The Challenge
A leading specialty chemicals manufacturer sought to significantly reduce its greenhouse gas (GHG) emissions and improve thermal efficiency at one of its primary manufacturing facilities. The plant's complex infrastructure - comprising multiple boiler systems, extensive steam and condensate networks, incinerators, and thermal-oil heaters - presented interconnected energy challenges. The site needed a holistic understanding of its energy baseline to identify high-impact reduction opportunities.
Beyond identifying inefficiencies, the facility required actionable, data-driven pathways to reduce steam consumption and improve condensate return. Plant leadership also needed accurate, up-to-date spatial data to streamline future capital-project planning and support long-term modernization and decarbonization goals.
