Magnolia LNG awards $40 million for liquefaction equipment

Magnolia LNG, a subsidiary company of Liquefied Natural Gas Limited, announced on September 22 that it had awarded $40 million in contracts to Chart Industries, Inc., for a mid-scale LNG project at Lake Charles LA. Chart will initially deliver two identical trains, each with a nominal LNG production capacity of...

DOE posts new Women@Energy profiles

The Department of Energy recently updated its Women@Energy webpage to include new profiles on researchers working at its national laboratories. There are now over 250 profiles on the page, each celebrating a woman who works in a STEM field. The new profiles include female scientists working at Jefferson Lab (CSM)...

New test using cryogenic sapphire oscillators confirms speed of light

Researchers from the University of Western Australia and Humboldt University of Berlin used cryogenic temperatures to optimize frequency stability in a test designed to measure the spatial consistency of the speed of light with a precision ten times greater than ever before. The experiment compared the extremely pure microwave frequency...

Young Faces: The Next Generation in Cryogenics

We're pleased to present a new installment of Young Faces, a feature story we debuted in the Summer 2006 issue of Cold Facts introducing outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in...

CSA Awards Presented at CEC/ICMC

John Weisend, CSA chairman, presented four awards at CEC/ICMC on July 1, including the first-ever William E. Gifford Award, given to a recipient in academia or at a government laboratory using a pulse tube or Gifford-McMahon cycle cryocooler as a key research component.

The 26th Space Cryogenics Workshop

This column presents a topical summary of the 2015 Space Cryogenics Workshop that was held June 24-26 in Phoenix AZ. The workshop was organized by David Plachta and Jason Hartwig of NASA/Glenn Research Center, and continued the tradition of bringing together specialists in the field of space cryogenics to discuss...

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

Air Separation and Liquefaction

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

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...
