Altus Midstream Announces First Cryogenic Processing Train in Service at Texas Complex
Altus Midstream introduced the first of its three new cryogenic processing trains at the Diamond Cryo Complex in Alpine High TX. It is now processing rich natural gas and delivering natural gas liquids (NGLs) and residue gas for sale.
Department of Energy Announces $75 Million for High-Energy Physics Research
The US Department of Energy recently announced grants of $75 million in funding for 66 university research awards. The projects involve scientists at 51 US institutions of higher learning and include both experimental and theoretical research into topics like the Higgs boson, neutrinos, dark matter, dark energy and the search...
Blue Origin Test-Fires Moon Lander Engines
Blue Origin recently fired up a brand-new engine, the BE-7, which the company developed for its future moon lander. Founder and CEO Jeff Bezos claims the lander, equipped with the BE-7, will be capable of carrying robotic rovers to the moon or even a separate spacecraft that can take off...
Air Liquide Signs Two Long-Term Oxygen Supply Agreements with Marathon Petroleum Corporation
Air Liquide advanced Technologies (CSA CSM) has signed two long-term supply agreements with Marathon Petroleum Company for a total of up to 900 tons of oxygen per day for Marathon Petroleum’s Refineries on the American Gulf Coast.
Shaw Prize in Astronomy Awarded to Edward Stone
Former Jet Propulsion Laboratory director Edward Stone has been awarded the prestigious Shaw Prize in Astronomy for his leadership in the Voyager project. The Shaw Prize is awarded annually in three categories: Astronomy, Life Science and Medicine, and Mathematical Sciences, and comes with a monetary prize of $1.2 million. Stone...

Transfer Lines
Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...
Zero Boiloff
Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...
Cryomodule
Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...
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...
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...
