MarkWest Building New Fractionation Plant in Harrison County, OH

Hopedale Fractionation Facility (click for larger version)
MarkWest Energy, now a subsidiary of Marathon Petroleum (MPLX unit) is THE premier shale gas processor in the Marcellus/Utica region. When natural gas comes out of the ground, a bunch of other hydrocarbons come out of the ground with it--namely NGLs (natural gas liquids). NGLs include compounds like ethane (C2H6), propane (C3H8), butane (C4H10), isobutane (also C4H10), and pentane (C5H12). MarkWest's cryogenic processing plants separate out the methane from NGLs. A different process, called fractionation, further separates the NGLs into their component parts. MarkWest handles an estimated 60% of all fractionation in the M-U. MarkWest has standalone plants set up to separate out ethane--called C2 fractionation because ethane has two carbon atoms. Ethane fractionation plants are their own separate beast--removing ethane from the NGL stream. Finally, there are C3 fractionation plants, which tackle separating the other NGLs--propane, butane, isobutane and pentane (referred to as C3+ fractionation because each of those compounds has three or more carbon atoms). In the Hopedale fractionation operation (Jewett, Ohio), MarkWest already has three C3+ fractionation plants up and running--Hopedale I, II, and III. Each one processes 60,000 barrels of NGLs a day, for a cumulative 180,000 bbl/d capacity. Honeywell issued a press release yesterday to say they have been tapped to build a fourth Hopedale C3+ fractionation plant, expanding MarkWest's capacity by another 60,000 bbl/d. Honeywell says it takes just 40 weeks from start to finish and they will have the Hopedale IV plant up and running, by the end of this year...
