摘要： A novel cyclone is disclosed that is effective for separating, from a contaminated gas stream, solid particulates having diameters as low as 4-5 microns. When multiple cyclones of the present invention are affixed between upper and lower tube sheets in a separator device, fine particle removal is possible to the extent required 1) by stringent regulations governing particulate emissions into the atmosphere, or 2) to prevent damage to turbine blades in downstream power recovery equipment. The cyclones are especially relevant to the problem of removing catalyst fines from refinery effluents, most notably fluid catalytic cracking (FCC) regenerator flue gas. The cyclone separation efficiency is enhanced through the use of 1) a uni-directional flow of gas from the contaminated gas inlet to the clean gas outlet and 2) discharge openings on the surface of the cyclone body that allow ejection of solid particulates.

摘要： A third stage separator vessel includes a diffuser to promote uniform flow among an array of separation cyclones in the vessel. The vessel has an inlet to receive a gas stream containing solid particles, and the diffuser is mounted at the inlet so that at least some of the stream passes through the diffuser. In an embodiment, a gap between the diffuser and the inlet causes some of the gas stream to flow over an outer surface of the diffuser. The diffuser preferably includes a perforated plate mounted across a wide end of a frustoconical portion. The plate has a plurality of openings through which the flow passes. The openings in the plate have various sizes and positions to direct a greater amount of flow through radially outward portions of the plate than from a central portion of the plate.

摘要： A process and apparatus is presented for the improved selectivity of oxygenate conversion to olefins. The process includes passing a process stream through a two stage reactor, wherein the process stream is separated from the catalyst in the first stage before passing the process stream to the second stage. The catalyst is continuously passed through the two stages, and cycles through a regeneration unit to control the carbon content on the catalyst.

摘要： Processes and apparatuses for regenerating catalyst particles are provided. The processes include introducing spent catalyst particles to a burn zone in a continuous catalyst regenerator. When introduced, the catalyst particles, which contain a platinum group metal, carry coke deposits. In the process, a combustion gas at a temperature of at least 490° C. with an oxygen content of at least 0.5 mol % is fed to the burn zone. There, the coke deposits on the catalyst particles are combusted with the combustion gas. The catalyst particles are passed from the burn zone to a halogenation zone in the continuous catalyst regenerator and the catalyst particles are oxyhalogenated to redisperse the platinum group metal to form regenerated catalyst particles.

摘要： The invention comprises an absorption heat pump to supply energy to a distillation process or an outside process. The streams used to effect the absorption heat pump are to be combined in any case as a feedstream to a conversion process, and energy thus is conserved by avoiding the necessity of reseparating the streams.

摘要： A distillation column is disclosed. The column includes a plurality of rectification zones and corresponding stripping zones. Each rectification zone is linked to a heat pump or a stage of a heat pump. Overhead material from the top rectification zone is compressed and used to heat bottoms liquid from the bottom stripping zone. Similarly, overhead material from a lower rectification zone is compressed and used to heat liquid taken from the uppermost or top stripping zone. Optionally, overhead material from a middle rectification zone is compressed and used to heat liquid from a middle stripping zone. A single multiple stage heat pump compressor may be utilized as opposed to a plurality of heat pumps. Because the heat exchanger from each rectification-stripping zone pair has a lower duty, economical stab-in heat exchangers may be utilized.

摘要： A new reactor design is presented for a counter-current flowing reactor. The reactor has a catalyst flowing down through the reactor, and over baffles. Gas is admitted under the baffles and flows up through the solid catalyst bed. The design includes slotted plates that extend from the bottom of the baffle in the reactor to a position near the catalyst outlet. The gas flows through the slotted plates and is directed up through the catalyst bed, while directing the flowing catalyst to the catalyst outlet ports.
