Challenge
Due to historic crevice corrosion at the inlet gas pass, the client required the refurbishment of a high pressure gas cooler.
The Glacier Energy team carried out a complete deconstruction of the tube bundle followed by a technical survey.
Solutions
Glacier Energy proposed and procured a new forged shell side tube sheet to replace the oil tube sheet to rectify the issues. Mid way through the process, a Computational Fluid Dynamics (CFD) review was carried out.
Due to the pressure differential in the cooler, Glacier Energy carried out a finite element analysis (FEA) and proposed a design modification that would redirect cooling water via the high temperature inlet pass at the tube plate.
