PART 1 – REFINERY FUNDAMENTALS (Facts 1–50)
1.

A shutdown or turnaround is one of the few times major equipment can be inspected and repaired.
5.
Crude oil is a mixture of hundreds of different hydrocarbons.
6.
The first process in most refineries is atmospheric distillation.
7.
Products are separated by boiling point.

23.
Nitrogen is commonly used for purging systems.
24.
Hydrogen plays a major role in producing cleaner fuels.
25.
Sulfur is removed from fuels to reduce emissions.
26.
Some refineries process light crude.
27.
Others are designed for heavy crude.
28.
The complexity of a refinery influences its profitability.
29.
Some facilities can process multiple crude blends simultaneously.
30.
Refineries continuously recycle process streams.
31.
Heat integration improves energy efficiency.
32.
Flare systems safely burn excess hydrocarbons.
33.
A flare should not automatically be viewed as an emergency.
34.
Operators regularly conduct equipment inspections.
35.
Preventive maintenance reduces failures.
36.
Predictive maintenance detects problems before breakdowns occur.
37.
Corrosion is one of the industry’s biggest challenges.
38.
Inspection programs monitor wall thickness.
39.
Ultrasonic testing is widely used.
40.
Radiography helps inspect critical welds.
41.
Pressure vessels must meet strict engineering standards.
42.
Every pipe has a pressure rating.
43.
Every flange has a pressure class.
44.
Valve selection depends on service conditions.
45.
Material selection depends on temperature, pressure, and corrosion.
46.
Safety always takes priority over production.
47.
Most refineries require extensive worker orientation before entering the plant.
48.
Every worker should know emergency evacuation routes.
49.
Communication between crafts prevents costly mistakes.
50.
The best journeymen understand how the entire refinery works—not just their own trade.
PART 2 – REFINERY EQUIPMENT (Facts 51–100)
51.
Pumps move liquids through the refinery.
52.
Compressors move and compress gases.
53.
Heat exchangers transfer heat between fluids.
54.
Distillation towers separate hydrocarbons.
55.
Pressure vessels safely contain pressurized fluids.
56.
Boilers generate steam.
57.
Cooling towers remove excess process heat.
58.
Storage tanks hold raw materials and finished products.
59.
Large storage tanks can hold millions of gallons.
60.
Tank farms often occupy hundreds of acres.
61.
Shell-and-tube heat exchangers are among the most common designs.
62.
Heat exchanger fouling reduces efficiency.
63.
Cleaning heat exchangers is a common turnaround task.
64.
Centrifugal pumps are widely used.
65.
Positive displacement pumps are used where constant flow is required.
66.
Mechanical seals help prevent leaks.
67.
Seal failures are a common maintenance issue.
68.
Bearings require proper lubrication.
69.
Pump alignment directly affects reliability.
70.
Laser alignment improves equipment life.
71.
Compressors can be reciprocating, centrifugal, or screw type.
72.
Steam turbines often drive large pumps.
73.
Electric motors power much of the refinery.
74.
Gearboxes increase or reduce equipment speed.
75.
Expansion joints absorb thermal movement.
76.
Pipe supports carry tremendous loads.
77.
Spring hangers compensate for pipe expansion.
78.
Anchor points control thermal movement.
79.
Valve actuators may be pneumatic, hydraulic, or electric.
80.
Gate valves are primarily used for isolation.
81.
Globe valves are commonly used for throttling.
82.
Ball valves provide quick shutoff.
83.
Butterfly valves are common in large-diameter piping.
84.
Check valves prevent reverse flow.
85.
Safety relief valves protect equipment from overpressure.
86.
Every pressure vessel has a design pressure.
87.
Pressure gauges require periodic calibration.
88.
Temperature instruments also require calibration.
89.
Flow meters measure fluid movement.
90.
Level transmitters monitor tank and vessel contents.
91.
