Question

In ammonia production process which factor increased the pumping cost?

(a) High pressure vessel

(b) Higher space velocity

(c) Low pressure vessel

(d) Lower space velocity

This question was addressed to me during an interview.

This key question is from Inorganic Chemical topic in division Inorganic Chemical Industries of Chemical Technology

Answer 1

The correct answer is (b) Higher space velocity

Best explanation: In ammonia production in addition to higher space velocity, cooling the bed increased the cost of NH3 recovery and pumping cost as well. Using of high pressure vessel increased the cost of reactor.
