Question

Valves are an important part of any high-pressure operation.

(a) True

(b) False

The question was posed to me during an interview for a job.

I would like to ask this question from Hydrogenation in section Hydrogenation of Unit Processes

Answer 1

Correct answer is (a) True

The explanation is: Valves are an important part of any high-pressure operation, and in coal hydrogenation they have to withstand hydrogen embrittlement, corrosion, creep at high temperatures, and erosion from solid-liquid mixtures at temperatures of 1000°F and pressures of 10,000 psig.
