Abstract: A process for recovering catalyst from a fluidized catalytic reactor effluent is disclosed comprising reacting a reactant stream by contact with a stream of fluidized catalyst to provide a vaporous reactor effluent stream comprising catalyst and products. The vaporous reactor effluent stream is contacted with a liquid coolant stream to cool it and transfer the catalyst into the liquid coolant stream. A catalyst lean vaporous reactor effluent stream is separated from a catalyst rich liquid coolant stream. A return catalyst stream is separated from the catalyst rich liquid coolant stream to provide a catalyst lean liquid coolant stream, and the return catalyst stream is transported back to said reacting step.

Abstract: A process for pyrolysis of a mixed plastic stream that contains polyvinyl chloride (PVC) is provided in which the chloride from PVC is removed from an initial melting reactor that heats the mixed plastic stream to a sufficient temperature to produce HCl but at a low enough temperature to avoid production of organochlorides. Chloride is primarily removed in a vapor stream from the initial melting reactor, while additional chloride removal may be removed downstream from the melting reactor by the use of sorbent addition to the pyrolysis reactor and by subsequent adsorbent beds.

Abstract: A process and apparatus cool and remove catalyst from a hot vaporous reactor effluent stream by feeding the hot vaporous reactor effluent stream comprising catalyst and a first quench liquid stream to a first quench chamber. The hot vaporous reactor effluent stream is directly contacted with the first quench liquid stream to cool the hot reactor effluent stream and wash catalyst therefrom into the first quench liquid stream. The first quench liquid stream and the vaporous reactor effluent stream are passed together through a bed while disengaging catalyst from the vaporous reactor effluent stream and transferring catalyst into the first quench liquid stream.

Abstract: We have discovered that addition of water to a mixture of oxygenates increases their volatility relative to methanol. A process and apparatus are disclosed for separating methanol from other oxygenates. Water is separated from a stream comprising water, methanol and at least one other oxygenate to provide a water rich stream and a methanol and oxygenate rich stream. The methanol and oxygenate rich stream and water are fed to a column to provide an oxygenate rich stream and a methanol and water extract stream. The methanol and water can then be readily separated from each other.

Abstract: Embodiments of methods and apparatuses for recovery of ethylene from FCC absorber off-gas comprising a heavy cut comprising ethylene, ethane and heavier hydrocarbons and a light cut comprising hydrogen, nitrogen and methane. An exemplary method includes passing the FCC absorber off-gas to an adsorption zone containing an adsorbent selective for the adsorption of the light cut, the adsorption zone adsorbing at least a portion of the light cut and recovering an adsorption zone effluent stream comprising the heavy cut. The adsorption zone effluent is passed to a demethanizer column to provide an overhead stream comprising hydrogen, nitrogen, methane, ethylene and ethane and a net bottoms stream comprising ethylene, ethane and the heavier hydrocarbons.

Abstract: Processes for producing a propylene stream having at least 95% propylene and a reduced level of dienes. A selective hydrogenation zone converts dienes into olefins in a stream having at least C3 and C4 olefins from a feed stream including butene and C4 dienes. The selective hydrogenation zone may be disposed between a demethanizer and a deethanzier or it may be disposed downstream of both the demethanizer and the deethanizer. A C3 splitter and an acetylene conversion zone may be utilized.

Abstract: A process is presented for removing the fouling problems associated with the product recovery in a methanol to olefins conversion process. The process includes passing the quenched MTO process stream to a product separator, wherein an intermediate stream is generated and includes water and heavier hydrocarbons. The intermediate stream is processed to remove the buildup of heavier hydrocarbons.
