Examination of design temperature allowance on creep range piping
This article delves into the effects of providing standard design temperature allowances for piping systems operating in the creep range. The aim of examining this practice is to enhance the understanding of its implications for pipe engineering.
SMR feed effluent hairpin exchanger: Once upon a time—An unusual thermal mix-point failure—Part 1
This article presents a review of a failure that happened in a hairpin heat exchanger type on the shell side in a hydrogen (H2) reformer unit. This mechanism was not identified during the design phase and led to a failure after only two years of operation. This article also reviews the situations encountered during the design stage and how they affected the material selection.
Refinery/petrochemical makeup water treatment: A general guide for technical personnel—Part 3
A very important—and sometimes overlooked—unit operation within hydrocarbon processing facilities is makeup water treatment for steam generators and other processes. Many cases have been documented in which makeup system upsets have led to boiler tube failures that partially or completely shut down unit processes. The three parts of this article (August, September and October 2024) serve as a guide for those employees who may be on a steep learning curve when it comes to makeup system understanding.
