  • Process having improved base oil yield
    Patent number: 11873455
    Abstract: Provided is a process for preparing base oil from a waxy hydrocarbon feedstock by contacting the hydrocarbon feedstock in a hydroisomerization zone under hydroisomerization conditions. The reaction is in the presence of hydrogen and an inert gas, with the total pressure in the hydroisomerization zone being at least 400 psig. A product from the hydroisomerization zone is collected and separated into base oil products and fuel products. The inert gas can comprise any suitable inert gas, but is generally nitrogen, methane or argon. Nitrogen is used in one embodiment.
    Type: Grant

  • Process to make finished base oils and white oils from dewaxed bulk base oils
    Patent number: 11441085
    Abstract: Provided in one embodiment is an improved and more flexible process for preparing a finished base oil or a white oil product comprising passing a dewaxed base oil product to a distillation column and separating the dewaxed base oil product into fuel and base oil product streams. The base oil product streams are tested to determine if they meet desired specifications. Base oil product streams that meet the desired minimum base oil specifications are passed to a hydrofinishing reactor to prepare a white oil product, or passed to direct sale.

  • Process providing improved base oil yield
    Patent number: 11396631
    Abstract: A process for preparing a base oil from a waxy hydrocarbon feedstock is provided. The process comprises passing the hydrocarbon feedstock to a distillation column prior to dewaxing in order to recover a heavy wax cut. The heavy wax is then hydrocracked to lower boiling compounds which can be better isomerized to a base oil with an acceptable cloud point. The base oil yield is also increased.
