RECOVERY OPERATOR

Domain	Definition
Occupations	Controls evaporators, furnaces, and dissolving tanks to recover sodium compounds from chemicals spent in paper manufacturing processes: Patrols area around recovery units, observing recording devices and indicators on panelboards, flow of chemicals through units, and color of flame in furnaces to detect variations in pressure and temperature of evaporators, determine solid content of evaporated liquor, and detect incomplete burning of liquor in furnace. Turns rheostats to regulate pressure and temperature of evaporators, temperature and rate that liquor is sprayed into furnaces, and rate that molten sodium compounds are transferred from furnace to dissolving tanks. Tests solution at various stages of processing for specific gravity and titration, using testing devices. Adjusts and resets control instrument proportional bands on control board. Records meter readings at specified intervals on progress chart. (references)
	Operates rotary kiln, ball mill and conveying equipment to recover soluble soda and alumina from waste materials: Moves lever and switch controls to start and regulate rotation speed of kiln. Moves controls to maintain specified temperatures throughout kiln and feed rate of kiln. Catches samples of slurry clinker from kiln, and observes discharge of slurry at sample points to ensure specified burning. Moves controls of cooling air fan, cooler exhaust fan, and air dampers to adjust temperature of grate cooler and airflows to burners. Moves controls and adjusts feed valves to start conveyor and bucket elevator system and to transport calcined clinker, bauxite, and soda ash into ball mill. Regulates valves and pumps to transfer slurry from ball mill into digestion tanks and to supply water to kiln trunnions and water-cooled bearings. Keeps operating log. Replaces charts in automatic recording devices. (references)
	Controls distillation equipment to recover sulfuric and nitric acids from residue produced in manufacturing TNT and nitroglycerin: Turns valves and observes gauges and instruments to regulate flow of acids, steam, and water into denitrator tower to liberate nitric fumes, and to effect absorption of fumes in absorption towers for recovering acid of specified concentration. Draws acid samples for laboratory testing and pumps acid to storage tanks after laboratory approval. May determine concentration of acid, using hydrometer. (references)
