Mixes hydrosulfate solutions used in process, according to proportion chart or oral directions. Observes gauges to determine gas pressures throughout system, computes and records drops in pressure, and ascertains from data obtained optimum time to shut down and clean equipment for efficient operation. Draws samples of acids, brine, and gases from equipment units for laboratory analysis and determines specific gravity of brine, using hydrometer. Drains liquid from nitrogen driers.
Assists operator in maintaining operating log of gauge and instrument readings.
