The properties of helium: Density, specific heats

the heat exchangers of a helium-cooled reactor require knowledge of some of the thermophysical properties of the helium gas, and the same applies to the treatment of observed data in heat transfer experiments. The properties treated in this report are the density, the specific heats, the thermal conductivity, and the viscosity. Get price

Helium recovery systems

When helium is withdrawn from an open cycle, e.g. for distribution to experiments or delivery to different users, it cannot be fed back into a liquefier without prior processing. Either the pressure or the liquefaction capacity is too small, the moisture content too high, or a combination of all of these. Get price

Process Technologies for Helium Recovery from Natural Gas

The nitrogen-rich feed is compressed to 2 bar and upgraded by cooling to 80.5 K in the first nitrogen removal stage, where part of the nitrogen is condensed to give a helium-enriched stream of 26 %. The gas is then warmed to ambient temperature, compressed to 31 bar and mixed with air to feed the hydrogen oxidation reactor. Get price

Measurement of Lung Volumes in Patients with Obstructive

Jul 19, 2013FRC can be measured using either nitrogen washout or body plethysmography. TLC is the sum of FRC and inspiratory capacity (IC), which is measured by spirometry. The accuracy of the nitrogen washout technique depends on all nitrogen (N 2) being "washed out" of the lungs. Get price
