The ULSD Solution Model~SM - A Collaborative Approach

摘要

If anything was learned from the gasoline phase of Clean Fuels, it was that decisions to proceed with these projects are frequently postponed or reevaluated. These delays imposed schedule compression and execution issues on the service industries. Whereas the gasoline phase of Clean Fuels was earmarked by technology selection and single stream consideration; the diesel clean fuels will deal with multiple streams and multiple configuration options involving either revamp of existing facilities, a grass roots unit or a combination of both. New units are likely to be more expensive, projects will take longer to develop, and will require intensive collaboration to define. Consequently, the diesel phase will be even more demanding on project execution. Clearly, a better approach was needed to address the compressed schedules associated with the ULSD market. Fluor's ULSD Strategy was the development of a process model linked to OptimEyes?, Fluor's 3D Modeling program, as a screening tool for evaluating hydrotreating options and development of a new work process that facilitates an 18 month execution schedule. Key to the development of the model was a joint effort between Fluor and Akzo Nobel in which Akzo Nobel provided operating parameters for a range of feedstocks and operating conditions. Fluor utilized this data to develop equipment and piping sizing, capital cost and operating cost correlations for incorporation into the model. The model is a collaborative tool suitable for use through design definition bringing the catalyst supplier, engineering contractor and owner together during the conceptual design and providing the platform for early involvement of equipment suppliers, detailed design and construction disciplines in the design phase.
