A critical review of current methods for monitoring the performance of heat exchangers in the presence of fouling highlights a number of pitfalls. An improved analysis method and visualization of operation data (the TH-λ plot) are proposed, which en

A first attempt to characterize intact foulant of a refinery preheater is presented. A tube was removed from an exchanger located postdesalter and preflash-drum at a 4-year shutdown, and dissected into undisturbed cut-out rings. Following visual insp

Pipelines that were well designed for conventional oils may not be able to cope with a transition to heavy oils without some retrofit adaptation, as the increased pressure drop may exceed constraints and force some reduction in throughput. In this pa
