Experimental Investigation of Thermally Induced Vibration in Sulphur Recovery Unit (SRU)
Keywords:hotspot, Sulphur Recovery Unit (SRU), vibration level
Hotspot related problem can be detrimental to Sulphur Recovery Unit (SRU) material lifespan. One of the causes of the hotspot is susceptible high vibration level of multi components in SRU. In this project, the vibration level of the sulphur recovery unit was experimentally measured. The main objective of the measurement is to technically assessed the unit for maintenance management purpose. Two types of measurements were performed. Firstly, bump tests were conducted to accurately determine the natural frequency of the oxygen intake pipeline. Secondly, the vibration level is then mapped to various components in the system according to the process conditions. By analysing this map, the correlation between the vibration levels, natural frequency and process conditions that can cause excessive vibration of the SRU can be specifically verified.
