The fractionation and NGL storage complex in Mont Belvieu, TX, would surely qualify as one of the Seven Wonders of the Energy World, if there were such a list. With more than 250 million barrels of NGL storage carved — by water! — out of an enormous subterranean salt dome formation, and nearly two dozen fractionation plants with a combined capacity of more than 2 MMb/d, Mont Belvieu not only serves as the largest receipt point for mixed NGL streams on the planet, it is also the key hub of distribution for the ethane, propane, normal butane and other NGL purity products that are either consumed by Gulf Coast steam crackers and refineries or exported to foreign end-users. But unlike wonders of the ancient world like the Great Pyramids at Giza, Mont Belvieu is still very much a work in progress, with new storage caverns and new fractionators now under development to try to keep up with the breakneck pace of U.S. NGL production growth. Today, we begin a company-by-company review of fractionation capacity and other key infrastructure there.
