GENERAL TERMS AND CONDITIONS

Section 3

(Continued)

 

3.5 Basis - Volumes delivered shall be corrected for deviation from

Boyle's Law at the pressures and temperatures under which gas is

measured by use of the NX-19 formula or table appearing in the

manual entitled "PAR Research Project NX-19, Extension of Range of

Supercompressibility Tables," AGA Catalogue No. 48/PR, published

by the AGA in 1963, including any subsequent amendments or

revisions which meet generally accepted industry standards and

practices and are acceptable to Gulf South and Customer.

 

3.6 Determination of Heating Value - The heating value of the gas

shall be determined by a chromatograph, continuous sampler, spot

sample, or calorimeter. The method to be employed shall be

selected by Gulf South and shall meet generally accepted industry

standards and practices. The arithmetical average of the heating

value recorded during periods of flow by a chromatograph or

calorimeter shall be considered as the heating value of the gas

delivered during such period. In the event a continuous gas

sampler is used, the heating value of the gas composite sample so

taken shall be considered as the heating value of the gas

delivered during the applicable period as determined by Gulf

South. In the event a spot sample is taken, the heating value of

the spot sample so taken shall be considered as the heating value

of the gas delivered during an applicable period as determined by

Gulf South.

 

All heating value determinations made with a chromatograph shall

use physical gas constants for gas compounds as outlined in the

1985 edition of A.G.A. Report No. 3 (ANSI/API 2530, GPA 8185) on

"Orifice Metering of Natural Gas" with any subsequent amendments

or revisions that meet generally accepted industry standards and

practices and are acceptable to Gulf South and Customer. Heating

value shall be determined to the nearest tenth of a Btu.

 

In the event the Btu value of the gas delivered at any delivery

point is not determined by any one of the methods described above,

the Btu content of the gas delivered during a month shall be

assumed to be the same as the weighted average of the Btu content

of the gas along the same pipeline segment determined by any of

the methods described above during such period.
