Troubleshooting experiences have shown that, in the crude oil distillation process, a two-stage overhead system is the type of facility that most often suffers from severe corrosion.
Changing the point of injection of the neutralizing amine is one of four factors that, used together, can reduce corrosion in these systems.
The most common problem Process Improvement Engineering has encountered in performing crude-unit troubleshooting is corrosion-related failure caused by hydrochloric acid (HCl) attack (Fig. 1). Affected components are:
