Natural Gas Dillution?

[wlminex]

I will start this off in Pseudoscience, since that's where (or Conspiracies, or Cesspool) is where some will recommend sending the thread and feedback.

Question: Is it possible for natural gas fuels to be 'diluted' by relatively inert components (e.g., nitrogen, CO2, etc.) in such a manner that the BTU's/unit volume are reduced, causing lower BTU gas mixtures to less efficiently heat homes, etc.? Further, is it possible that natural gas distributors, using such a methodology, might maximize their profits at the expense of users, since user cost is tied to volume usage.

This should be relatively easy to determine using a calorimeter-type instrument to monitor BTUs over an entire year use cycle.

Sure it is possible but it would be obvious to a large part of the gas company what was going on and would be easy to detect. In short it would be incredibly stupid thing to do.

Dilution would generate problems, especially since most gas related equipment is designed to strict specifications. (Namely if gas is being burnt then there will be a set specification designed for a particular gas mix that is designed to be ergonomic and fit the safety protocols applied by an industry standards body)

Variation beyond such defined operating levels to my knowledge would be an extreme no-no in both consumer and industry markets.

If it was "allowed for", then the very equipment would have to be designed with that inclination in mind prior for safety reasons, which in turn would mean it would likely be observed.

Incidentally "Dilution" is often misconstrued as a way to pass emissions tests, as gas readings will give inaccurate ppm of gas contents. You'll be surprised just how many CO2/CH4 emission figures have been "padded" over the years.

I agree . . . . but the OP inferred " is it possible . . . and are "they" doing it for greater profits?" Profit has historically proven to be a great incentive! Perhaps some 'independent' group should try a calorimetric monitoring investigation - should be relatively easy to prove or disprove.

A gas chromatograph could completely analyze the gas in about 15 minutes. Again, the makeup of the gas is so simple to detect that it would be corporate suicide to try to dilute it. You will have to look for another conspiracy, this one just doesn't make sense.
