12. GAS QUALITY

12.1 Specifications

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

(7 lbs/MMcf).

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.
