Executive Summary


The Clean Products Upgrade Project (CPUP) included the Isomerization Project at a Washington refinery. The project entailed the replacement of the Naphtha Hydrotreater (NHT) Reactor, revamp of the NHT unit and the installation of a new C5/C6 isomerization (ISOM) unit to support EPA Tier 3 gasoline standards.

We were responsible for the front-end engineering and design (FEED), detailed engineering and procurement.

Client's Challenge


The project scope covered the expansion and debottlenecking of the NHT unit, addition of a C5/C6 ISOM unit and associated impacts to the existing Benzene Saturation (BenSat™) Unit.

The NHT feed rate was increased to 46,000 barrels per stream day, processing more fluid catalytic cracking gasoline to reduce sulfur in the gasoline pool and meet EPA Tier 3 gasoline standards.

A C5/C6 ISOM section was added to the existing BenSat unit at the refinery to process 13,110 barrels per stream day feed and produce a C5/C6 isomerate product.

The isomerate improved the overall octane of the gasoline pool.

Fluor's Solution


Our scope included FEED, detailed engineering and procurement for the Isomerization Project.

We leveraged our global sourcing and fabrication capabilities, providing module erection and pipe fabrication. Nine modules were involved in the NHT/ISOM project with weights ranging from 40 to 120 tons.

The modules arrived complete with piping, mechanical equipment, electrical and instrumentation installed. This improved productivity by reducing work hours on site, building mechanical and civil work concurrently and enhancing quality control. Our solution reduced the overall total installed cost of the project by 17%.

Conclusion


Fluor supported upgrades to a Washington refinery. The revamped NHT unit and the added ISOM unit allowed the refinery to meet EPA Tier 3 gasoline standards.
