The primary difference between a kettle reboiler and other heat exchangers is:

A vapor disengaging cavity

The basic components of an electrical motor include all of the following:

Bearings and seals, stator windings, rotor and shaft, and frame and fan.

The basic furnace designs include:

Cabin, box, and cylindrical

What is the primary purpose of the hot work permit?

To protect plant personnel from fires and explosions and to comply with PSM.

A system is best described as a:

Collection of equipment designed to perform a specific function.

The primary purpose of a cooling tower is to:

Cool water

The Resource Conservation and Recovery Act (RCRA) was enacted as Public Law in 1976. The purpose of the RCRA is to protect human health and the environment. A secondary goal is to conserve our natural resources. RCRA completes this goal by regulating all aspects of hazardous waste management; generation, storage, treatment, and disposal. This concept is referred to as __________.

Cradle to grave

List two processes furnaces support:

Distillation and reactor processes

In an industrial environment responding to an emergency follows a specific set of standards. __________ drills are carefully planned and include preparations for worst case scenarios. Examples are: vapor releases, chemical spills, explosions, fires, equipment failure, hurricane, high winds, loss of power, bomb threats, etc.

Emergency response

A process safety analysis is primarily designed to:

Establish safe operating parameters

Select the primary method a cooling tower uses to transfer heat:

Evaporation

Heat exchangers can be found in all of the following categories except:

Fire Tube

List the types of problems a fired heater typically encounters:

Flame impingement, coke buildup, hot spots inside furnace, fuel composition changes

What safety device is designed to evenly distribute the forces of an accidental fall to the strongest muscles in the body, protect vital organs, and limit the possibility of a serious injury?

Full body harness

Heat energy is transferred from areas of:

Hot to cold

Cooling towers are classified by:

How it produces airflow, airflow vs. downward flow of water

How do hazardous chemicals enter the human body?

Inhalation, absorption, ingestion, injection.

Reboilers have two basic designs:

Kettle and thermosyphon

Fluid flow is characterized as:

Laminar, turbulent, parallel, series, counterflow, and crossflow

Furnace draft comes in four designs, list them:

Natural, induced, forced, balanced

Shell and tube heat exchangers can be broken into all of the following except:

Pot belly and kettle reboiler

List the five elements of a control loop:

Primary Elements & Sensors, Transmitters, Controllers, Transducers, Final Control Elements

Describe the purpose of bearings in rotary equipment.

Radial bearings are designed to prevent vertical and horizontal movement of a rotating shaft. Axial bearings are designed to prevent back and forth movement.

__________ and __________ valves are designed to protect systems from over-pressuring.

Relief and Safety

Heat exchangers can be used in all of the following except:

Remove impurities from cold water

Describe the purpose of seals in rotary equipment.

Seals are designed to prevent leakage between internal components in rotating equipment. They keep dirt and water out of lubricant and minimize air leakage into and out of equipment.

What emergency signals should you know before entering a chemical plant or refinery for the first time?

Signal for vapor release, signal for fire or explosion, signal for evacuation.

What happens to a process technician who has experienced hearing loss due to industrial noise?

They will never recover.

Catalytic cracking uses __________ to separate mixtures.

Catalysts

What type of valve is primarily designed for manual throttling service?

Globe valve

What type of valve is primarily designed for open/closed or start/stop service?

Gate valve

What type of valve is primarily designed to prevent reverse flow?

Check valve

Process technology is best described as:

All of the above. A completion of college courses required to be a process technician, study of modern process control, design, and application of manufacturing engineering principles, and the study and application of scientific principles associated with the operation and maintenance of the chemical process industry.
