Problem A large Gulf Coast refinery wanted to expand Crude Unit, Vacuum Unit, Naphtha Hydrotreating, Reforming, and Kerosene Hydrotreating capacity Solution Polaris Engineering provided test runs, operational recommendations, and complete designs to deliver desired unit capacities. The work was field-intensive, not simply computer designs performed from the Home Office. More than 50% of the claimed benefits from the work were from implemented operational changes, as opposed to benefits from increased throughput that were gained.
Problem With crude feed slates becoming heavier over time, the client’s capabilities of recovering diesel and atmospheric gas oil became limited with the existing Atmospheric Crude Distillation Towers. As a result they were not able to recover a small portion of diesel and large portion of Atmospheric Gas Oil from the Atmospheric Tower Bottoms (ATB). Thus, these products were downgraded to No. 6 Oil. Solution Polaris proposed the design of a Vacuum Distillation Tower that would not only recover the Diesel Cut and Atmospheric Gas Oil, but also increase Gas Oil yields further to meet Low Sulfur Vacuum Gas Oil […]
Problem A small Gulf Coast refinery had been dormant for over 4 years. The infrastructure, as well as the main processing units, had fallen into disrepair. The new ownership desired to run a different feedstock as well as different product slate than ever had been produced from the refinery. Solution Polaris Engineering provided designs for refurbishing the refinery as well as modifying the processing equipment to produce the new product slate. Polaris Construction provided fabrication, field services, and general contracting to perform the complete refurbishment of the plant. In seven months, the plant went from being dormant to producing on-spec […]
