51312-01209-Use of Ionic Modeling to Gain New Insights on Crude Unit Overhead Corrosion

Crude unit overhead systems contain complex mixtures of hydrocarbon water and various ionic species. Ionic modeling has been used to better understand the rapidly changing phase behavior in this system and to shed some light on some factors which may influence corrosion.

Crude unit overhead systems contain complex mixtures of hydrocarbon water and various ionic species. Understanding the corrosion characteristics of the system is further complicated because the composition and phase behavior of the overhead stream is also changing rapidly as it is being condensed. Ionic modeling has been used to better understand the rapidly changing phase behavior in this system and to shed some light on some factors which may influence corrosion. Ionic modeling of a crude unit overhead system predicts the formation of a concentrated "salty water" phase that preceeds the formation of a bulk water phase. The formation of this concentrated solution may help explain the aggressive corrosion characteristics some amine hydrochloride salts in crude unit overhead systems. Additionally the presence of small quantities of tramp amines may influence the salt formation characteristics and phase behavior of the system.

Key words: Crude unit, overhead, corrosion, amines, amine-hydrochloride salts, ionic modeling, water dew point, salty water phase, salt point
