摘要： In an upflow reactor for reacting heavy hydrocarbons with hydrogen gas in a liquefied catalyst slurry, that mixture is recirculated down through a downcomer having an upper degassing section which includes a frusto-conical upper surface. The mixture is caused to flow along that surface in a downward helical path, such that heavier components are centrifugally urged outwardly, and lighter components, e.g., gas, migrate inwardly. The gas bubbles can thus coalesce such that small bubbles become bigger bubbles having a greater tendency to rise out of the downcomer. Baffles placed on the upper surface can maximize the residence time of the mixture in the degassing section.

摘要： Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.

摘要： The invention provides a method and apparatus for producing nitrogen trifluoride. The invention involves passing a working fluid through a heat engine cycle and using the mechanical energy generated by the working fluid to produce sufficient mixing intensity within a nitrogen trifluoride reactor. The method utilizes a working fluid vapor jet, such as a hydrogen fluoride vapor jet, to impart sufficient energy to the mixing zone of a reactor in order to disperse gaseous fluorine within a liquid ammonium acid fluoride melt. A gaseous reaction product stream is removed from the reactor, the reaction product stream comprising nitrogen trifluoride and a working fluid vapor. The working fluid is then separated from the nitrogen trifluoride and recycled for reuse in the process, thereby completing a heat engine cycle.

摘要： An apparatus for a hydrocarbon reforming process includes a combustion chamber, a convection chamber in fluid communication with the combustion chamber, at least one burner disposed in the combustion chamber, a reaction chamber, a means for flowing a first mixed-feed through a first part of the reaction chamber, and a means for flowing a second mixed-feed through an annular portion of a second part of the reaction chamber, the second part being a tube-in-tube in fluid communication with the first part. The burner(s) generates a flow of a flue gas having a sensible heat from the combustion chamber to the convection chamber. The flow of the flue gas in the convection chamber is counter-currently with the flow of the second mixed-feed.
