Energy measurement using flow computers and chromatographs

摘要

The natural gas industry is changing from a measurement system based on volume to one based on a volume of energy. As the natural gas commodity is passed from producer to the final delivery customer it is mixed with other produced gases of different energy values causing the final product to be very different from it's original composition. This created a difference between state and federally regulated movement of natural gas. To remove inequities in measurement terms, the Natural Gas Policy Act of 1978 was passed which included as one of it's provisions that natural gas was to be bought and sold on the basis of energy content.
