This project involved the replacement of an aging nitric acid column and associated infrastructure at an operating production facility in Verdigris, Oklahoma. The work was executed within a live plant environment, requiring careful integration with existing foundations and systems while maintaining uninterrupted operations.

TCE Scope

Tata Consulting Engineers provided front end and detailed engineering for the column replacement on the existing foundation. The scope included integration of the new column with cooling water and process systems, along with the installation of associated pumps, scrubbers, and heat exchangers. The engineering also covered rerouting firewater and drainage systems to align with the updated layout and operational requirements of the facility.

Impact

The project extended the usable life of the nitric acid production unit and improved overall plant performance. The upgrade was delivered with minimal disruption to ongoing operations, allowing the facility to continue production while critical assets were modernized.
