An Air Liquide low-temperature separation installation at Petroleum Chemicals Inc., Lake Charles, La., U.S.A. Products of the installation include oxygen and nitrogen in tonnage quantities and ammonia synthesis gas.
RECOVER HYDROGEN ECONOMICALLY with your own low-temperature separation unit The tremendous increase in the use of pure hydrogen by the ammonia industry — t h e largest market — and its increasing importance in space rocketry and missiles, have led to a need for even larger supplies. To tap the available rich sources, Air Liquide's low-temperature gas separation process offers many advantages in stripping hydrogen from refinery streams, coke-oven gas, and reformed natural gas, at low cost. This low-temperature process makes available the recovery of such valuable hydrocarbons as methane, ethylene, benzene, and liquefied petroleum gas fractions. Furthermore, it is the only hydrogen recovery process that preserves the thermal and chemical values of these hydrocarbons. Our company's first low-temperature hydrocarbon separation plant went into operation in 1920. Since then, we have designed and built plants throughout the world. Air Liquide units lend themselves to remote operation with minimum supervision. With American Air Liquide you recover hydrogen at lower cost. Today, Air Liquide cryotechniques make possible the safe production, storage and delivery of hydrogen in tonnage quantities to any location. If your problem is hydrogen recovery, purification o r liquefaction, we can design and build units in a wide range of capacities from 25 tons to as high as 350 tons per day. ALL AIR LIQUIDE LOW-TEMPERATURE PLANTS ARE DESIGNED A N D BUILT IN NORTH AMERICA FROM AMERICAN MATERIALS A N D TO NORTH AMERICAN STANDARDS.
