A process for treating a bitumen froth comprising bitumen, solids and water to produce a deasphalted oil product is provided comprising optionally diluting the raw bitumen froth with a diluent to form a diluted bitumen froth; separating the raw or diluted bitumen froth into a light bitumen fraction and a heavy bitumen fraction comprising bitumen, fine solids and water; mixing the heavy bitumen fraction with a first solvent to form a solvent/bitumen mixture; and introducing the solvent/bitumen mixture into a first extraction vessel operating at a temperature and a pressure such that the solvent is at or near supercritical conditions to form a heavy phase comprising asphaltenes, solids and water and a light phase comprising deasphalted oil.

The invention relates to a centrifugal separator comprising a rotor arranged to be rotatable around an axis of rotation (x). An inlet chamber is formed in the rotor and an inlet pipe extends into the rotor and has an opening in the inlet chamber for supply of a liquid mixture of components. An inlet arrangement is provided in the inlet chamber, comprising a set of annular discs coaxial with the rotor and forming passages for liquid between the discs, or a helically shaped element coaxial with the rotor and forming passages for liquid between the windings of the helically shaped element. The separator further comprises vanes arranged upstream of the inlet arrangement such as to cause a pre-rotation and pre-acceleration of the liquid mixture. The vanes may be provided on a removable element of the rotor.

A method of detecting E-line loss in a disc stack centrifuge is provided, comprising: collecting data from at least one instrument associated with the centrifuge over a specific time period; calculating one or more indicators by comparing the collected data with expected values from a normally operating centrifuge, the indicators being indicative of a start of an E-line loss event; calculating the probability of E-line loss by applying weighted voting to the indicators to yield a probability value; and activating an alert upon determination that the probability value exceeds a threshold value.

A method, apparatus and system for obtaining a sample of a fluid solids, such as a coke and hydrocarbon mixture, from a fluid solids process is provided. A sample vessel is provided that contains a first end, a second end, an aperture in the first end and an interior cavity. A cooling device can be provided for cooling material in the interior cavity of the sampling vessel. In operation, fluid solids can be routed through the aperture and collected in the interior cavity. The collected sample material can then be cooled by the cooling device and used for testing.

Fouling in the scrubber section of a fluid coker unit is reduced by providing perforated baffles to improve the uniformity of the gas flow profile in the scrubber by reducing the gas velocity of the cyclone outlet gases in the scrubber section of the unit. These baffles are located with the objective of reducing the rotational component of the gas flow in the scrubber created by the alignment of the gas outlets of the cyclones. The baffles are preferably located in the shed section of the scrubber and comprise upstanding perforated plates located at the periphery of the scrubber section to disrupt high velocity gas jets in the region of the interior wall of the scrubber.
