Abstract:
1. A process for separating solids from a vapor, the process comprising: feeding a vapor mixture comprising hydrocarbons and entrained solids to an inlet of a solids separation device, the solids separation device comprising: spraying a hydrocarbon fluid through the at least one inlet nozzle into the vessel, thereby forming a thin film of hydrocarbon fluid on the indirect heat exchange device; condensing at least a portion of the hydrocarbons in at least one of the cylindrical portion and the angled portion, thereby forming a film of hydrocarbon fluid on an interior surface of at least one of the cylindrical portion and the conical portion; contacting the solids with at least one of the hydrocarbon film on the cylindrical portion, the hydrocarbon film on the angled portion and the hydrocarbon film on the indirect heat exchange device; recovering a vapor having a reduced solids content and a hydrocarbon-solid mixture via the outlet located at the bottom of the angled portion.
