METHOD FOR MIX-FILLING LIQUIDS HAVING DIFFERENT DENSITIES IN STORAGE TANK, AND METHOD FOR MIX-FILLING LIQUEFIED NITROGEN AND LIQUEFIED OXYGEN IN LIQUEFIED SUBSTANCE STORAGE TANK

摘要

PROBLEM TO BE SOLVED: To uniformly mix liquefied nitrogen and liquefied oxygen, which are liquids having different densities without increasing an oxygen gas concentration.;SOLUTION: By this method, respective liquids are filled in a storage tank in order to uniformly mix the liquids having different densities. First, one section of the liquid having a smaller density is filled in the storage tank. Then, in the liquid having the smaller density which has been filled in the storage tank, a specified amount of the liquid having a larger density is filled upward from the lower section of the storage tank. Then, both liquids are mixed in the storage tank. In the end, the remaining amount of the liquid having the smaller density is filled for the mix-filling method.;COPYRIGHT: (C)2002,JPO
