February 2009 Chapter Event
Topic: Tour Rumpke Sanitary Landfill
When: Thursday Feb 26, 2pm
Montauk Energy Capital operates three methane gas recovery facilities at Rumpke Sanitary Landfill near Cincinnati. The plants convert the methane gas into natural gas energy. The first landfill gas recovery facility at Rumpke Sanitary Landfill opened in 1986, the second plant opened in 1995 and the third plant opened in 2007. The facilities have the potential to recover approximately 15 million standard cubic feet of landfill gas daily, making the recovery operation the largest landfill gas-to-direct-pipeline facility in the world. The plants combine to provide enough natural gas energy for about 25,000 homes and businesses.
The world's largest capacity LFG-to-high Btu gas processing facility is located at the Rumpke Landfill in Cincinnati, Ohio. It consists of three separate processing plants that are operated independently and in parallel. All three plants are owned and operated by Montauk's GSF Energy subsidiary. The first plant was constructed in 1986 and has an inlet capacity of 6 mmscfd. In 1995, the facility was expanded when a second plant was added to bring the total inlet capacity to 9 mmscfd. In June 2007, a third 6 mmscfd capacity plant was constructed, bringing the total inlet capacity at this site to 15 mmscfd.
All three of the Rumpke processing plants use pressure swing adsorption (a.k.a, molecular sieve) as the primary gas separation technology. This is a decades-old technology developed originally for use in the world's oil and gas fields. However, it first application on landfill gas was by GSF at Rumpke.
The pipeline quality gas produced at this facility is sold directly to Duke Energy for local distribution. Montauk's Rumpke project produces enough gas to serve the annual needs of 25,000 Cincinnati-area homes. It represents roughly 7 percent of the total annual volume consumed in the greater Cincinnati service area of Duke Energy. It is also the only local source of natural gas in the area.
