Cryogenic means lower heat values under -100 degrees. Cryogenic 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.
Perlite is used for storage of liquid gases (-270 C) to keep their temperature in needed values for storing them as liquid gases. Perlite is filled between double walls of vessels or tanks in atmosphere pressure and vacuum.
- Liqufied petroleum gas (LPG)
- Liqufied natural gases (LNG)
- Liquid nitrogen and ammoniac
- Liquid progane, ethane and methane
- Liquid oxygen
- Liquid noble gases, propellant gases (propellans), refrigerant gases (refrigerant etc.)
Perlite is used for prohibiting heat transfer to external environment(heat loss) for furnace with higher temperature working conditions. Free backfill is made outer surface of the furnace. (between double walls)
