Note From Desk of Duane Nichols, Chemical Engineer.

The above Article by Susan Phillips contains the following phrase: “………during five years of construction on the liquified natural gas pipeline system.”

Technically speaking, this Mariner East pipeline system transports “natural gas liquids” i.e. NGL and not LNG. Here is the difference, NGL is ethane, propane, and butane, that are known as the higher (larger molecules) hydrocarbons from natural gas production. LNG is almost exclusively methane.

The frack gas from the so called “wet zone” in northern WV, western PA and eastern OH contains substantially more NGL than does conventional raw natural gas, the latter being over 90 % methane (CH4).

There are no cases where natural gas is transported over such distances as a liquid (LNG). The temperature required is too low to be maintained over such a time and distance, in this case essentially the entire distance across Pennsylvania.
