摘要： The present invention relates to a process and apparatus for the production of light olefins comprising olefins having from 2 to 3 carbon atoms per molecule from a feedstock containing heavier olefins. An intermediate cut from a fractionation column is used as olefinic feed to an olefin cracking process preferably after undergoing selective hydrogenation of diolefins. In one embodiment, a liquid side draw from a fractionation column is selectively hydrogenated and then returned to the fractionation column from which a vapor side draw containing olefins is cracked in the olefin cracking reactor.

摘要： A combination of an etherification process and a process for the isomerization of linear alkenes to isoalkenes uses a separation zone that receives an effluent stream from the etherification reaction zone and separates it into a high boiling stream, a low boiling stream and an intermediate boiling stream in order to reduce the mass flow of reactants through the isomerization and etherification reaction zones. The separation zone includes at least one distillation column. The distillation column can provide a distillation function only, or can also provide a reactive distillation zone. The intermediate boiling stream leaves a two column separation zone as a bottoms stream from a second column or in a single column separation zone as a sidecut which in the case of reactive distillation is taken from the point above a bed of catalyst within the column. Taking the sidecut stream substantially eliminates the circulation of isoalkane hydrocarbons through the etherification and isomerization zone and maintains normal alkanes at an acceptable equilibrium level. The effluent from the isomerization zone may enter the first in a series of etherification zones or may enter a second etherification zone having higher capacity.

摘要： A processing scheme and arrangement for enhanced olefin production involves recovering thermal energy from a reactor effluent stream resulting from the dehydrogenation of a dehydrogenatable hydrocarbon. The process involves contacting the reactor effluent stream with a circulating fluid stream in a first contact cooling zone to produce a product stream and to form a heated circulating fluid stream. Thermal energy is recovered from the heated circulating fluid stream via indirect heat exchange with a first process stream in a first heat exchange zone to form a cooled circulating fluid stream. The cooled circulating fluid stream can be subsequently cooled and at least a first portion thereof returned to the first contact cooling zone.

摘要： A process for the production of propylene from a propane rich hydrocarbon source is presented. The process converts a propane rich stream and uses less equipment and energy for the separation and production of propylene. The process uses a non-noble metal catalyst and utilizes a continuous reactor-regeneration system to keep the process on line for longer periods between maintenance.

摘要： A process for regenerating solid treating particles contained in at least two vessels of a swing bed regeneration operation where the effluent of the regeneration operation is maintained regeneration fluid-free and at a substantially constant flowrate has been developed. The swing bed regeneration operation involves at least two vessels, one of which is on-line treating process fluid, and the other is off-line for regeneration. At least a portion of the process fluid effluent from the vessel on-line is conducted to a displacement surge drum. The flowrate of the process fluid effluent from the displacement surge drum is controlled so that downstream units receive a substantially constant flowrate. A portion of the process fluid effluent from the displacement surge drum or a portion of the process fluid effluent from the vessel on-line is periodically used to displace regeneration fluid from the vessel off-line, and during the displacement, the flowrate of effluent from the displacement surge drum is increased to provide additional flow to the vessel off-line without having to reduce the flow to downstream units. In a specific embodiment, both process fluid and regeneration fluid are conducted to the displacement surge drum. The process fluid is used as described above. The regeneration fluid is used to displace process fluid from the vessel that is off-line prior to regeneration of the treating particles. In another specific embodiment, the treating particles are rinsed prior to regeneration to desorb and recycle any adsorbed reactant.
