First Modern Liquid Oxygen Manufacturing Plant To Be Constructed At Tatu Industrial Park

Hewatele, a company based in Kenya that focuses on providing medical-grade oxygen and other healthcare solutions, held a groundbreaking ceremony for the construction of East Africa’s first modern liquid oxygen manufacturing plant, designed to address the rising demand for medical-grade liquid oxygen in healthcare facilities throughout the region. The advanced cryogenic medical...

Superconductor Offers Possible Room-Temperature Bridge

A new superconducting compound offers a bridge to more practical superconductors with a potentially attractive range of applications, according to new research. And the new material’s strange magnetic behavior recalls classic superconductors of decades ago—but this time in a material that’s already demonstrated its near-room-temperature bona fides. Lanthanum hydrides—which combine atoms of the...

How Low Can Temperature Go? Lord Kelvin and the Science of Absolute Zero

Temperature is probably the second most measured physical quantity in our modern world — after time. When I wake up in the morning, the first thing I usually check is the time (to see if I should go back to sleep), but the second thing I check is the temperature outside...

OPW Acquires Demaco in Cryogenics Consolidation

OPW announced today that it has completed the acquisition of Demaco, a provider of vacuum jacketed piping and other cryogenic equipment for gas producers, research institutions, EPC contractors, and end-users of liquefied gasses within various end-markets. Demaco will become part of the OPW Clean Energy Solutions business unit. Established in...

Into the Fast Lane for Quantum Innovation

The nascent quantum technology supply chain has reached an inflection point as companies large and small – among them household names like Google, Microsoft and IBM as well as a new wave of ambitious start-up ventures – shift gears to translate their applied research endeavours into at-scale commercial opportunities in...

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...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
