As part of ExxonMobil’s global technology team, Sam Yang is an engineer at the ExxonMobil Singapore Chemical Plant, where he has been working on uncovering opportunities to improve efficient and reliable operations in the olefins processing operations. He joined ExxonMobil Singapore almost 10 years ago since graduating from the National University of Singapore with a Bachelor’s degree in Chemical and Biomolecular Engineering in 2011.
Singapore Chemical Plant Blowdown Modifications
Synopsis: Steam cracking operations at the Singapore Chemical Plant involves the usage of dilution steam that has been generated from a portion of the process condensate. This is subsequently topped up with on-purpose make-up steam to meet the needs of the plant. Through this project, some of the process condensate bypasses the dilution steam generation system and is directly sent to the wastewater treatment system. This allows more condensate to be boiled off as dilution steam, resulting in less make-up steam and, by extension, less energy needed.
