FLUID INJECTION NOZZLE FOR FLUID BED REACTORS

WIPO Patent Application WO/2011/150012

A3

The liquid feed nozzle assemblies for a circulating fluid bed reactor comprise (i) a throttle body premixer (13) to combine liquid feed (22) with atomization steam (23, 24) upstream of a nozzle body to form a liquid feed/steam mixture comprising liquid feed droplets; (ii) a conduit (15) connected to the venturi premixer (13) and to a discharge nozzle body (29) to convey a flow of the liquid/steam mixture created by the premixer (13) to the nozzle body (29); (iii) a discharge nozzle (29) connected to the flow conduit (15) to shear the liquid feed/steam mixture to create liquid feed droplets of reduced size and (iv) a disperser at the outlet of the discharge nozzle to provide a spray jet of liquid feed having an increased surface area relative to a cylindrical jet. The nozzle assembles are particularly useful in fluid coking units using heavy oil feeds such as tar sands bitumen.
