Abstract: A method of determining a risk state for a complex industrial process includes graphically depicting a process flow diagram on a graphical user interface with a computer system, the process flow diagram including one or more side streams of the complex industrial process, monitoring one or more process parameters of the one or more side streams, and calculating a risk state for each side stream with the computer system based on the one or more process parameters. The risk state of each side stream is then graphically depicted on the process flow diagram by assigning a probability indicator to each side stream based on the risk state calculated by the computer system, wherein the probability indicator comprises a graphical output recognizable by a user and corresponding to a predetermined scale of failure probability.

Abstract: Methods are provided for upgrading disadvantaged feeds for use in lubricant base stock production. A disadvantaged feed can be upgraded by hydroprocessing the feed to form a hydroprocessed bottoms fraction. The hydroprocessed bottoms fraction can then be used as a feed for forming Group I and/or Group II lubricant base stocks, optionally in combination with a conventional feed for lubricant production. The remaining portions of the hydroprocessing effluent can optionally be used for FCC processing and/or for other conventional applications of naphtha and distillate fractions.

Abstract: Methods are provided for rapidly characterizing a feedstock being considered for lubricant base oil production in order to determine the viscosity index potential of the feedstock. It has unexpectedly been discovered that the DDVI value for a feedstock at a specified pour point can be predicted based on a) the feed distillate residual wax content at a temperature as determined by Differential Scanning Calorimetry, such as the feed distillate residual wax content at a temperature corresponding to the specified pour point temperature; b) the feed distillate refractive index; c) the feed distillate kinematic viscosity at a temperature, such as kinematic viscosity at 100° C.; and d) the distillate volume-averaged boiling point. Based on this unexpected correlation, the VI potential of a feedstock can be determined based on measurement of properties that can be performed on a time scale corresponding to one or a few days using a few milliliters of feedstock.

Abstract: Methods are provided for characterizing crude oils, crude fractions, or other potential feedstocks for forming lubricating base oils in order to determine the suitability of a feedstock for lubricating base oil production. One type of characterization is to determine the isoparaffin, naphthene, and/or aromatics contents of the distillate portion of a feedstock. A second characterization is to determine the viscosity index of a distillate portion of a feedstock after dewaxing the distillate portion to a target pour point.

Abstract: Systems and methods are provided for modifying or selecting processing conditions for bright stock formation based on compositional characterization of the feedstock and/or bright stock products. In some aspects, the compositional information can include Z-class characterization of the components of a feed and/or bright stock product, optionally in combination with carbon number and/or molecular weight for the components. The compositional information can be used to select processing conditions to allow for removal and/or modification of selected components within a bright stock in order to improve throughput and/or provide desirable cold flow properties.
