Chart Industries, Inc. has announced that its Distribution & Storage ("D&S") business in China has been awarded a contract to provide self-contained liquefied natural gas (LNG) station modules to Kunlun Energy Investment, a wholly owned subsidiary of PetroChina's Kunlun Energy.
Report on ICCR2013 in Hangzhou, China
Held at Zhejiang University, Hangzhou, China, April 6-9, the 5th International Conference on Cryogenics and Refrigeration (ICCR2013) attracted more than 330 participants from 17 nations and areas, with 220 papers presented.
Inside Fermilab’s New Strand and Cable R&D Lab
The mission of the Superconducting Strand and Cable R&D program is to understand and improve scientific and engineering aspects of superconducting strands and cables for accelerator magnets, including dipoles, quadrupoles and solenoids. Since 1998, the lab has also served as the ideal experimental environment for 30 graduate students in physics...
Cold Facts Tours NHMFL, ASC and CAPS
In February of this year, CSA was invited to the National High Magnetic Field Laboratory (CSA CSM) at Florida State University to tour its facilities and meet key personnel at the forefront of cryogenic and superconducting technology at the lab. On our tour we were taken behind the scenes to...
Does Cryogenic Electronics Have a Role in Electric Power?
Electric power systems—whether for electric utilities or on ships, airplanes or automobiles—require electronic power circuitry to change voltage levels and to convert between DC and AC, as well as for controlling power delivery. The use of superconductivity and cryogenics for motors, generators, energy storage and power distribution leads naturally to...

Joule-Thomson Effect
The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...
Current Leads
One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...
Multilayer Insulation
Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...
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...
Any experience with Tungsten or Tantalum metal springs in a low temp environment?
I would like to use metal springs made of Tungsten or Tantalum in low temperature environment. Does anybody have any experience with such springs? More precisely, I would like to make compression springs by rolling tungsten or tantalum wire on a rod. I expect that, typically, the spring constant will...
Standards & specifications for pipe & tube couplings
I am interested in finding out more about cryogenic applications and what standards, specifications and test methods (ASTM, etc.) are required for qualification of pipe and tube couplings.
Looking for a test house to test the static coefficient of friction under cryogenic conditions
I am looking to find a test house that is capable of testing the static coefficient of friction under cryogenic conditions. We can be flexible on most of the test parameters, including the test coupon configuration, but we’re looking for a test house that can provide the following test environment:...
Approximating pressure changes over time in cryogenic cylinders
I am an Air Resources Engineer with the California Air Resources Board (CARB). My senior management has asked me to investigate approximating pressure changes over time in cryogenic cylinders that contain LNG. So far, I have taken a stab at the problem, seeking to take a back-of-the-envelope approach (as directed...
