Relation of The Term GPM To The Hydrocarbon Dew Point
In the United States, the hydrocarbon dew point of processed, pipelined natural gas is related to and characterized by the term GPM which is the gallons of liquifiable hydrocarbons contained in 1,000 cubic feet (28 m3) of natural gas at a stated temperature and pressure. When the liquifiable hydrocarbons are characterized as being hexane or higher molecular weight components, they are reported as GPM (C6+).
However, the quality of raw produced natural gas is also often characterized by the term GPM meaning the gallons of liquifiable hydrocarbons contained in 1,000 cubic feet (28 m3) of the raw natural gas. In such cases, when the liquifiable hydrocarbons in the raw natural gas are characterized as being ethane or higher molecular weight components, they are reported as GPM (C2+). Similarly, when characterized as being propane or higher molecular weight components, they are reported as GPM (C3+).
Care must be taken not to confuse the two different definitions of the term GPM.
Although GPM is an additional parameter of some value, most pipeline operators and others who process, transport, distribute or use natural gas are primarily interested in the actual HCDP, rather than GPM. Furthermore, GPM and HCDP are not interchangeable and one should be careful not to confuse what each one exactly means.

Famous quotes containing the words relation, term, dew and/or point:
“... a worker was seldom so much annoyed by what he got as by what he got in relation to his fellow workers.”
—Mary Barnett Gilson (1877–?)
“In eloquence, the great triumphs of the art are when the orator is lifted above himself; when consciously he makes himself the mere tongue of the occasion and the hour, and says what cannot but be said. Hence the term abandonment, to describe the self-surrender of the orator.”
—Ralph Waldo Emerson (1803–1882)
“When we awoke, we found a heavy dew on our blankets. I lay awake very early, and listened to the clear, shrill ah, te te, te te, te of the white-throated sparrow, repeated at short intervals, without the least variation, for half an hour, as if it could not enough express its happiness. Whether my companions heard it or not, I know not, but it was a kind of matins to me, and the event of the forenoon.”
—Henry David Thoreau (1817–1862)
“All people who have reached the point of becoming nations tend to despise foreigners, but there is not much doubt that the English-speaking races are the worst offenders. One can see this from the fact that as soon as they become fully aware of any foreign race they invent an insulting nickname for it.”
—George Orwell (1903–1950)
