摘要： Particulate solids and gas are removed from a three phase hydrocarbon synthesis slurry of solid catalyst particles, gas and liquid, by successively passing slurry from a slurry body through solids and gas disengaging zones in fluid communication, with the solids disengaging zone upstream of the gas disengaging zone. This is accomplished using a solids and gas disengaging downcomer immersed in the slurry wherein solids are disengaged in a quiescent zone adjacent the slurry body, from which the solids reduced slurry passes through an enclosed cup in which gas is disengaged and removed. The bottom of the cup terminates in a downwardly depending downcomer which hydraulically feeds the densified, solids and gas reduced slurry to the bottom of the reactor or to filtration.

摘要： Integrated hydroprocessing methods using high activity, low density catalysts are provided. The high activity catalysts allow for lower temperature operation, which reduces catalyst degradation, while the low density of the catalysts means a corresponding reduction in the amount of metal needed to fill a reactor volume. The methods allow for flexible processing of feedstocks with a variety of wax contents.

摘要： A method of separating a feed stream in a distillation tower. Vapor is permitted to rise upwardly from a distillation section of the distillation tower. A feed stream is introduced into a controlled freeze zone section of the distillation tower, the controlled freeze zone section being situated above the distillation section. The feed stream is released above a level of a liquid retained by a melt tray assembly in the controlled freeze zone section. Vapor from the distillation section is directed into the liquid retained by the melt tray assembly. A solid is formed from the feed stream in the controlled freeze zone section.
