Tends catalytic reactor and auxiliary equipment that produce monovinylacetylene for use in neoprene rubber manufacture, as directed by MVA-REACTOR OPERATOR, HEAD: Determines specific gravity of brine solution in drier unit, using hydrometer, and turns valve to circulate brine through saturator to maintain strength at plant standard. Weighs prescribed quantities of materials, dumps materials into mixing tanks to prepare brine solution, and opens valve to admit brine to drier as directed. Moves controls to start equipment that removes byproduct solution from drier by continuous flotation. Draws samples of materials as directed and determines acidity, using standard chemical test equipment and procedure. Maintains acidity at specified level in equipment to prevent explosion hazard. Drains and flushes saturators, using steam hose, and refills units with calcium chloride to maintain saturator efficiency.
