Recent threads have debated the safety of different fuel gases and
the “cleanliness” of acetylene but here’s a different twist to the
discussion of fuel gas - does anyone care about the carbon emissions
of these gases?
Per 1 million BTUs propane adds 139 pounds of carbon into the
atmosphere; for acetylene it is 159 pounds and for natural gas it is
117 pounds. This website will show you the source of the propane and
natural gas data http://www.eia.doe.gov/oiaf/1605/coefficients.html
and I’ve calculated the acetylene number (write to me privately if
you want the math).
How much gas is 1 million BTUs? You would have to use 46 pounds of
propane, 680 cubic feet of acetylene or 1,000 cubic feet of natural
I am asking the question because my company, G-TEC Natural Gas
Systems, sells torch boosters into many industries and we are
starting to get questions about greenhouse gases, especially in
southern California. Some municipalities are changing their
purchasing behavior to favor gases with lower carbon emissions.
Jewelers’ torches may use very little gas and add little carbon to
the atmosphere at a time, but over time CO2 adds up. So I am curious
to ask if, knowing these numbers, it is something you would find
important or consider when choosing a fuel gas.
