Analyzes specifications and controls continuous operation of
petroleum refining and processing units to produce products,
such as gasoline, kerosene, and fuel and lubricating oils, by
such methods as distillation, absorption, extraction,
adsorption, thermal and catalytic cracking and reforming,
polymerization, isomerization, coking, visbreaking, and
alkylation: Reads processing schedules, operating logs, test
results of oil samples, and laboratory recommendations to
determine changes in equipment controls required to produce
specified quantity and quality of product. Moves and sets
controls, such as knobs, valves, switches, levers, and index
arms, on control panels to control process variables, such as
flows, temperatures, pressures, vacuum, time, catalyst, and
chemicals, by automatic regulation and remote control of
processing units, such as heaters, furnaces, compressors,
exchangers, reactors, quenchers, stabilizers, fractionators,
rechargers, absorbers, strippers, debutanizers, stills, and
towers [Control-Panel Operator (petrol.
Refin.)].
Moves controls
to regulate valves, pumps, compressors, and auxiliary equipment
to direct flow of product. Reads temperature and pressure gauges
and flowmeters, records readings, and compiles operating
records. Determines malfunctioning units by observing control
instruments, such as meters and gauges, or by automatic warning
signals, such as lights and sounding of horns. Inspects
equipment to determine location and ntaure of malfunction, such
as leaks, breakages, and faulty valves.
Determines need for
schedules and performs repair and maintenance of equipment.
Patrols unit to verify safe and efficient operating conditions.
May sample liquids and gsaes [Sampler (petrol. Refin.)] and test
products for chemical characteristics and color [Tester (petrol.
refin.)]. May inspect and adjsut furnaces, heaters, and damper
controls. May lubricate equipment. May clean interior of
processing units by cicrulating chemicals and solvents through
them. May treat products [Treater (petrol. Refin.)]. May cotnrol
activities of several processing units operated in conjunction.
May be designated according to process involved or plant
operated as Absorption Plant Operator (petrol. Refin.);
Purification Operator (petrol. Refin.); Refinery Operator,
Cracikng Unit (petrol. Refin.); Refinery Operator,
Polymerization Plant (petrol. Refin.); Refinery Operator,
Reofrming Unit (petrol. Refin.); Refinery Operator, Vsibreaking
(petrol. Refin.). May be designated: Refinery Operator,
Alkylation (petrol. Refin.); Refinery Operator, Coking (petrol.
refin.); Refinery Operator, Crude Unit (petrol.
Refin.);
Refinery Operator, Gas Plant (petrol. Refin.); Refinery
