ECO-07 - Calculation<br />
Online Gas Calorimeter<br />
Reported heating value specification for Russian natural gas IS 8116 Kcal/Kg. However, the<br />
techmcal SpecIalIsts complain that the delIvered heatIng value runs low by as much as 130<br />
Kcal/Kg (Avg. 42.1 Kcal/Kg) when the plant IS paYIng for gas on a volumetrIc basIs. They<br />
want to be able to measure the gas delIvenes on the basIs of heat content. An online gas<br />
calorimeter measuring and recordIng Kcal/Kg and Sp. Gr. costs about $35,000<br />

628,000,000 Nm 3 /Yr x 0.7207 Kg/Nm 3 = 452,590,600 Kg/Yr<br />
452,599,600 Kg/Yr x 42.1 Kcal/Kg = 1.905 x 10 10 Kcal/Yr<br />
1.905 x 10 10 Kcal/Yr x 3.9685 BTU/Kcal = 7 599 x 1010 BTU/Yr<br />

7.599 x 1010 BTU/Yr x $0.715/10 6 BTU = $51,407/Yr<br />
$35,000/$51,407 = 0.68 Yr = 8.2 months<br />

7,599 X 1011 BTU/Yr x $2.10/10 6 BTU = $158,739 Yr<br />
$35,000/$158,739 = 0.22 Yr = 2.6 months<br />
