  • Patent number: 10066171
    Abstract: A continuous, hot vapor stripping process recovers base oil from used lubricating oils (ULO) containing lubricating oil boiling range material, with further refining using solvent extraction to produce a high quality base oil. The ULO is charged to a first stripping column along with a stripping vapor to vaporize lubricating oil boiling range components, which are fed to a second stripping column to separate diesel boiling range material from the lubricating oil boiling range components. A lubricating boiling range material is removed as a bottoms product and fed to a liquid-liquid extractor to produce a raffinate stream and an extract stream. The raffinate stream is fed to a raffinate distillation column, where a base oil product is recovered as a bottoms stream. The extract stream is fed to an extract distillation column, where an aromatic oil product is recovered as a bottoms stream.

  • Patent number: 8828218
    Abstract: This invention provides methods for multi-stage hydroprocessing treatment of FCC naphthas for improving the overall production quantity of naphtha boiling-range materials during naphtha production for low sulfur gasolines. Of particular benefit of the present processes is the selective treating of cat naphthas to remove gums instead of undercutting the overall naphtha pool by lowering the end cutpoints of the cat naphtha fraction. This maximizes the amount of refinery cat naphtha that can be directed to the gasoline blending pool while eliminating existing processing problems in hydrodesulfurization units. The processes disclosed herein have the additional benefit of minimizing octane losses in the increased naphtha pool volume.

    Abstract: Process for the continuous hydrogenation of triglyceride containing raw materials in a fixed bed reactor system having several catalyst beds arranged in series and comprising hydrogenation catalyst. The raw material feed, hydrogen containing gas and diluting agent are passed together through the catalyst beds at hydrogenation conditions. The raw material feed stream as well as the stream of hydrogen containing gas are divided into an equal number of different partial streams. These are each passed to one catalyst bed in such a manner that the weight ratio of diluting agent to raw material feed is essentially the same at the entrance of all catalyst beds and does not exceed 4:1. The claimed process is preferably conducted at low temperatures and allows the utilization of existing units due to the low recycle ratio. Further, a sufficient excess of hydrogen is used so that no valuable product is lost through decarb-reactions.
