    Abstract: A process for a catalytic reforming system, the process comprising controlling an amount of aromatic hydrocarbon fed to a sulfur removal system in the catalytic reforming system such that a temperature of a reduced sulfur stream flowing from the sulfur removal system is higher than a temperature of a stream which is fed to the sulfur removal system, due to a heat of reaction generated in the sulfur removal system by converting at least a portion of the aromatic hydrocarbon to aliphatic hydrocarbons. A process for a catalytic reforming system, the process comprising feeding an effective amount of aromatic hydrocarbons to a sulfur removal system of the catalytic reforming system such that a heat duty of a first furnace of a plurality of reactor-furnace pairs connected in series in the catalytic reforming system is reduced relative to operation of the sulfur removal system without the effective amount of aromatic hydrocarbons.

    Abstract: A method of processing one or more streams in a benzene production system comprising receiving a reactor effluent stream comprising benzene from an aromatization reactor system; introducing reactor effluent stream into a first separator to produce first gas stream and first liquid stream; splitting the first gas stream into first portion and second portion of first gas stream; introducing first portion of first gas stream into a first compressor to produce first compressed gas stream; introducing first compressed gas stream into a second separator to produce recycle gas stream comprising hydrogen and second liquid stream; recycling recycle gas stream to aromatization reactor system; introducing second portion of first gas stream into a second compressor to produce second compressed gas stream; introducing second compressed gas stream into a third separator to produce gas product stream comprising hydrogen and third liquid stream; and optionally recycling gas product stream to aromatization reactor system.

    Abstract: A system of reforming reactors comprises a plurality of reactors coupled by flow lines, a feed header coupled to the plurality of reactors by a plurality of feed lines, an effluent header coupled to the plurality of reactors by a plurality of effluent lines, and a plurality of valves disposed in the flow lines, the feed lines, and the effluent lines. Each reactor comprises a reforming catalyst, and the plurality of valves are capable of being dynamically operated to create a first serial flow path through the plurality of reactors. The plurality of valves is further configured to dynamically reconnect the plurality of reactors to create a second serial flow path through the plurality of reactors. A first reactor of the plurality of reactors is adjacent to a second reactor of the plurality of reactors in the first serial flow path, and the first reactor is not adjacent to the second reactor in the second serial flow path.

    Abstract translation: 重整反应器的系统包括多个通过流动管线联接的反应器，通过多个进料管线连接到多个反应器的进料头，通过多条流出物管连接到多个反应器的流出物集管，以及多个反应器 设置在流动管线中的阀，进料管线和流出物管线。 每个反应器包括重整催化剂，并且多个阀能够被动态地操作以产生通过多个反应器的第一串联流动路径。 多个阀还被配置为动态地重新连接多个反应器以产生穿过多个反应器的第二串联流动路径。 多个反应器的第一反应器与第一串联流路中的多个反应器的第二反应器相邻，并且第一反应器不与第二串联流路中的第二反应器相邻。
