A FEED NOZZLE ASSEMBLY

摘要

The present subject matter relates to a feed nozzle assembly (100) for atomizing a heavy hydrocarbon feed by mixing the hydrocarbon feed with a diluent and an atomizing media. The feed nozzle assembly (100) includes at least one primary mixing chambers (101) for receiving the liquid hydrocarbon feed and the diluent to create a primary mixture. The primary mixture is than forwarded to a secondary mixing chamber (102). The secondary mixing chamber extends to a tertiary mixing chamber (103). A steam inlet (110) is provided to inject streams of steam to the secondary mixing chamber (102) and to the tertiary mixing chamber (103) through a first opening and a second opening, respectively, located within the steam inlet (110).
