    Abstract: Systems and processes for heat recovery associated with the separation of hydrocarbon components. Two compressors are used to compress a portion of an overhead vapor stream from a fractionation column. A pressure of the liquid portion of the compressed overhead is reduced and used to recover heat from an overhead of another separation zone having a fractionation column. Once the heat has been recovered the stream is recompressed. The recovered heat may be removed from the recompressed stream in a reboiler of another fractionation column. The fractionation columns may comprise a deethanizer stripper, propane-propylene splitter, and a depropanizer column.

    Abstract: An apparatus and process is disclosed for the cooling of a reactor effluent gas stream. The apparatus includes a contact cooling system with a discharge drum providing a second wash zone. Each wash zone has a packed bed, or other type of mechanical system for contacting the gas stream with the cooling liquid. The liquid in the first stage will remove heavy components, allowing for a cleaner second stage that can be reduced in size.
