In a power plant, the primary use of vacuum systems is to remove air and other noncondensable gases from the shell side of the condenser in order to maintain design heat transfer and thus design ...

Atmospheric air will enter a refrigeration system any time it is opened for service or any time a new system is being assembled. Atmospheric air contains nitrogen, oxygen, and water vapor, all of ...

If a vacuum line much smaller than the flange diameter of the turbopump (DN 100 (100 mm)) is used, the effective pumping speed will decrease. A DN 25 (25 mm) vacuum line will result in only around 7.4 ...

A complex piece of equipment, the converging-diverging steam jet used in vacuum distillation units is subject to a wide array of malfunctions that are often misunderstood or overlooked by plant ...

Advanced vacuum technologies are redefining safety, efficiency, and purity across every stage of lithium-ion battery ...

Cool idea: NIST’s Daniel Barker, Steve Eckel, Jim Fedchak, Julia Scherschligt and colleagues have developed and tested a technique that uses cold atoms to measure ultralow pressures. (Courtesy: NIST) ...

Using dry nitrogen to pressure test a system is a very effective method of verifying a system is leak-free. In fact, I believe it is more reliable than using a standing vacuum test typically performed ...
