【Q&A Question 170】June 19, 2018: Briefly explain why it is necessary to control the rate of pressure release when reducing the system pressure. This is to prevent too rapid pressure release, which could cause the catalyst to break down and lead to equipment leaks. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Prevent too rapid removal, which could cause the catalyst to break apart
1. Take into account the requirements of the equipment itself regarding the speed of pressure buildup and release, in order to prevent rapid pressure drops that could cause damage to the containers or equipment or lead to leaks at the flanges； 2. To protect the catalyst bed, a too rapid drop in pressure may cause the catalyst to be crushed or the bed to collapse ； 3. The pressure tolerance requirements for the circuit downstream of the flare or pressure relief valve are generally not high; rapid and excessive pressure release may affect this downstream circuit.
