就设备和管道设计、材料选择、制造、操作和检查实践向工程和工厂人员提供指导，以管理加氢处理反应器出水系统湿段的腐蚀和污垢。反应器出水系统包括易受铵盐化、NH4HS腐蚀和相关污垢影响的设备和管道。该系统通常从最后一个进料/出水交换器或第一个注水点开始，然后继续通过冷高压分离器（1、2和3分离器设计）或冷高压和低压分离器（4和5分离器设计）。 反应器流出物系统特别排除汽提塔、分馏塔和最终分离部分。然而，本文件中的指南也可能适用于这些区域的铵盐腐蚀缓解。这些系统中的大多数都有空气冷却器；然而，有些系统仅使用管壳式换热器。反应器出水系统容易受到硫化氢铵（NH4HS）和氯化铵（NH4Cl）盐的污染和腐蚀。本推荐规程适用于NH4Cl和NH4HS盐可以形成并沉积在设备和管道中，或溶解在水中形成这些盐的水溶液的工艺流。 本规程包括:劣化机制的细节；评估和监测系统腐蚀性的方法；新工艺和改造工艺的材料选择、设计和设备制造细节；设备维修中的注意事项；以及检查计划的细节。

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. The reactor effluent system includes the equipment and piping subject to ammonium salting, NH4HS corrosion, and associated fouling. This system usually begins at the last feed/effluent exchanger or first water injection point and continues through the cold high-pressure separator (1, 2, and 3 separator designs) or cold high- and low-pressure separators (4 and 5 separator designs). The reactor effluent system specifically excludes the stripper, fractionator, and final separation sections. However, guidance in this document may be applicable to ammonium salt corrosion mitigation in those areas, as well. The majority of these systems have an air cooler; however, some systems utilize only shell and tube heat exchangers. Reactor effluent systems are prone to fouling and corrosion by ammonium bisulfide (NH4HS) and ammonium chloride (NH4Cl) salts.This recommended practice 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. Included in this practice are: details of deterioration mechanisms; methods to assess and monitor the corrosivity of systems; details on materials selection, design, and fabrication of equipment for new and revamped processes; considerations in equipment repairs; and details of an inspection plan.
