1 Galonde GLP(70/30)es igual a 2.65 Mts3de Gas

NaturalA propsito de unarticulo publicado en Diario Libresobre el precio que tendr en el pas de manera inicial el Gas Natural y como dicho articulo no aclara correctamente lasequivalencias entre el Gas Natural y el GLP traigo a este blog el tema de l as equivalencias reales de este combustible.

De acuerdo a laAlternate nergy !ystemsel valor calor"ico del Gas Natural es #$%#& btu por pies c'bicos$ lo que equivale a ()$*(+.,* btu-m(.

eniendo en cuenta que el GLP es una me/cla de di"erentes gases$ siendo estos principalmente Propano y 0utano. !i tomamos como real la in"ormacin de 1ndustria y2omercio en el 3eglamento (%*4%#$ capitulo 511$ 2alidad de los 2ombustibles$ de la Ley de 6idrocarburos ##&4%%$que estipula que el GLP importado al pas debe tener unacomposicin de *%-(%$ que quiere decir mnimo *%7 de propano y m8imo (%7 de 0utano. 9btendremos los siguientes resultados:

Molar volume of a gasIt is equally as imortant to indicate the alica0le reference conditions of

temerature and ressure ,hen stating the molar volume of a gas *;1+as it is

,hen e/ressing a gas volume or volumetric flo, rate. "tating the molarvolume of a gas ,ithout indicating the reference conditions of temeratureand ressure has no meaning and it can cause confusion.

$he molar gas volumes can 0e calculated ,ith an accuracy that is usually

sufficient 0y using the universal gas la,for ideal gases. $he usuale/ression is=
