    Abstract: This invention relates to the integration of an ammonia production process with a fermentation process to produce products such as alcohols and/or acids in addition to ammonia. In a specific embodiment, a natural gas stream comprising methane is passed to a reforming zone to produce a substrate comprising CO and H2. The substrate is next passed to a bioreactor containing a culture of one or more microorganisms and fermenting the culture to produce one or more fermentation products comprising alcohols and/or acids and an exhaust stream comprising CO2, and H2. The exhaust stream can then be passed to a separation zone to remove at least a portion of the CO2 and produce a purified exhaust stream comprising H2 which is then passed to an ammonia production zone and is used to produce ammonia.

    Abstract: One exemplary embodiment can be a system for separating a plurality of naphtha components. The system can include a column, an overhead condenser, and a side condenser. Generally, the column includes a dividing imperforate wall with one surface facing a feed and another surface facing at least one side stream. Typically, the wall extends a significant portion of the column height to divide the portion into at least two substantially vertical, parallel contacting sections. Typically, the overhead condenser receives an overhead stream including a light naphtha from the column. Usually, a side condenser receives a process stream from the column and returns the stream to the column to facilitate separation. A cooling stream may pass through the overhead condenser and then the side condenser.

    Abstract: Processing schemes and arrangements are provided for obtaining ethylene and ethane via the catalytic cracking of a heavy hydrocarbon feedstock and converting the ethylene into ethyl benzene without separating the ethane from the feed stream. The disclosed processing schemes and arrangements advantageously eliminate any separation of ethylene from ethane produced by a FCC process prior to using the combined ethylene/ethane stream as a feed for an ethyl benzene process. Further, heat from the alkylation reactor is used for one of the strippers of the FCC process and at least one bottoms stream from alkylation process is used as an absorption solvent in the FCC process.

    Abstract: Processing schemes and arrangements are provided for obtaining propylene and propane via the catalytic cracking of a heavy hydrocarbon feedstock and converting the propylene into cumene without separating the propane from the propane/propylene feed stream. The disclosed processing schemes and arrangements advantageously eliminate any separation of propylene from propane produced by a FCC process prior to using the combined propane/propane stream as a feed for a cumene alkylation process. A bottoms stream from the cumene column of the cumene alkylation process can be used and an absorption solvent in the FCC process thereby eliminating the need for a transalkylation reactor and a DIPB/TIPB column.

    Abstract: This ethylbenzene process involves contacting, in an alkylation zone, a first benzene recycle stream and an ethylene feed stream with an alkylation catalyst to form ethylbenzene. In a transalkylation zone, a polyethylbenzene recycle stream and a second benzene recycle stream are contacted with a transalkylation catalyst to form additional ethylbenzene. The effluents are passed into a dividing wall distillation column where a benzene overhead and a benzene side draw are removed and recycled. An ethylbenzene stream product stream is also removed. The remainder, largely polyethylbenzene and tar, is passed to a polyethylbenzene column for separation. The separated polyethylbenzene is recycled to the transalkylation reactor.
