High Temperature Operation

Owing to the high temperature inside a sulfur recovery unit (SRU) thermal reactor, detailed experimental measurements are difficult. In the author’s previous studies, several methods have been assessed to resolve the abnormality of the SRU thermal reactor under high temperature operation. This paper presents a new easier and more economical method. The effects of inlet air quantity and inlet O2 mole fraction on the combustion and fluid flow in a SRU thermal reactor are investigated numerically. The flow field temperature, S2 recovery, H2S mole fraction, and SO2 emissions are analyzed. This paper provides a guideline for adjusting the inlet air quantity and the inlet O2 mole fraction to reduce the high temperature inside a thermal reactor and to ensure an acceptable sulfur recovery.

Experiential Analysis

According to the management and scheduled inspection of pressure vessels and piping in sulfur recovery unit, it described the evaluation of the failure probability and consequences of pressure vessels and piping by the Risk Based Inspection (RBI). This article focuses on the practical application process of RBI to the Sulfur Recovery Unit. Together with the production crafts and loop medium in pressure vessels and pipes, we could dig out high risk equipment and its’ reasons, therefore, suggest possible precautions. Further precautions will be provided for equipment manufacturers to assure production safety through personal experiential analysis and comparison with the similar product from the aspect of failure mechanism and position. It is aimed to explore the combined method of RBI and personal experiential analysis and it’s practical application.
