    Abstract: The invention relates to an improved mixing arrangement for, primarily, moving bitumen in steam from sources of such bitumen and steam to a reactor or coker for further processing of the bitumen into petroleum products. The invention provides a main conduit connected to an atomizing nozzle mounted in a wall of the reactor and first and second conduits for flowing bitumen and steam respectively into the main conduit. The first conduit is angled relative to the main conduit at an acute angle of about 45° and the second conduit is angled relative to the main conduit at an acute angle of about 30°. The second conduit is positioned upstream of the first conduit by a short distance of about 23 mm and may be angled radially relative to the first conduit by any angle, although a 90° angle is preferred. A flow accelerating nozzle is located in the second conduit adjacent the entrance therefrom into the main conduit The arrangement of the invention improves the flow characteristics of 2-phase material flowing to the atomizing nozzle, reducing pulsations in the main conduit and improving the resulting atomization of the bitumen in the reactor.

    Abstract: In a method of agglomerating carbonaceous coal comprising first agglomerating impurity liberated carbonaceous coal, from an impurity liberated coal slurry, with agglomerating oil to form open structured, chain-like, micro-agglomerates and then forming relatively larger, less open structured more robust agglomerates from a portion of the slurry to provide a mixture of micro-agglomerates, relatively larger, more robust agglomerates, water and any inorganic impurities that may be present. The relatively larger, more robust agglomerates are screened and then the micro-agglomerates are separated using an aerating, skimmer tank leaving an inorganic impurity laden waste water. The micro-agglomerates are rendered buoyant by the aeration and are thus rendered separable from the inorganic laden waste water which may be further treated to remove the inorganic waste to provide water for recirculation.

    Abstract: A wear resistant atomizing nozzle assembly is provided having an outwardly diverging, frustum of a cone-shaped deflector core of wear resistant ceramic and a nozzle rim of wear resistant ceramic and having an outwardly flared inner surface encircling the core to form a flared, atomizing nozzle orifice therewith. The core is mounted in a flared socket of a deflector core holder and inner and outer sleeves feed, say, atomizing air to the deflector core surface and, say, a coal liquid mixture fuel inwardly around the nozzle rim so that the fuel is held by the air as a film against the nozzle rim inner surface and then atomized as it emerges from the nozzle rim.

    Abstract: An atomizing nozzle primarily designed for agricultural spraying has a narrow and controlled droplet size distribution and the ability to shape the spray into a solid cone or fan for evenly applying the spray to the crops. The nozzle is able to operate at low air delivery pressures, in the order of 10 to 30 in. of water column. A central air delivery bore communicates with an air manifold within a boom. Near the exit plane of the throat there is provided an inlet conduit connected to the liquid to be sprayed, the conduit being at right angles to the bore axis. An outlet nozzle from the conduit is positioned on the bore axis and has its exit plane upstream of the exit plane of the bore so that atomization of the liquid will take place within the central bore between the two exit planes. A pair of shaping nozzles are connected to secondary bores that in turn communicate with the manifold. The shaping nozzles are directed orthogonally to the central bore axis and to the inlet conduit and are located downstream of the exit plane of the central bore. The jets issuing from the shaping nozzles shape the cone-shaped spray into a generally fan-shaped configuration. Because the shaping jets are always at the same pressure as the atomization air the dispersion of the droplets exiting the nozzle will be consistent and the spray pattern will be constant over the operating pressure range of the apparatus.

    Abstract: An atomizing nozzle assembly is provided having an outwardly diverging frustrum of a cone shaped, deflector core of wear resistant ceramic, a nozzle rim of wear resistant ceramic encircling the core and coextensive with a downstream portion thereof to form a mixing zone therewith for receiving liquid-to-be-atomized therein from an unobstructed passage and atomizing fluid directing the liquid-to-be-atomized away from the core. The mixing zone leads to a nozzle orifice outlet. The core is mounted in a core holder and is adjustable by a screw thread, in close proximity to the mixing zone, to adjust the width of the mixing zone. The liquid-to-be-atomized (e.g. a coal slurry fuel) and the atomizing fluid (e.g. air) are fed along coaxial tubes which are slidably mounted by glands to accommodate differential expansions.
