Equipment cooled storage

The principle of cool storage was used many years ago when motion picture theaters introduced air-conditioning to the general public. Precooling of the theater prior to opening and during off-peak load hours saved on electricity costs and also cut down on the investment in air-condihomng equipment. 

Conditions for safe storage, including incompatibilities Storage containers must be grounded and bonded. Store away from all ignition sources in a cool area equipped with an automatic sprinkling system. Ensure adequate ventilation. Store at temperatures between - -5°C and -f 50°C. Store only in the original container.

LIQUID CONSUMPTION, When used to maintain temperatures at 20 K, for each tensile experiment the cryostat uses about 2 liters of liquid nitrogen for pre-cooling the equipment and about 2 liters of liquid hydrogen of which 1.8 liters is accounted for by the capacity of the cryostat and the remainder is vaporized in transfer from the storage dewar andin cooling the cryostat to 20°K. 

Mercury vapor discharge from vents of reactors or storage tanks at normal atmospheric pressure is controlled readily by means of activated carbon. Standard units (208-L (55-gal) dmms) of activated carbon equipped with proper inlet and outlet nozzles can be attached to each vent. To minimize the load on the carbon-absorbing device, a small water-cooled condenser is placed between the vent and the absorber. 

This stock is discharged from the mixer to equipment that allows cooling and a convenient storage form, such as a mill or an extmder/die plate that yields a sheet or pelletized form. Usually the material is coated with a slurry of clay, calcium carbonate, or zinc stearate to prevent self-adhesion.
