Liquid Air Energy Storage: How Cryogenics Can Support a Greener Grid

The LAES system charges using an industrial air liquefier based on the Claude cycle used on the front end of existing air separation units. Electricity from the grid is used to produce liquid air at close to ambient pressure, thus avoiding the excessive cost of containing a high-pressure fluid in...

VNR Advances New Process to Ensure Reliability of Space-Flight-Critical Fasteners

In October 1989, while investigating the crash landing of United Flight 232 in Sioux City, the NTSB located the fan disk from the plane’s number two engine in a cornfield near Alta, Iowa. It was in two pieces, ripped apart, the agency later determined, when an undetected metallurgical defect resulted...

Chart Acquires VCT Vogel

On September 1, Chart Industries, Inc. (CSA CSM) announced its acquisition of VCT Vogel GmbH, a German firm servicing cryogenic and other mobile gas tank equipment and trucks. Founded in 2001, VCT has established itself as a provider of truck-mounted drive and control systems for the operation of cryogenic pumps...

New Director General at ESO

Xavier Barcons became the eighth director general of the European Southern Observatory on September 1, succeeding Tim de Zeeuw who had served since 2007. Barcons begins his tenure at an exciting time for ESO, as construction of its Extremely Large Telescope is progressing and it is set to see first...

New Report Buffers Possibility for Molecular Level Data Storage

New research from the University of Manchester (UK) suggests that storing data with a class of molecules known as single-molecule magnets is more feasible than previously thought. The result, published in Nature, shows that magnetic hysteresis, a memory effect that is a prerequisite of any data storage, is possible in...

Brooks Automation Expands Stored Sample Monitoring

Brooks Automation, Inc. (CSA CSM) has acquired FreezerPro® and other assets from RURO, Inc., a Maryland-based developer of computer software for research, biotechnological, pharmaceutical, healthcare and government laboratories. The software enables web-based access to information on stored samples from any location on any device.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Air Separation and Liquefaction

by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. 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...

TS diagram for helium

Where can I obtain a really big, nice TS diagram for helium ?

Reliability and mounting of electronic substrates at low temperatures

I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...

Are 3D drawings included in the sale of a cryogenic plant?

I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...

Looking for a source of LOX impact testing to ASTM D2512

I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
