CPT Chemical Process Fundamentals & Reactions 3

Question 1

What principle is a distillation process based on in chemical manufacturing?

Accepted Answer

Differences in boiling points (volatilities) of liquid components

Answer

Distillation separates liquid mixtures based on differences in the boiling points (relative volatility) of the components.

Question 2

What is polymerization in a chemical process context?

Accepted Answer

Combining many small monomer units into long-chain polymer molecules

Answer

Polymerization is the chemical process by which monomer molecules react and bond together to form long-chain polymer molecules (e.g., polyethylene from ethylene).

Question 3

What is the primary purpose of a scrubber in a chemical or refining process plant?

Accepted Answer

To remove pollutants or contaminants from a gas stream using a liquid

Answer

A scrubber contacts a gas stream with a liquid (typically water or a caustic solution) to absorb and remove harmful pollutants or contaminants before the gas is released.

Question 4

What critical information is provided by a Safety Data Sheet (SDS) for a chemical used in a process plant?

Accepted Answer

Hazard identification, handling, storage, and emergency response information

Answer

An SDS (formerly MSDS) provides comprehensive hazard information including physical/chemical properties, health hazards, safe handling, storage, and emergency procedures for a chemical.

Question 5

What distinguishes a Brønsted-Lowry acid from a Brønsted-Lowry base?

Accepted Answer

An acid donates protons (H⁺); a base accepts protons

Answer

In the Brønsted-Lowry definition, an acid is a proton (H⁺) donor and a base is a proton (H⁺) acceptor.
