1.13 The term "Gross Heating Value" shall mean the number of
Btu's liberated by the complete combustion at a constant
pressure, of one (1) cubic foot of gas, at a base temperature of
sixty degrees (600) Fahrenheit and a referenced pressure base of
fourteen and seventy-three hundredths ( 14.73) pounds per square
inch absolute, with air of the same temperature and pressure of
the gas, after products of combustion are cooled to the initial
temperature of the gas, and after the water of the combustion is
condensed to the liquid state. The Gross Heating Value of the
gas shall be corrected for the water vapor content of the gas
being delivered; provided, however, that if the water vapor
content of the gas is seven (7) pounds or less per one million
(1,000,000) cubic feet, the gas shall be assumed to be dry and no
correction will be made.
QUALITY OF GAS
2.1 All gas delivered by Shipper (or its designee) to
Caprock at the Delivery Point shall conform to the following
(A) Water Vapor: The gas shall in no event have a
water vapor content in excess of seven (7) pounds of water
vapor per million (1,000,000) cubic feet of gas measured at
a pressure base of fourteen and seventy-three hundredths (
14.73) psia and at a temperature base of sixty degrees (600)
(B) Hydrogen Sulfide: The gas shall not contain more
than one quarter (0.25) grain of hydrogen sulfide per
hundred (100) cubic feet.
(C) Total Sulphur: The gas shall not contain more than
two (2) grains of sulfur per one hundred (100) cubic feet of
(D) Mercaptans: The gas shall not contain more than
five (5) parts per million (PPM) by volume of mercaptan.
(E) Temperature: The gas shall not have a temperature
of less than forty degrees (400) Fahrenheit, nor more than
one hundred twenty degrees (1200) Fahrenheit.
(F) Carbon Dioxide: The gas shall not contain in
excess of two percent (2%) by volume of carbon dioxide.
(G) Oxygen: The gas shall not contain in excess of
five (5) parts per million (PPM) by volume of oxygen.
(H) Nitrogen: The gas shall not contain in excess of
two percent (2%) by volume of nitrogen.
