Operating philosophy can reduce overhead corrosion
Boost refinery reliability by controlling potential amine recycle loops
Salt fouling and associated corrosion in the crude unit
overhead are complex phenomena that impact refinery reliability, flexibility and,
ultimately, profitability. Establishing an appropriate balance
of physical, mechanical and operational parameters, unique to
each unit, is critical to minimizing fouling and corrosion
throughout the crude unit. Factors such as amine chloride salt
points; optimum accumulator pH; and overhead water ICP (initial
condensation point, also referred to as water dew point) are
interrelated and all affect the potential for system fouling
