API Bull 932-B Design, Materials, Fabrication, Operation, and Inspection Guidelines for Corrosion Control in Hydroprocessing Reactor Effluent Air Cooler (REAC) Systems, First Edition
standard by American Petroleum Institute, 06/01/2004
More info
Full Description
This recommended practice provides guidance to engineering and plant personnel on equipment and piping design, material selection, fabrication, operation, and inspection practices to manage corrosion and fouling in the wet sections of hydroprocessing reactor effluent systems.
RP 932-B is applicable to process streams in which NH4Cl and NH4HS salts can form and deposit in equipment and piping, or dissolve in water to form aqueous solutions of these salts.
An understanding of the variables impacting corrosion and fouling in these systems is necessary to improve the reliability, safety, and environmental impact associated with them. Within the refining industry, continuing equipment replacements, unplanned outages, and catastrophic incidents illustrate the current need to better understand the corrosion characteristics and provide guidance on all factors that can impact fouling and corrosion in REAC systems.
