Assertion (A): Reheat is used after a wet scrubber.

Reason (R): The cooled gas has fallen below its acid dew point and has lost almost all its buoyancy.

Select the correct answer from the options below.

  • A.Both A and R are true, and R is the correct explanation of A
  • B.Both A and R are true, but R is not the correct explanation of A
  • C.A is true but R is false
  • D.A is false but R is true

Answer: A

Correct answer: Both A and R are true, and R is the correct explanation of A

Reheat answers both consequences of wet scrubbing at once: it lifts the gas back above its acid dew point, protecting the lining, and restores some of the buoyancy the cooling destroyed. The reason therefore explains the assertion completely.
