Which risk increases to a cracking tower when the feedstock's sulfur content exceeds the desulfurization unit capacity?

A)Increased rate of pitting corrosion✓

B)Reduced catalyst half-life initially only

C)Decreased product yield from oxidation

D)Elevated hydrogen concentration initially only

💡 Explanation

Increased sulfur causes accelerated pitting because sulfidation corrosion, a form of oxidation, occurs at a high rate when protective layers cannot form. Therefore, the corrosion rate increases; rather than yield changes that need an optimal amount of sulfidation for peak reactions happen.
