GTT’s Membrane Technologies Provide Solution For LNG-Fueled Ships

LNG shipping began in the 1960s with the launch of PYTHAGORE, a vessel featuring the integrated GTT Tank Mark I membrane. This initial GTT version was followed a few years later, when the METHANE POLAR (POLAR ALASKA, 1969) included the first form of the integrated GTT Tank NO-82 membrane.

New Technology at NASA Offers Full Control Of Cryogenic Liquids

As part of NASA’s plan for the first launch of its Space Launch System rocket and Orion spacecraft that will send humans beyond low-Earth orbit, Exploration Ground Systems at Kennedy Space Center is preparing to build the world’s largest liquid hydrogen storage tank incorporating the latest cryogenic liquid control technology...

US Increasing overall 2019 NASA Funding

The budget for NASA’s Science Mission Directorate is increasing by 11% in 2019, providing an additional $6.9 billion to current and upcoming projects. Missions to Jupiter’s moon Europa and a new lunar research initiative are among the beneficiaries, each analyzed by the American Institute of Physics.

Astronauts Assemble Tools to Test Space Tech

Technology helps push the development of future human missions to the moon, Mars and beyond. And in order for astronauts to journey farther and live longer, according to NASA, teams will need to store and transfer super-cold liquids used for fuel and life support systems in space.

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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...

Consultant knowledgeable in LNG

My company is seeking a consultant who is knowledgeable in LNG. It is a project located overseas, and involves a refinery and heat exchangers. Can anyone provide me with a reference?

Source for small gas liquefier/cryocooler?

I would like to acquire a used gas liquefier/cryocooler for use in my non-profit project to build a high-performance natural gas (methane) powered car. I am interested in liquefying piped natural gas (methane) into LNG (about 120K or -154 degrees).
