Air Products LNG Peak Shaving Plant Experience The early success of Air Products' LNG peak shaving plant design did much to bolster confidence in the safe handling of LNG and to promote acceptance for LNG peak shaving in the United States. The plants listed below incorporate a variety of processes that demonstrate the skills, flexibility, and experience of Air Products' personnel. The Company has had operating responsibility and ownership participation in several of the following plants.
Alagasco
In 1965 Air Products began operation of the LNG peak shaving plant for Alabama Gas Company in Birmingham. This plant makes use of the Air Products cascade refrigeration system design with a gross liquefaction capacity of 4.65 MMSCFD, storage for 1,200 MMSCF, and vaporization capacity for 125 MMSCFD.
Boston Gas Company
The first domestic application of the Air Products' MCR® Process was the 7.85 MMSCFD liquefaction capacity peak shaving facility located at Lynn, Massachusetts. This plant is currently owned by Boston Gas Company. Air Products designed, constructed, and handled initial operation of this plant.
British Gas Council
This plant is a peak shaving and reliquefaction plant designed by Air Products and located on Canvey Island, England. It uses the MCR® Process and has a liquefaction capacity of 10.76 MMSCFD.
Cove Point
In 1994 Air Products was selected by Columbia Gas to provide the process design and major equipment for a 15 MMSCFD peak shaving plant located at the Cove Point, Maryland LNG import terminal. The plant uses the MCR® Process and began operation in 1995.
Hopkinton LNG Corporation
Air Products operates and maintains the 18.5 MMSCFD cascade refrigeration peak shaving plant located at Hopkinton, Massachusetts. This plant is owned by Commonwealth Gas.
Air Products was also responsible for the process design, equipment supply, and construction of a satellite plant capable of storing the liquid equivalent of 500 MMSCF of natural gas with a vaporizing capacity of 30 MMSCFD. This plant is located in Acushnet, Massachusetts and is owned by Commonwealth Gas.
JAPEX I
Air Products provided the process design and cryogenic equipment for a new grass roots, 150 ton per day natural gas liquefaction and storage facility for JAPEX located in Yufutsu, Japan. The plant uses Air Products nitrogen recycle liquefaction technology and was commissioned in March 2004.
JAPEX II
Air Products was subsequently selected to provide the process design and cryogenic equipment for a 200 ton per day second train expansion at JAPEX’s Yufutsu site. This plant uses Air Products nitrogen recycle liquefaction technology and was commissioned in September 2007.
National Grid (originally Keyspan Energy)
Air Products provided the process design and major equipment for a replacement 6.3 MMSCFD liquefier at National Grid’s Holtsville, NY peakshaving facility. This plant was the first liquefier to use Air Products proprietary nitrogen recycle liquefaction technology and included a nitrogen expander/compressor designed and manufactured by Air Products. The plant was commissioned in September 2001.
Philadelphia Gas Works (PGW)
Air Products provided the process design and major equipment for a replacement 18 MMSCFD liquefier at PGW’s Port Richmond, Philadelphia, PA peakshaving facility. This plant uses natural gas expansion for the refrigeration cycle and contains two Air Products designed and manufactured natural gas expander/compressor sets. The plant was commissioned in March 2005.
