【Q&A Question 032】Why is it necessary to control the rate of pressure release when reducing the system pressure on February 1, 2018? It is to prevent too rapid pressure release from causing the catalyst to break apart. (Unless otherwise specified, all Q&A questions are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

(1) Prevent excessive pressure release, which could cause the catalyst to break. (2) Prevent damage to equipment and pipelines
Prevent catalyst fragmentation; prevent damage to equipment and pipelines
Prevent too rapid pressure release, which could cause the catalyst to break apart.
1. Excessive speed can easily lead to the accumulation of flammable and explosive gases, resulting in accidents； 2. Failing to control the pressure release rate properly may cause air to flow back into the tank
