Abstract:

The paper investigates the corrosion of the furnace tube elements of intalatiile Atmospheric crude oil distillation and vacuum of oil. Such phenomena occur in the ceiling and accentuates intalatie distillation as we approach the staging area.

Although the corrosion phenomena is not frequently met for the tubes from the furnace, it produces serious damage because when a tube reached limit corrosion in one spot it must be immediately replaced taking into accomrnt the fact that the remaining tube is in perfect condition.

[EXCERPT]

The fluid flow is biphasic, corrosion processes, as it consisted, depend not so much on the total acidity of crude oil, but on the total acidity of the non-vaporised residue from the system (Table 2). In order here to calculate the total acidity coefficient of the non-vaporised was determined residue efficiency in distilled fractions from native (TAC) of crude oil remaining after each fraction was removed. The data presented in Table 2.2 show that the total acidity coefficient of the non-vaporised residue reaches maximum of 2.56 mg KOH / g corresponding to the fuel oil exiting the furnace.
