Three hours west of Washington, D.C., U.S. Route 50 emerges from the West Virginia forest in a gentle curve. On the south side of the highway rises an enormous natural gas drilling rig. To its left and slightly behind it is a gas separation plant under construction. This is the “wet gas” portion of the Marcellus shale-gas play that underlies Appalachia. The separation plant will divide the wet gas into propane, pentane, butane and the like. In front of the rig and closest to the highway is a kind of filling station with color-coded fittings instead of hoses on the pumps. When it’s completed, 40 tanker trucks a day will pull up and load the various gases for delivery to plants up the chemistry food chain.
