· Cryogenic Processing. When martensite finish is below room temperature, we can use cold temperature treatments to transform more of the austenite to martensite. Here is the transformation of austenite to martensite vs temperature for T1 steel austenitized at 2350°F [6]:
· The VCone flow meter is often chosen for upstream, midstream, and downstream oil and gas appliions to measure a variety of flow media in various states and temperatures. The VCone's options for customization are among the many factors that prompt customers to choose this meter for cryogenic processes.
· Cryogenic gas processing plants cool natural gas until the heavier and more valuable NGLs form into liquids. These liquids – including propane, ethane and butanes can be used as fuels, fuel blending components and other valuable petrochemicals.

· Cryocompressed hydrogen storage technology is the most likely to achieve the hydrogen storage density goal proposed by DOE (see Table 1), which can significantly improve the hydrogen storage the same effective volume, the hydrogen storage capacity of cryocompressed hydrogen storage technology can reach 2–3 times of that of CGH 2, and times of that of liquid .
· Cryogenics simply takes the quench to new lows—minus 300°F. According to cryogenic treatment research done by Dr. Randall Barron from Louisiana State University, there are two primary mechanisms at work in the cryogenic treatment process.
· Cryogenic hardening is a process that uses cryogenic temperatures temperatures below −238 F. (−150 C.) to strengthen and enhance the grain structure of a metal. Without going through this process, the metal can be prone to strains and fatigue.
Cryogenic processing had its US origins in the 1940s. Cold treatments or sub zero treatments are done to make sure there is no retained austenite during quenching. Cryogenics is a relatively new process and to eliminate retained austenite, the temperature has to be lowered, but one that using correct procedures can bring substantial economic benefits.
CryoPress (Frozen Cell Crusher) is an equipment that freeze tissue which is difficult to be crushed and degenerates easily with liquid nitrogen and crush it. Analysis of biological substances such as protein, DNA, RNA extracted from tissues is necessary for research in various fields.
The cryogenic air separation plant production process is the most successful air separation process, practiced constantly in medium to large scale gas production plants. It is the most adopted technology for the generation of nitrogen (N2), oxygen (O2), and argon (AR) as gases and/ or liquid gases and thought to be the most costeffective technology for high production rate plants.
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.
· Cryogenic separation is a processing operation that is commonly used to extract natural gas liquids (NGLs) from raw natural gas. Unlike absorption methods, which are used primarily for extracting heavier NGLs, cryogenic processes are used to separate out lighter hydrocarbons such as ethane, propane, and butane from an incoming stream. ...
CRYOGENIC COOLING PROCESS Fig. 2 Cryogenic Cooling setup [8] The process of cooling the tool and workpiece during the metal cutting operation is known as cryogenic machining. In this process, liquid nitrogen and liquid CO₂ supplied through the storage tank to metal cutting zone instead of waterbased oilbased coolants.
· Take your pick. Both cryogenic and noncryogenic air separation processes have their advantages dependent on the specified volume and purity. Employing the right approach and the most appropriate cycles is critical if chemical engineers are to ensure air separation plants operate at maximum efficiency, and the highest levels of safety.
· Key to many cryogenic processes. Brazed Aluminum Heat Exchangers (BAHX) play an important role in cryogenics and are the most compact and energy efficient heat exchangers available for handling a wide range of services. They are particularly valued for their relatively high thermal efficiency, compactness, low weight and low maintenance.
· Fortunately, the flexibility of cryogenic freezing and chilling allows these technologies to provide solutions to many of the changing requirements. As new demands and needs are identified, cryogenics will continue to evolve to satisfy these needs and help the food industry move toward safer, more efficient processes. PCE Links
· The major process we will study is food freezing in its many forms, using ammonia, carbon dioxide or liquid nitrogen. When discussing cryogenics and food processing, we usually take a broad definition of the term "cryogenics," extending it to include carbon dioxide, which in its various forms is a very useful food cooling substance.
· This study investigated the effects of Deep Cryogenic Treatment (DCT) on machinability, hardness, and microstructure in dry turning process of AISI 4140 (4851 HRc) tempered steels with ceramic cutting tools on the surface roughness (Ra). DCT process of steels has shown significant improvement in their mechanical properties.
