COMPARISON OF DIFFERENT ANALYSIS DESIGN METHODS IN THE CALCULATION OF HYDROGENATION REACTOR SKIRT STRUCTURE

摘要

The skirt support structure of hydrogenation reactor works in the conditions of high temperature and high pressure. There is not only high mechanical stress but also high temperature difference stress in this zone. The service environment of the structure is in poor conditions. In this paper, temperature field analysis on the local structure of skirt hot box is carried out. The stress classification method and direct route method are used to calculate the skirt support structure of hydrogenation reactor. The calculation results are compared. Results of these two analysis and design methods are both meet with the requirements of relevant standards. The results obtained by two methods are discussed. Some meaningful conclusions are obtained.
