Abstract:
1. An arrangement for feeding a mixture of bitumen and steam to a reactor for further processing of atomized bitumen within the reactor comprising: an atomizing nozzle connected to a wall of said reactor and opening to an interior of said reactor, said nozzle being adapted to atomize bitumen carried by steam into droplets suitable for such further processing; a main conduit having a main axis, connected at a proximal end to said nozzle and including openable closure means at a distal end thereof; a first feed conduit having a first axis and connected to a source of bitumen, said first conduit being in a first plane containing said main and first axes, said first feed conduit joining said main conduit at an angle in the range of 30° to 60° as defined between said main and first axes upstream of the junction between said main and first conduits; a second feed conduit having a second axis and connected to a source of steam, said second conduit being in a second plane containing said main and second axes, said second feed conduit joining said main conduit upstream of the junction between said main and first conduits at an angle in the range of 20° to 40° as defined between said main and second axes upstream of the junction between said main and second conduits; and flow-accelerating nozzle means positioned in said second feed conduit upstream of the juncture between said main and second conduits.
