microspheres, referred to as bubbles, and perlite insulation for liquid hydrogen tank applications. Two identical 1/15 th scale versions of the 3,200,000 liter spherical liquid hydrogen tanks at
Complete range of tank sizes from 1500* to 264,000 US gallons (6,000 to 1,000,000 liters) at maximum allowable working pressures between 175 and 500 psig (12 Cryogenic Perlite - GenperCryogenic tanks are produced for usage in storing and transferring gases in liquid phase at -100 degrees. Isolation is important for keeping gases in liquid phase.In lower temperature (-270 C) perlite is used for storing all gases in double walled vessels. Perlite is filled between double walls of vessels or tanks in atmosphere pressure and vacuum. HEAT ISOLATION OF CRYOGENIC TANKS
Perlite is made of perlite ore, a mineral that is a natural resource with an almost endless supply. Its known for its foam-like internal structure, which makes it a low-density insulator; perfect for liquid nitrogen, oxygen, and cryogenic storage tanks and LNG pressure vessels. Go LNG Tank Construction Using Insulating Perlite Concrete Perlite concrete blocks have been used to insulate the base of double wall cryogenic tanks to insulate between the ground and the bottom of the tank itself. These blocks are being used because of their good load bearing strength, excellent thermal properties and resistance to seismic forces.
It is because of these unique properties that Perlite has found wide acceptance in the insulation of cryogenic and low temperature storage tanks, cold boxes, shipping containers and food processing facilities. In addition to its thermal properties, Perlite is relatively low in cost, easy to Research and Development History of Glass Bubbles Bulk development of glass bubbles bulk-fill thermal insulation systems for cryogenic equipment in general and, in particular, for large-scale cryogenic liquid hydrogen (LH2) storage spheres. Glass bubbles (also known as hollow glass microspheres) are used in place of perlite

The liquid hydrogen and oxygen cryogenic storage tanks at John F. Kennedy Space Center (KSC) use expanded perlite as thermal insulation. Some of the perlite may have compacted over time, compromising the thermal performance and also the structural integrity of the tanks.
