Energy equipment solutions provider Dresser-Rand, part of Siemens Power and Gas, has commissioned its first micro-scale natural gas liquefaction system at the Ten Man liquefied natural gas (LNG) facility in the U.S. state of Pennsylvania. The modular, portable LNGo technology developed by the Dresser-Rand business enables distributed production of LNG and allows the operator, Frontier Natural Resources, to monetize stranded gas assets at Tenaska Resources LLC’s Mainesburg field, located in the Marcellus shale play.
The scope of supply included a standardized LNGo solution consisting of four different modules, each handling one step of the liquefaction process. The whole LNGo system can be transported on eight trucks. The Ten Man facility commenced production in mid-September last year, just four months from contract signing, and has produced approximately half a million litres of LNG since startup.
The LNGo technology makes it possible to monetize stranded gas deposits due to its relatively low capital and operating costs. The micro-scale LNGo solution can be deployed in rough terrain or remote regions, eliminating the need to establish an expensive gas pipeline infrastructure or arrange for long-distance trucking of LNG from centralized plants to point of use. It can function as a decentralized solution where the requisite pipeline infrastructure is lacking, or as an onsite transformation solution to reduce or eliminate flaring of petroleum gas at, for example, oil rigs or producing gas fields.
Capable of producing up to 30,000 gallons of LNG per day, the micro-scale LNG production plant can be tailored to meet national codes and standards with short cycle times.
Other than previously stated, upstream applications for the plant include on-site fuel supply for drilling and hydraulic fracturing equipment converted to run on LNG, and applications for coal bed methane for fueling mining vehicles. Downstream applications include the production of vehicle-grade LNG, allowing LNG to compete effectively with diesel fuel on a cost-per-energy-content (BTU) basis.
Frontier Natural Resources is an independent natural gas producer focused on developing conventional and unconventional resources.
