Detox Group Plant Operator Interview Questions and Answers

Alcohols are organic compounds with hydroxyl (-OH) functional group. Atomic weight varies depending on the type of alcohol.

• Alcohols can be classified as primary, secondary, or tertiary based on the number of carbon atoms attached to the carbon atom with the hydroxyl group.

• Methanol, ethanol, propanol, butanol, pentanol, and hexanol are some common alcohols.

• The atomic weight of alcohols varies depending on the number of ...read more

Distillation is a process used to separate components of a liquid mixture based on differences in boiling points.

• Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.

• Common examples of distill...read more

Types of pumps include centrifugal, reciprocating, and rotary pumps. Types of valves include gate, globe, ball, and butterfly valves.

• Types of pumps: centrifugal, reciprocating, rotary

• Types of valves: gate, globe, ball, butterfly

• Examples: Centrifugal pump, Gate valve

Distillation is a process of separating components of a liquid mixture based on differences in boiling points. Types include simple, fractional, and steam distillation.

The density of water is approximately 1 gram per cubic centimeter at 4 degrees Celsius.

• The density of water is 1 g/cm^3 at 4 degrees Celsius.

• Density of water varies with temperature and pressure.

• Water is often used as a reference for density calculations.

Human and plant safety is a top priority in our work. We use various safety equipment to ensure a safe working environment.

• Personal protective equipment (PPE) such as hard hats, safety glasses, gloves, and steel-toed boots

• Safety harnesses for working at heights

• Gas detectors for monitoring air quality

• Fire extinguishers and first aid kits for emergencies

• Lockout/tagout devices to prevent accidental start-up of machinery

There are various types of safety permits required for plant operations.

• Work permit

• Hot work permit

• Confined space entry permit

• Electrical safety permit

• Lockout/tagout permit
