Abstract
A discussion on crude/vacuum distillation fouling presented at the 56th Annual NPRA Technology Q&A (2002, Philadelphia, PA) covers dominant factors affecting coking in crude and vacuum heaters outlet temperature, peak flux, percent vaporization, velocity, residence time, or other; low cost, effective ways to reduce coking, such as steam injection, oil recycle, additives, or tube coatings; current approaches or technologies used for processing crudes containing calcium naphthanates; impacts of calcium naphthanates in the refinery; strategies developed to address the problems that can result from blending incompatible crudes; methods used to monitor fouling in the crude preheat exchanger train; advancements made in process side low and high temperature corrosion monitoring; and the detrimental effects on desalting, fouling, and corrosion in atmospheric and vacuum units due to processing high total acid number crudes.
