12. GAS QUALITY
All gas received by Sabine from Shipper shall conform to the
following quality specifications:
a) Heating Value. The gas shall have a heating value of
not less than nine hundred seventy Btus per standard
cubic foot (970 Btus/Scf).
b) Water Vapor. The gas shall not contain more than
seven pounds of water per million standard cubic feet
c) Oxygen. The gas shall not contain more than two-
tenths of one percent (0.2%) by volume of oxygen.
d) Carbon Dioxide and Nitrogen. The gas shall not
contain more than three percent (3%) by volume of a
combined total of carbon dioxide and nitrogen.
e) Hydrogen Sulfide. The gas shall not contain more than
one-quarter grain of hydrogen sulfide per one hundred
standard cubic feet (1/4 gr/100 Scf).
f) Mercaptans. The gas shall not contain more than one-
quarter grain of mercaptans per one hundred standard
cubic feet (1/4 gr/100 Scf).
g) Total Sulfur. The gas shall not contain more than
five grains of total sulfur per one hundred standard
cubic feet (5 grs/100 Scf).
h) Dust, Gums and Solid Matter. The gas shall be
commercially free from dust, gums, gum-forming
constituents, and other solid matter.
i) Liquid Hydrocarbons. The gas shall be free of
hydrocarbons in liquid form at the temperature and
pressure at which the gas is received, as determined
by using the Peng-Robinson equation of state to
calculate a hydrocarbon dew point temperature of the
gas and assessing whether liquids will drop out once
the gas is received into the pipeline under existing
pipeline conditions, i.e., when the dew point
temperature of the gas when received by the pipeline
is higher than the temperature of gas in the pipeline.
