analysis," and there are unresolved assumptions about the products of the combustion reaction.

I had a question on how to find the stoichimoteric coefficient in combustion reaction contains several types of natural gas.

Lets say for example: u start with a natural gas (using moral analysis) 0.865CO2 + a0.08C3H8 + b0.02C3H8 c0.035N2 + d(O2 + 3.76) ------> eCO2 + fH20 + gN2;

Using conseration of mass i get 4 equations + assume that i am start with one mole (0.865 + 0.08a + b0.02 + c0.035 = 1

that give me 5 equations but i need 7 equations to solve. We are told nothing about the end product, expect that it goes to completion with expess air.



Could some please help me?
