In the March 24 article “Primus Planning Small-Scale GTL Facility Using Marcellus Gas,” NGI misstated the standard methanol capacity of a Primus plant (see Shale Daily, March 24). While the plants can be built in various sizes, a standard model already developed uses 5 MMcf/d of gas feedstock to produce 160 MT/d of methanol. NGI regrets the error.
