To the layman, Enterprise Products’ Mont Belvieu petrochemical complex just east of Houston speaks to an industrial process most find shrouded in mystery where steam puffs 24/7 amid lights that illuminate the wide Texas nightscape. But for those in the oil and gas industry, Enterprise’s Mont Belvieu complex is a steel-and-pipe engineering marvel that converts NGLs into the raw materials used to manufacture just about everything the layman uses.

Enterprise Products

Enterprise Products Partners L.P. is an American midstream natural gas and crude oil pipeline company with headquarters in Houston, Texas. It acquired GulfTerra in September 2004. The company ranked No. 105 in the 2018 Fortune 500 list of the largest United States corporations by total revenue.

Since its initial construction, the Enterprise complex has experienced a near non-stop expansion, adding more fractionators and capacity to meet growing global demand for the basic building blocks of commercial goods. And news from Enterprise’s Mont Belvieu facility also is ongoing with the company’s latest announcement of a long-term agreement with Marubeni Corporation to supply polymer grade propylene (PGP) from a second propane dehydrogenation plant (PDH2) still under construction.

Japan-based Marubeni is an integrated trading and investment conglomerate, as well as the world’s largest olefins trader. Olefins are the basis for polymers and oligomers used in plastics, resins, fibers, elastomers, lubricants, gels, solvents, detergents and adhesives.

Upon completion in 2023, PDH2, combined with six other Enterprise propylene fractionators, will have a total capacity to produce up to 11 billion pounds per year of polymer grade propylene. The company’s PGP assets include more than 300 miles of delivery pipelines, 26 connections, more than 5 MMBbls of storage, and a new export terminal that opened for business earlier this year.

To keep our subscribers up to date, here’s a look at the Enterprise NGLs wonderment so far in the last now seven months.

In RMR’s story The Enterprise That Grows Behind NGL Exports published earlier this year, we told you about the company’s inaugural ethylene cargo leaving from Enterprise’s new NGL export terminal along the Houston Ship Channel. Upon completion this year, the company’s ethylene facility at the Mont Belvieu complex will have enough capacity to produce 1 million mt/year. Enterprise at the time also announced plans to bring online two more fractionators to make propylene and isobutylene, as well as increase its ship-loading capacities of propane and butane from 32,000 barrels per hour to 40,000.

We then covered the start-up of Enterprise’s new isobutylene dehydrogenation (IBDH) plant at Mont Belvieu in our story Enterprise Advances U.S. NGL Exports. Once in full gallop, the IBDH will be capable of processing 25,000 BPD of butane into nearly 1 billion pounds of isobutylene a year. China and India are the largest importers. Enterprise’s isomerization complex is the largest of its kind in the nation and includes a 70-mile pipeline system to transport high-purity isobutane from Mont Belvieu to Port Neches, Texas.

As recently as June, we shared Enterprise, Navigator Set to Export Record Ethylene Tonnage, which they did, shipping 44 million pounds of ethylene to Japan.
