New Hydrogen (H2) Unit Offsites Installation


gas processing plant

A refinery owner required additional hydrogen to comply with federal specifications to process low sulfur diesel fuel. The refinery owner and a gas supplier contracted to jointly own and operate a hydrogen plant at the refinery. The hydrogen plant needed to be designed and constructed around the refinery's existing conditions to supply the additional hydrogen needed to process the diesel fuel and fulfill federal regulations.


Valdes provided the detail and front-end engineering for the needed infrastructure improvements that were required to support the new hydrogen plant, as well as the utility and piping tie-ins necessary to operate the plant. Some of the deliverables included providing procurement services, developing plot and piping plans which depicted the location of the H2 unit, designing two main switchgears and developing two design packages, IFA and IFC, to include a detailed project scope of work to govern the trade labor activities for this project.


Despite this project presenting with various challenges, especially many unknowns regarding site-specific factors, Valdes was able to assess the existing conditions and complete the detail engineering services on schedule which allowed construction to begin on-time. Over the course of the project, the Valdes team devoted 20,000 hours to deliver the design needed to help the client meet federal requirements.
