Calculating Synthesis Gas Volume for Water Heating: A Combustion Problem

Click For Summary
SUMMARY

The discussion focuses on calculating the volume of synthesis gas required to heat 45.0 gallons of water from 16.0°C to 60.0°C using the combustion of a gas mixture consisting of 55.0% CO and 33.0% H2. The key equation involved is Q = mcΔt, where Q represents the heat energy required, m is the mass of water, c is the specific heat capacity, and Δt is the temperature change. Participants emphasize the necessity of consulting combustion heat tables for CO and H2 to determine the energy output from the synthesis gas during combustion.

PREREQUISITES
  • Understanding of thermodynamics and heat transfer principles
  • Familiarity with the specific heat capacity of water
  • Knowledge of combustion reactions and stoichiometry
  • Ability to interpret data from combustion heat tables
NEXT STEPS
  • Learn how to apply the Q = mcΔt equation in practical scenarios
  • Research the combustion heat values for CO and H2
  • Study the properties and applications of synthesis gas in energy production
  • Explore the calculation of gas volumes at standard temperature and pressure (STP)
USEFUL FOR

Chemical engineers, energy analysts, students in thermodynamics, and anyone involved in combustion processes or energy calculations.

Homework Statement

The partial burning of coal in the presence of O2 and H2O produces a mixture of CO(g) and H2(g) called synthesis gas. This gas can be used to synthesize organic compounds, or it can be burned as a fuel. A typical synthesis gas consists of 55.0% CO(g), 33.0% H2(g) and 12.0% noncombustible gases (mostly CO2(g)), by volume.

Homework Equations



What volume of the synthesis gas, measured at STP and burned in an open flame (constant-pressure process), is required to heat 45.0 gal of water from 16.0 to 60.0 C? (1 gal=3.785 L.)

The Attempt at a Solution



I have no idea how to solve this. the only thing i was able to find was Q (q=mcΔt). but idk how to find volume from there.

Thanks!

I guess you need to check tables for combustion heat of CO and H2.
