  • Patent number: 8864981
    Abstract: Deasphalted residual oil (DAO) and the aromatics-rich extract that is derived from DAO have low polycyclic aromatics contents, relatively low aniline points, and high flash points. They form blending stocks that improve properties of mixed feedstocks to consistently produce environmentally qualified rubber processing oil (RPO) by extraction under low solvent-to-oil ratios and moderate extraction temperatures. Distilling a petroleum crude oil under atmospheric pressure generates a bottom residual oil which is then subject to vacuum distillation to yield a bottom residual oil. DAO is produced by removing the asphalt from the vacuum bottom residual oil through extraction with light paraffinic solvent. The extract of DAO is a co-product in the production of the bright stock of the lubricating oil through extraction. The feedstock is mixed with the extract from a petroleum fraction boiling in lube oil range.

  • Patent number: 8609429
    Abstract: Methods for determining the fouling propensity of a hydrocarbon stream and for reducing fouling are provided. In one method, the fouling propensity of a hydrocarbon stream is determined by obtaining a parameter value indicative of the fouling propensity at no less than two different temperatures, and an activation energy of fouling by the hydrocarbon stream is derived therefrom. In another method, the thus obtained parameter value at no less than two different temperatures and the activation energy are used to select proper heating fluids and operating temperature and to determine whether to add an antifoulant to the hydrocarbon stream to reduce fouling at a given temperature.

  • Publication number: 20130313160
    Abstract: Disclosed herein are methods for isolating heavy saturated hydrocarbons from a subsurface shale formation comprising kerogen and an extractible organics component. These methods can be used to provide a bright stock product. The process comprises extracting an extractible organics component from subsurface shale formations comprising kerogen and the extractible organics component in an inorganic matrix and isolating a heavy hydrocarbon fraction comprising saturated beta-carotene. The methods utilize a hydrocarbon solvent to at least partially solubilize the extractible organics component. Among other factors, these processes are based on the discovery that the extractible organics is composed of a heavy hydrocarbon component containing saturated beta-carotene. The saturated beta-carotene product is a valuable commercial product. The presently disclosed processes are more environmentally benign, more economical, and more efficient in producing commercial products and in providing access to kerogen.

  • Patent number: 8540869
    Abstract: A method for forming a finished lubricant comprises selecting a target high temperature viscosity for the finished lubricant. A target high temperature viscosity for a base oil blend is selected. The target high temperature viscosity for the base oil blend is less than the target high temperature viscosity for the finished lubricant. At least two base oils from at least three viscosity grades of base oils are selected and mixed to form a base oil blend that meets the target high temperature viscosity for the base oil blend. The base oil blend is mixed with performance additive package and viscosity modifier to provide a finished lubricant that meets the target high temperature viscosity for the finished lubricant. The at least two base oils for the base oil blend having the target high temperature viscosity are selected such that less viscosity modifier is needed to meet the target high temperature viscosity of the finished lubricant.
