Neutralising amine selection for crude units Making a proper selection of neutralising amine chemistry is a challenging task

摘要

Even though crude units have been around for a long time,maintaining long term reliable operation continues to be a challenge.The unit design,operating conditions,feedstocks,and corrosion control programme must all work together to achieve reliable operation(see Figure 1).If any part of the system is out of sync,the whole unit will suffer.With constantly changing feedstocks and operating conditions,as well as some unique challenges posed by many opportunity crudes,it can be a challenge to keep everything running properly.The neutraliser system is a critical part of the corrosion control programme on crude tower overhead systems.This article will focus on understanding and applying some basic concepts to the design of neutraliser systems and on some more subtle aspects of neutraliser selection that are often overlooked.
