Single vs Multiple Injection Points for REAC Wash Water Systems ...
2016年3月6日 · This paper will examine how the extent of wash water vaporization, coupled with non-equilibrium and liquid maldistribution (free water and oil), impact the risk of corrosion. The results provide a rationale for selecting between single and multiple injection points - or both - based on operating conditions and potential localized peak ammonium ...
Wash Water Injection in Hydroprocessing Units
2023年8月19日 · Wash water is injected to minimize ammonium salt fouling before Reactor Effluent Air Cooler (REAC) and before the last Reactor Feed/Reactor Effluent Exchanger. The wash water injection point is usually located upstream of …
WASH-1400 – The Reactor Safety Study – The Introduction of …
2021年3月24日 · The lecture on November 9 featured both historical knowledge from Dr. Wellock and primary source information from Dr. Budnitz, who participated in the review of WASH-1400 in the mid 1970s. For completeness, the preparer expanded on the material presented on November 9 to ensure sufficient context for readers who may not be familiar with the topic.
Design of Hydroprocessing Effluent Wash Water Systems
1998年3月22日 · To keep salts from crystallizing and depositing on piping and equipment, water wash systems are designed to dissolve the salts into an aqueous phase before the reactor effluent stream is cooled below the salt deposition temperature.

Implementation of Best Practices for Water Washes in
2003年3月16日 · This paper describes a systematic approach that is used to diagnose and mitigate corrosion problems in hydroprocessing unit reactor effluent air cooler systems. The methodology is based on an extensive evaluation of hydroprocessing water wash best practices and addresses both design and operational issues by using state-of-the-art process ...
Treatment of the railway freight wagon wash effluents by …
The use of pre-oxidation with aqueous solutions of hydrogen peroxide or peracetic acid coupled with coagulation based only on aluminum coagulants helps to achieve equal levels of removal of the basic indicator values and a sanitary clean stream of pretreated wastewater (PW) with a colony forming unit (CFU) of <100 ml −1.
WASH-1400 represented a watershed event for the development and use of risk assessment in the nuclear industry. The events documented in this booklet encapsulate the movements surrounding the development of WASH-1400, how WASH-1400 became a proof of concept for the application of risk assessment, and how risk assessment has influenced nuclear power
Nuclear reactor operations were recognized from the very first days of the Manhattan Project as being potentially hazardous. Sites for the early reactors were chosen with remoteness from population centers as one of the requirements. The principal hazards result …
