As many companies and producers of energy are looking toward establishing a cleaner future, a great amount of consideration is being put into the environmental impact of various fuels. As oil and gas will continue to be used in many industries for the foreseeable future, liquid natural gas (LNG), has become used more frequently, especially in various aerospace applications. Valve World Americas had the opportunity to speak with valve expert Scott Moreland to gain more insight on the future of the valve market, and which valves are best suited for these applications.

The Fife LNG plant at Mossmorran, operated by Shell, can provide a challenging environment for any high-pressure valve, but when a need arose for a number of ANSI class 300 DBB valves with a high operating temperature range, few manufacturers could meet the requirements.

Badak LNG is one of the largest natural gas liquefaction plants in the world, located in Bontang, Indonesia. There are 8 process trains - capable of producing 22.5 Million Metric Tons Per Annum of LNG - and they use steam turbines for driving power generation and refrigeration compressors. On January 27, 2011, a routine inspection detected several cracks on a 24” #600 gate valve located on a steam line.

It might be difficult to believe, but there used to be a joke about a geologist reporting back over a field trip and saying: ‘I have good and bad news; the bad news is that we did not find any oil; the good news is that we did not find any gas either.’

As most piping specialists know, LNG applications can be very difficult to control flow, and it takes a special design with specific materials to work in temperatures ranging down to -454˚F/-270˚C. A design and materials which cannot be utilized in most valve types. While both gate valve and ball valve designs have been utilized, they do not always provide the very best of results – zero leakage in on/off applications.

Liquefied natural gas (LNG) is natural gas in a liquid form that is clear, colorless, odorless, non-corrosive and non-toxic.

Quality and safety are the two critical considerations when choosing a valve. Cryogenic valves are the solution.Cryogenic valves and other media are susceptible to extreme temperatures.

Woodfibre LNG, a Canadian subsidiary of Singapore’s Pacific Oil & Gas Ltd., is finalizing the engineering, procurement and construction contract for their $1.6 billion LNG export facility in Squamish, British Columbia.

U.S. exports of liquefied natural gas (LNG) have been growing steadily and reached a new peak of 4.7 billion cubic feet per day (cf/d), according to the latest data published by the U.S.
