Title:
METHOD AND DEVICE FOR SEPARATING HYDROCARBONS AND CONTAMINANTS WITH A SPRAY ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2015/084494
Kind Code:
A3
Abstract:
A method for separating a feed stream in a distillation tower comprising maintaining a controlled freeze zone (CFZ) section in the distillation tower, receiving a freezing zone liquid stream in a spray nozzle assembly in the CFZ section, wherein the spray nozzle assembly comprises a plurality of outer spray nozzles on an outer periphery of the spray nozzle assembly and at least one inner spray nozzle interior to the outer spray nozzles, wherein each outer spray nozzle is configured to spray the freezing zone liquid stream along a central spray axis, and wherein the central spray axis of at least one of the outer spray nozzles is not parallel to a CFZ wall, and spraying the freezing zone liquid stream through the spray nozzle assembly into the CFZ section to keep a temperature and pressure at which the solid and the hydrocarbon-enriched vapor stream form.
