Syngas is often considered to be a petrochemical; although its production is a core industrial gases technology. Similarly, projects harnessing Landfill gas or biogas, Waste-to-energy schemes, as well as Hydrogen Production all exhibit overlapping technologies. Helium is an industrial gas, even though its source is from natural gas processing.
Several research organisations have released statements on the scarcity and conservation of helium. [6] [4] Among these are the American Physical Society, counting approximately 53,000 members, the Materials Research Society, an international organisation with 16,000 members, and the American Chemical Society, the world's largest scientific society with some 158,000 members.

Helium is a commonly used carrier gas for gas chromatography. The age of rocks and minerals that contain uranium and thorium can be estimated by measuring the level of helium with a process known as helium dating. [28] [30] Helium at low temperatures is used in cryogenics and in certain cryogenic applications.
Mahesh estimates that an MRI machine uses 10,000 liters of liquid helium over its life span. (According to GE Healthcare, a manufacturer of the machines, that life span is 12.8 years.) In 2015 ...
Map showing helium-rich gas fields and helium processing plants in the United States, 2012. From USGS. Helium production in the United States totaled 73 million cubic meters in 2014. The US was the world's largest helium producer, providing 40 percent of world supply. In addition, the US federal government sold 30 million cubic meters from storage.
Established in the 1920s for what was then a burgeoning blimp industry, the Federal Helium Reserve quickly became the go-to for scores of scientists and private companies when it came to sourcing ...
The design takes advantage of the inherent safety characteristics of a helium-cooled, graphite-moderated core with specific design optimizations. The graphite has large thermal inertia and the helium coolant is single phase, inert, and has no reactivity effects. The core is composed of graphite, has a high heat capacity and structural stability ...
Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...
