Natural gas Some of these gases include heptane, pentane, propane and other hydrocarbons with molecular weights above methane (). The natural gas transmission lines extend to the natural gas processing plant or unit which removes the higher molecular weighted hydrocarbons to produce natural gas with energy content between . The processed natural gas may then be used for residential, commercial and industrial uses. Natural gas flowing in the distribution lines is called mid-stream natural gas and is often used to power engines which rotate compressors. These compressors are required in the transmission line to pressurize and re-pressurize the mid-stream natural gas as
Natural gas prices flows based on underlying index prices or delivery obligations or time periods. Participants use these tools to further hedge their financial exposure to the underlying price of natural gas. The demand for natural gas is mainly driven by the following factors: Weather conditions can significantly affect natural gas demand and supply. Cold temperatures in the winter increase the demand for space heating with natural gas in commercial and residential buildings. Natural gas demand usually peaks during the coldest months of the year (December–February) and is lowest during the "shoulder" months (May–June and September–October). During the warmest summer months (July–August), demand
