TITLE(s): SATURATOR OPERATOR (chemical; steel & rel.) alternate titles: ammonium-sulfate operator;
sulfate operator
Controls saturator tank and auxiliary equipment to precipitate ammonium sulfate by reaction of
ammonia with sulfuric acid: Turns valves to admit sulfuric acid and liquid or gaseous ammonia to
saturator until precipitation occurs, and to regulate saturation of solution, using titration test
to determine acidity of bath. Observes temperature and pressure gauges to ascertain that process
conditions meet plant standards, and turns valves to maintain operating equilibrium within specified
range. Notifies supervisor or starts pumps to discharge precipitate onto drain table to settle out
crystals, and pumps strained liquor back to bath. Records gauge readings for operating log. May move
controls to reheat gas prior to saturation. May tend centrifuge to dry ammonium sulfate. May take
samples of product and constituents for laboratory analysis.
