Mechanical Integrity of PFHE in LNG Liquefaction Process

Abstract

The mechanical integrity of heat exchangers is the result of an interplay of many physical phenomena. A full, albeit simple, model, that covers mixture phase thermodynamics, heat transfer, flow dynamics, and the thermal and pressure stresses has been created. Using this simulation model it is now possible to quantify the magnitude of different effects. The focus has been on internal instabilities under stationary operations.
