ECONOMIC USE OF LIQUID NITROGEN AND LIQUID HELIUM. A LARGELY OVERLOOKED ASPECT OF ENERGY SAVING.

Author(s) : KLIPPING G., KLIPPING I.

Summary

THE ARTICLE REFERS TO THE POSITION IN GERMANY WHERE THE USE OF LIQUID NITROGEN AND LIQUID HELIUM HAVE RISEN CONSIDERABLY IN RECENT YEARS. IT IS MORE ECONOMIC TO PRODUCE THESE LIQUIDS AT CENTRES RATHER THAN INDIVIDUAL PRODUCTION AT RESEARCH INSTITUTIONS AND OTHER USERS. TRANSPORT TO LOCALISED STORAGE FACILITIES AND FROM THERE IN STANDARD 100 L DEWARS IS NOW THE USUAL METHOD OF SUPPLY. STANDARD DEWARS OF LIGHT-WEIGHT ALUMINIUM AND PLASTIC, SUPERINSULATED, HAVE BEEN RECENTLY DEVELOPED. THE MAJOR PROBLEMS WHICH ARE STILL TO BE OVERCOME ARE THE LOSSES OCCURRING IN TRANSFER TO STORAGE AND TO THE USER DEWARS. ESCAPING GAS, BEING UNDETECTABLE, GOES UNNOTICED. AT BEST ONLY 40% OF STORED LIQUID HELIUM IS USUALLY AVAILABLE FOR COOLING. D.W.H.
