Chart Industries wins $45m+ LNG equipment contract

Chart Industries, Inc., an independent global manufacturer of highly engineered equipment used in the production, distribution, storage and end-use of hydrocarbon and industrial gases, has announced that its Distribution & Storage (D&S) business in China has been awarded a new contract to provide liquefied natural gas (LNG) fueling stations, self-contained...

US House passes bill to head off massive helium shortage

On April 26, the US House of Representatives passed a bill by a vote of 394 to 1 that would head off a critical shortage of helium that is sure to strike in October if Congress does nothing. That news should come as a relief to the thousands of scientists...

Herschel closes its eyes on the universe

ESA’s Herschel space observatory has exhausted its supply of liquid helium coolant, ending more than three years of pioneering observations of the cool Universe.

Two new senior staff scientists appointed at SLAC

The leader of SLAC's involvement in the Cryogenic Dark Matter Search and an instrument scientist with the Linac Coherent Light Source X-ray laser have been appointed senior staff scientists at SLAC.

CGA announces the 5th edition of the Handbook of Compressed Gases

The fifth edition of the CGA's Handbook of Compressed Gases has been significantly revised with expanded content, updated regulatory and technical information, and color graphs and figures to meet the needs of today's compressed gas industry.

Cryogenic Dark Matter Search adds new intrigue with the latest result

Physicists operating an experiment located half a mile underground in Minnesota reported that they have found possible hints of dark-matter particles. The Cryogenic Dark Matter Search experiment has detected three events with the characteristics expected of dark matter particles, MIT graduate student Kevin McCarthy reported at the American Physical Society...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
