Vulcan: Tanking tests performed on ULA’s new rocket

Completing the next phase of testing in preparation for the inaugural Vulcan rocket flight, the United Launch Alliance (ULA) team accomplished tanking demonstrations at Cape Canaveral Space Force Station, Florida. The pathfinder tests filled the Vulcan first stage and Centaur V upper stage with cryogenic propellant on separate days to validate...

Next-Generation Oilless Cryogenic ORC Turbine Generator

Mitsubishi Heavy Industries, Ltd. (MHI) and Mitsubishi Heavy Industries Marine Machinery and Equipment Co., Ltd. (MHI-MME), a wholly owned operating company of MHI based in Nagasaki, have successfully conducted demonstration testing of 100 kW class cryogenic ORC (Organic Rankine Cycle) power generation using the world’s first “next-generation oilless cryogenic turbine...

Students Design Experimental Fuel System To Power Liquid-Propellant Rocket Engines

Aerospace Engineering students Alex Clay and Samir Ahmed have spent the past four years at Embry-Riddle Aeronautical University manufacturing complex liquid-propellant rocket engines. Now, as they near graduation, there is one last thing they’d like to do: Prepare for ignition. Along with fellow members of the university’s Experimental Rocket Propulsion Laboratory...

BCCK Boosts Propane Recovery with Next-Generation Technology at Cryogenic Gas Processing Facility

BCCK, a leader in engineering, procurement, fabrication and field construction services, has applied patent-pending technology, G2R-Flex®, to provide enhanced propane recovery for a premier midstream group in Ohio’s Marcellus-Utica Basin. Utilizing a skidded BCCK patent-pending design, G2R-Flex® improved current 200 MMSCFD GSP facilities’ propane recoveries to greater than 99 percent in...

GENH2 Partners with H2 Genesis to Provide Small-Scale Hydrogen Liquefaction

GenH2, an industry leader in hydrogen infrastructure solutions, announced that the company has signed a partnership agreement with H2 Genesis, a leading liquid hydrogen infrastructure and operations company, to deliver liquid hydrogen across North America. In their first collaboration, GenH2, as manufacturer, and H2 Genesis, as owner-operator, will deploy the...

First Measurements of Hydrogen-Boron Fusion in a Magnetically Confined Fusion Plasma

As fusion developers around the world race to commercialize fusion energy, TAE Technologies has pioneered the pursuit of the cleanest and most economical path to providing electricity with hydrogen-boron (also known as p-B11 or p11B), an abundant, environmentally sound fuel. Recently, the company announced, in collaboration with Japan’s National Institute...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
