摘要: Processes and apparatuses for separating chlorides from a butane product stream by removing chlorides from a portion of said feed stream in a rectification section of the separation zone. The rectification section may be in a rectification column which may be combined with a stripper column. Alternatively, a wall may be used to provide the rectification section in a fractionation column. The processes and apparatuses can be used in both new designs and revamped designs.

摘要: Methods and systems for treating an olefin-containing stream are disclosed. The disclosed methods and systems are particularly suitable for treating an off-gas stream in a refining or petrochemical process, such as from a fluid catalytic cracker (FCC), coker, steam cracker, and the like. The stream is treated in an absorber column to reject lighter stream components and to absorb ethylene and/or propylene into a solvent. The solvent is typically isobutane. The enriched solvent stream from the absorber column is fed to an alkylation reactor, which reacts the dissolved olefin with the isobutane solvent to produce an alkylate product.

摘要: A process for the separation of a natural gas stream is provided. The process includes receiving an effluent gas flow from a first fractionator operating at a first pressure, splitting the effluent gas flow into a first stream and a second stream, and passing the first stream through a heat exchanger thereby causing a phase change of at least a portion of the first stream from a gaseous state to a liquid state. The process includes inserting the first stream into an upper portion of a second fractionator operating at a second pressure. The second pressure is lower than the first pressure. The process includes inserting the second stream into a lower portion of the second fractionator, and diverting liquids from a lower portion of the second fractionator to the first fractionator.

摘要: The present disclosure relates generally to processes and systems for producing liquid transportation fuels by converting a feed stream that comprises both isopentane and n-pentane, and optionally, some C6+ hydrocarbons. Isopentane and smaller hydrocarbons are separated to form a first fraction while n-pentane and larger components of the feed stock form a second fraction. Each fraction is then catalytically-activated in a separate reaction zone with a separate catalyst, where the conditions maintained in each zone maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. In certain embodiments, the first fraction is activated at a lower temperature than the second fraction. Certain embodiments additionally comprise mixing at least a portion of the two effluents and contacting with either an oligomerization catalyst or alkylation catalyst to provide enhanced yields of upgraded hydrocarbon products that are suitable for use as a blend component of liquid transportation fuels or other value-added chemical products.

摘要: Methods and systems for the dehydrogenation of hydrocarbons include a direct contact condenser to remove compounds from an offgas process stream. The reduction of compounds can decrease duty on the offgas compressor by removing steam and aromatics from the offgas. The dehydrogenation reaction system can be applicable for reactions such as the dehydrogenation of ethylbenzene to produce styrene, the dehydrogenation of isoamiline to produce isoprene, or the dehydrogenation of n-pentene to produce piperylene.
