Scope and content
ca. 1952. Control room for production of anhydrous ammonia at the new ammonia plant, Hooker Electrochemical. Anhydrous ammonia is ammonia in the form of a gas. It is composed of three parts hydrogen to one of nitrogen. The hydrogen is obtained from electrolytic cells, which convert salt brine into caustic soda, chlorine and hydrogen. The rock salt used is obtained from the San Francisco bay area solar evaporation ponds. The nitrogen is obtained from the air by liquefying equipment manufactured by L'Aire Liquide of Montreal.
