Performance of NBS Hydrogen Liquefier Plant
Because of urgent needs for liquid hydrogen and low temperature engineering information, this plant at Boulder, Colorado was rushed to completion, and the first hydrogen was liquefied on March 23, 1952. As laboratory facilities were completed and more low temperature engineering development projects were undertaken by NBS and others, the requirements for liquid hydrogen increased until it was necessary to produce as much as 12,000 liters in a month. The most produced in a single run was 5,300 liters.
