Performance criteria The tank shall be designed so that: Under normal operating conditions, the liquid and the vapour is contained; It can be filled and emptied at the specified rates; Boil-off is controlled and in exceptional cases can be relieved to flare or vent; Pressure operating range specified is maintained;
Cryogenic cooling is the only choice when you require fast tem-perature change (ramp) rates, or temperatures beyond the limits of mechanical refrigeration. While mechanical refrigeration is lim-ited to approximately –35°C (single stage) or –65°C (cascaded
Cryogenics is the study of material sciences at extremely low temperatures. Cryogenic temperatures are generally regarded to be below -180° Celsius. Cryogenics has many use cases in manufacturing and is often used in stress tests to evaluate the design of materials and products used in winter environments.

Cryogenic freezing is a type of freezing which requires extremely low temperatures, generally below -238 Fahrenheit (-150 Celsius). This process is part of a branch of the sciences known as cryogenics, which focuses on the production of very cold temperatures and the study of what happens to objects subjected to these temperatures.
The word cryogenics literally means "the production of icy cold"; however the term is used today as a synonym for low temperatures. The point on the temperature scale at which refrigeration in the ordinary sense of the term ends and cryogenics begins is not well defined.

13-04-2015· Cryogenic Technology Seminar Report with ppt and pdf. Cryonics, a derivative of nanotechnology is the speculative practice of using cold to conserve the life of person who can no higher be supported by general medicine. The first person to be cryogenically frozen was a 73-year-old psychologist, Dr. James Bedford; wh-o was suspended in 1967.
Cryogenic engineering is a branch of engineering that utilizes cryogenics for various domestic, commercial, scientific, medical and defense applications. Cryogenics is a branch of physics concerned with the production of very low temperatures and the effects of these temperatures on different substances and materials.
Research activities of our laboratory can be broadly classified into two categories: heat transfer and solid sorption storage/ cooling. Heat transfer research aims at miniaturisation of heat exchangers.Miniaturised, cryo-compatible heat exchangers offer challenges to achieve high efficiency with reduced heat ingress, axial heat conduction, pressure drop and preferably at low cost.
