Petrochemical production plants are usually operated under high temperature,high pressure,vacuum and other harsh conditions.In actual production,in addition to the strict requirements for processes,the additives needed by the plants are also an indispensable and important part.This article takes a styrene plant by ethylbenzene dehydrogenation as an example to introduce the use of typical additives in the styrene plant.Various adverse factors that may occur during production are avoided to reduce risks such as polymerization and corrosion,thus ensuring the long-term stable operation of the plant and avoiding unplanned shutdowns.
