A kettle reboiler includes a shell, a liquid reservoir defined within the shell to contain a first process fluid, and a tube bundle positioned within the liquid reservoir and at least partially submergible in the first process fluid, the tube bundle being configured to circulate a second process fluid that causes the first process fluid to boil and discharge a vapor-liquid mixture. A liquid-vapor separation assembly is positioned in the shell and includes a separation deck, and a plurality of separation devices mounted to the separation deck, each separation device being operable to de-entrain liquid from the vapor-liquid mixture and discharge a vapor. A vapor outlet nozzle is coupled to the shell to receive the vapor discharged from the plurality of separation devices.

Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any 'pitch' generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

Vane type mist eliminator segments are arranged in a plurality of tiers at separate vertically spaced locations in a tower, typically of the upright, cylindrical type, with the eliminator at each tier covering only a portion of the cross section of the tower. The eliminator segment(s) in each tier are laterally displaced in the tower from the adjacent vertically spaced eliminator segments to form a staggered configuration for the segments. Each mist eliminator preferably extends over 50-70% of the cross-sectional area of the tower to leave an open flow passage in the tier; the staggering of the segments and the associated flow passages defines an upward tortuous or zig-zag open flow path for vapors ascending the tower through the open flow passages when the eliminator segment(s) become fouled in use.
