Abstract: A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A common depropanizer fractionates propane feed and pyrolysis reactor effluent to provide a C3 stream. A dividing wall may be used in the column to prevent cross contamination by the pyrolysis effluent with the propane dehydrogenation feed.

Abstract: An apparatus and process heat a process stream taken from a separator vessel by heat exchange with a hydroprocessed effluent stream and return the heated process stream to the separator vessel. We have found the significant heater duty reduction is provided particularly for a hydroprocessing unit. A spiral tube heat exchange can achieve heating of an already hot process stream by heat exchange with a hot effluent stream.

Abstract: A process for recovering heat from the separation of hydrocarbons. The overhead vapor stream from a fractionation column is passed to a two stage heat pump compressor. The first stage of compression is used to reboil the fractionation column. The second stage is compressed and cooled passed to a separation zone. The liquid in the separation zone may be passed back to the fractionation column as secondary reflux, and/or recovered as liquid product. Heat may also be removed from the second stage. A suction drum on the first stage may be used to protect the heat pump compressor from any droplets in the overhead stream.

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: A co-generation process for a regenerator in an FCC system having a reactor and a regenerator includes the steps of introducing flue gas from the regenerator into a heating unit at a first location of the heating unit, and introducing an oxygen/fuel gas mixture into the heating unit at a second location of the heating unit apart from the first location, and combusting the oxygen/fuel gas mixture in the heating unit at the second location to form a hot combustion gas. The process further includes the steps of combining the hot combustion gas and the flue gas at a third location of the heating unit apart from the first location to produce heated flue gas, heating water and/or steam with the heated flue gas to produce a heated steam, and introducing the heated steam into a turbine to extract energy from the heated steam.

Abstract: One exemplary embodiment can be a process for treating a hydroprocessing fraction. The process can include obtaining a bottom stream from a fractionation zone, and passing at least a portion of the bottom stream to a film generating evaporator zone for separating a first stream containing less heavy polynuclear aromatic compounds than a second stream.

Abstract: Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent to form a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is compressed, partially condensed and cooled to form a partially condensed, compressed net gas phase stream. The partially condensed, compressed net gas phase stream is separated to form an intermediate gas phase stream. The intermediate gas phase stream and the liquid phase hydrocarbon stream are combined to form a two-phase combined stream. The two-phase combined stream is cooled and separated to form an H2-rich stream and a cooled second intermediate liquid phase hydrocarbon stream that is enriched with C3/C4 hydrocarbons and further comprises C5+ hydrocarbons.

Abstract: Methods and apparatuses are provided for hydrotreating hydrocarbons. A method includes heating a start-up oil in a stripper liquid fraction heat exchanger during a start-up period, and heating a reactor with the start-up oil. The start-up oil is discharged from the reactor when the start-up period ends, and a standard operating period begins after the start-up period. A reactor effluent is produced by introducing a hydrocarbon stream into the reactor during the standard operating period, where hydrogen sulfide is produced from an organic sulfur compound in the hydrocarbon stream. Steam is produced in the stripper liquid fraction heat exchanger during the standard operating period.
