Hydrogen donor solvent production and use in resid hydrocracking processes
InactiveUS20070108100A1Treatment with plural serial cracking stages onlyCoke ovensHydrogenBoiling point
A process derived hydrogen donor solvent is used to increase the maximum resid conversion and conversion rate in an ebullated bed resid hydrocracker. The hydrogen donor solvent precursor is produced by hydroreforming reactions within the resid hydrocracker, recovered as the resin fraction from a solvent deasphalting unit, regenerated in a separate hydrotreater reactor, and recycled to the ebullated bed resid hydrocracker. The major advantage of this invention relative to earlier processes is that hydrogen is more efficiently transferred to the resin residual oil in the separate hydrotreater and the hydrogen donor solvent effectively retards the formation of coke precursors at higher ebullated bed resid hydrocracker operating temperatures and resid cracking rates.

Solvent extraction of hydrocarbons from inorganic materials and solvent recovery from extracted hydrocarbons
InactiveUS6207044B1No pollution to the environmentIncrease surface areaLiquid organic insulatorsWorking-up pitch/asphalt/bitumen by chemical meansHydrocarbon solventsSolvent vapor
A process for the solvent separation of hydrocarbons from tar sand or contaminated soils comprises extracting the hydrocarbons from the sand or soil in a solvent extraction means to form a hydrocarbon rich solvent solution. The rich solvent is separated from the hydrocarbon in a process that utilizes flashing of the solvent in a heated flashing column at ambient pressure. The hydrocarbon is withdrawn from the bottom of the column and the flashed solvent vapors are strategicly withdrawn and passed into a condensation column from which the condensed solvent may be recycled. The flashing column is divided by a series of horizontal, vertically aligned apertured trays. The solution is introduced into the top of the column and the flashing operation is facilitated by the increase in the surface area of the solution as it flows by gravity from tray to tray. The column is maintained at a temperature, preferably above the boiling temperature of the solvent. The process is particularly adapted to the use of chlorinated hydrocarbon solvents and most particularly to the use of methylene chloride.

This is a method to reactively refine hydrocarbons, such as heavy oils with API gravities of less than 20° and bitumen-like hydrocarbons with viscosities greater than 1000 cp at standard temperature and pressure using a selected fluid at supercritical conditions. The reaction portion of the method delivers lighter weight, more volatile hydrocarbons to an attached contacting device that operates in mixed subcritical or supercritical modes. This separates the reaction products into portions that are viable for use or sale without further conventional refining and hydro-processing techniques. This method produces valuable products with fewer processing steps, lower costs, increased worker safety due to less processing and handling, allow greater opportunity for new oil field development and subsequent positive economic impact, reduce related carbon dioxide, and wastes typical with conventional refineries.
