    摘要: Fractionation systems utilizing a rectifying column with a stripping column are described. The liquid from the rectifying column bottoms is sent to the first tray of the stripping column, while the overhead stream from the stripping column is sent to the bottom of the rectifying column. Processes for separating feed streams are also described.

    摘要: A process and apparatus integrate a deethanizer column with a cryogenic heat exchanger by reboiling the deethanizer column with a refrigerant stream and/or cooling a deethanizer overhead line in the cryogenic heat exchanger. A single stage separator and a single deethanizer column may be used to obtain high purity hydrogen in the net gas stream and an ethane rich off-gas stream, whereas conventionally a dual stage separator and two deethanizer columns were necessary for equivalent purity, respectively.

    摘要: 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.

    摘要: 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.
