3. Physico-chemical properties
The characteristics of natural gas are well known and have been extensively described in various documents produced by GDF SUEZ. For example, please refer to .
Given the wide variations in composition, there are as many different specifications as there are natural gases. Compared with liquid fuels (gasoline and diesel), whose specifications are partly dedicated to combustion characteristics in internal combustion engines, natural gas specifications were originally developed for burner applications, and set logistically compatible impurity levels and energy content, but do not specify characteristics related to use as a vehicle fuel. The variations in composition...
