liquid form at the temperature and pressure at which the gas is delivered.

The gas shall in no event contain water vapor in excess of seven (7)

pounds per million standard cubic feet.

 

11.3 Hydrocarbon Dew Point. The hydrocarbon dew point of the gas

delivered shall not exceed twenty degrees Fahrenheit (20øF) at a pressure

of 600 psig.

 

11.4 Total Sulfur. The gas shall not contain more than three-

quarters (0.75) grain of total sulfur per one hundred (100) standard cubic

feet, which includes hydrogen sulfide, carbonyl sulfide, carbon disulfide,

mercaptans, and mono-, di- and poly-sulfides. The gas shall also meet the

following individual specifications for hydrogen sulfide, mercaptan sulfur

or organic sulfur:

 

(a) Hydrogen Sulfide. The gas shall not contain more than

one-quarter (0.25) grain of hydrogen sulfide per one hundred (100)

not exceed more than three-tenths (0.3) grain per one hundred (100)

standard cubic feet.

 

(c) Organic Sulfur. The organic sulfur content shall not

exceed five-tenths (0.5) grain per one hundred (100) standard cubic feet,

which includes mercaptans, mono-, di- and poly-sulfides, but it does not

include hydrogen sulfide, carbonyl sulfide or carbon disulfide.

 

11.5 Oxygen. The oxygen content shall not exceed two-tenths of one

percent (0.2%) by volume and every reasonable effort shall be made to keep

the gas delivered free of oxygen.
