Hexion – Relief Calculations

Background

Hexion Inc., previously Momentive Specialty Chemicals Inc., is a chemical company based in Columbus, Ohio. It produces thermoset resins and related technologies and specialty products. Hexion is organized into two divisions: The Epoxy, Phenolic and Coating Resins Division, and the Forest Products Division.

Solution

Haden Freeman was awarded the contract to undertake pressure relief calculations for the steam systems at Hexion, Peterlee. This was necessitated by the increase of the system operating pressure hence the increase in design pressure for all downstream equipment. HFL undertook physical property calculations, relief flow calculations and relief valve sizing.
