System and method for controlling and optimizing the hydrothermal upgrading of heavy crude oil and bitumen
A system and method is provided for upgrading a continuously flowing process stream including heavy crude oil (HCO). A reactor receives the process stream in combination with water, at an inlet temperature within a range of about 60 C. to about 200 C. The reactor includes one or more process flow tubes having a combined length of about 30 times their aggregated transverse cross-sectional dimension, and progressively heats the process stream to an outlet temperature T(max)1 within a range of between about 260 C. to about 400 C. The reactor maintains the process stream at a pressure sufficient to ensure that it remains a single phase at T(max)1. A controller selectively adjusts the rate of flow of the process stream through the reactor to maintain a total residence time of greater than about 1 minute and less than about 25 minutes.
BITUMEN PRODUCTION FROM SINGLE OR MULTIPLE OIL SAND MINES
A process for operating multiple oil sand mine sites for extracting bitumen from oil sand is disclosed, comprising preparing a first conditioned oil sand slurry at a first location using a first oil sand slurry preparation and slurry conditioning process; preparing a second conditioned oil sand slurry at a second location using a second oil sand slurry preparation and slurry conditioning process; combining the first conditioned oil sand slurry and the second conditioned oil sand slurry in at least one slurry distributor to produce a combined oil sand slurry; and distributing the combined oil sand slurry to at least one separation vessel to produce bitumen froth.
PLANT-BASED COMPOSITIONS AND USES THEREOF
The present invention relates to compositions comprising a plant material and methods for using the same. The methods include extracting or removing a substance from a substrate, or remediating a substrate from a substance. The substance can comprise a hydrocarbon-containing substance, a protein, lipid, wax, fatty acid or fatty alcohol, grease, fat, oil or a combination thereof.
Enhanced turndown process for a bitumen froth treatment operation
More particularly, the model was a dynamic simulation built in HYSYS v7.1. The component slate was simplified and selected to give a vapor and two liquid phases, and have the ability to measure an S/B ratio. All the unit operations were included and modeled as best fit within HYSYS. Pumps were all modelled as standard HYSYS centrifugal pumps with performance curves, settlers were modelled as vertical 3-phase vessels with internal weir enabledthe overflow side of the weir is used to simulate the overflow vessels on the settlers. All proposed controllers were included with generic tuning parameters, which control the system process variable (PV) to match a set point (SP). The control algorithm incorporated master PV controllers such as S/B ratio to relate froth and solvent flows and maintain relative material balance relationship between the process streams involved. In this specific simulation, the solvent flows were assigned a slave relationship relative to the bitumen flow; that is, the solvent controller SP was reset based on the bitumen froth flow and the master S/B ratio.
Methods of obtaining a hydrocarbon material from a mined material, and related stabilized emulsions
A method of obtaining a hydrocarbon material from a mined material comprises forming a colloidal dispersion comprising solid particles and a carrier fluid. The colloidal dispersion is mixed with a mined, hydrocarbon-containing material to form an emulsion stabilized by the solid particles. At least one property of the emulsion is modified to destabilize the emulsion. Additional methods of obtaining a hydrocarbon material from a mined material, and a stabilized emulsion are also described.
Method of production of fuels from biomass, from low quality coals and from wastes, residues and sludges from sewage treatment plants
The present invention concerns a method for the removal of inorganic components such as potassium, sodium, chlorine, sulfur, phosphorus and heavy metals, from biomass of rural or forest or urban origin or even mixture of different origin biomasses, from low quality coals such as peat, lignite and sub-bituminous/bituminous coals, from urban/industrial origin residues/wastes, which are possible to include as much organic>5% weightas inorganic<95% weightcharge and from sewage treatment plant sludges. The desired goal is achieved with the physicochemical treatment of the raw material. The method can also include the thermal treatment, which can precede or follow the physicochemical one. The application of the thermal treatment depends on the nature and the particular characteristics of each raw material as well as on the feasibility analysis of the whole process in order to determine the optimization point in each case.
USE OF SURFACTANTS IN WATER-BASED BITUMEN EXTRACTION PROCESSES
A process for extracting bitumen from oil sand ore to produce a bitumen froth having reduced solids is provided, comprising mixing the oil sand ore with water and a first process aid comprising at least one surfactant to form an oil sand slurry; conditioning the oil sand slurry to produce a conditioned oil sand slurry; and introducing the conditioned oil sand slurry into a separation zone for forming the bitumen froth having reduced solids.
BITUMEN DROPLETS COALESCENCE
A process is provided for treating an aqueous oil sand slurry containing bitumen droplets and air bubbles prior to separation in a separator, comprising separating the aqueous oil sand slurry into at least two individual slurry streams and allowing the at least two slurry streams to collide with one another such that the bitumen droplets and air bubbles in each slurry stream make contact with one another to increase both collision frequency and efficiency, and providing sufficient residence time to allow the bitumen droplet to coalesce, grow, and aerate to produce a treated oil sand slurry with larger and lighter bitumen droplets to improve bitumen flotation and recovery.
Process for the recovery of bitumen from an oil sand
The present invention relates to a process for the recovery of bitumen from an oil sand comprising the following phases in succession: (a) mixing an oil sand with a diluent capable of reducing the viscosity and density of the bitumen contained in said oil sand, obtaining a first mixture (slurry) comprising diluted bitumen; (b) mixing said slurry with a basic aqueous solution (BAS) possibly containing salts to increase its ionic strength, capable of removing said diluted bitumen from said oil sand containing it, obtaining a second mixture (BAS-slurry) which can be separated into (i) a liquid phase comprising said diluted bitumen, a fraction of oil sand free of the bitumen removed and water; (ii) a sediment comprising the remaining fraction of said oil sand free of the bitumen removed, water and residual hydrocarbons which can be eliminated by subsequent washings; (c) separating a liquid phase comprising said diluted bitumen removed, from said BAS-slurry mixture; (d) recovering, from said liquid phase separated in phase (c), the removed diluted bitumen contained therein.
Multivalent polymers for clay aggregation
The disclosure relates generally to the use of polymers to assist in aggregating mineral components in aqueous mineral slurries to release and separate individual components of the slurry, which may then be recovered from the slurry.
