FUNDAMENTALS OF NATURAL GAS CHEMISTRY

Natural Gas Natural gas is a mixture of many compounds which can be classified into three major groups--hydrocarbons, inerts, and miscellaneous trace compounds. Hydrocarbons are compounds which contain hydrogen and carbon. Most of the hydrocarbons in natural gas are saturated, meaning that each carbon atom is bonded to four other atoms while each
