The present disclosure relates to the integration of systems and methods associated with steam cracking, oligomerization reactions, hydrogenation reactions, and aromatization reactions for the production of benzene via the hydrogenation of oligomers produced from ethylene. In some aspects, the disclosed systems and methods utilize one or more of an oligomerization process, a hydrotreating process, and an aromatization process for producing a benzene comprising effluent. In further aspects, the systems and methods disclosed herein utilize one or more selective oligomerization catalyst systems.

Flexible benzene production via selective-higher-olefin oligomerization of ethylene

Processes for using pyrolysis gas as a feedstock or a co-feedstock for making a variety of chemicals, for example, circular ethylene, circular ethylene polymers and copolymers, and other circular products. In these processes, pyrolysis reactor conditions can be selected to increase or optimized the production of pyrolysis gas over pyrolysis oil, and the pyrolysis gas which is usually used as fuel or flared can be fed downstream of the steam cracker furnace for economic use to form circular chemicals. Operating parameters of the pyrolysis unit may be adjusted to increase or decrease the proportion of pyrolysis gas relative to pyrolysis liquid as a function of their relative economic values.

Pyrolysis of plastic waste to produce light gaseous hydrocarbons and integration with an ethylene cracker

A system for processing plastic waste may include a feed line, a feed fractionator, a hydrotreater, a catalytic reforming unit, a heavy oil cracker, and a steam cracker. A pyrolyzed plastics feed is separated into light, medium, and heavy hydrocarbon streams. The hydrotreater removes sulfur, and the catalytic reforming unit produces a circular aromatic-rich stream. The heavy oil cracker generates cracked streams. The steam cracker produces a circular olefin stream from a cracked stream. A system for processing plastic waste may include the feed line, the feed fractionator, the hydrotreater, a medium hydrocarbon fractionator, the catalytic reforming unit, a full-range reforming unit, the heavy oil cracker, and the steam cracker. The medium hydrocarbon fractionator produces two hydrocarbon streams. The full-range naphtha reforming unit produces a second circular aromatic-rich stream.

Systems and processes for processing pyrolysis oil

This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based, fossil fuel-based, or bio-based feedstock. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways. The use of a mass balance approach which attributes the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit has been developed, which permits ISCC certification agency approval.

Circular chemicals or polymers from pyrolyzed plastic waste and the use of mass balance accounting to allow for crediting the resultant products as circular

This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based or fossil fuel co-feed, or as a feedstock in the absence of a petroleum-based or fossil fuel co-feed. A mass balance accounting approach is employed to attribute the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit, which permits assigning circular product credit to product streams. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways.

A process for operating a reforming system by operating a reforming section containing a plurality of reactors, wherein each of the plurality of reactors containing a reforming catalyst capable of catalyzing the conversion of at least a portion of the hydrocarbons in a treated hydrocarbon stream into a reactor effluent comprising aromatic hydrocarbons, and operating a sulfur guard bed (SGB) to remove sulfur and sulfur-containing hydrocarbons from a hydrocarbon feed to provide the treated hydrocarbon stream, where the SGB contains at least a layer of a SGB catalyst comprising the same catalyst as the reforming catalyst, and where each reactor of the plurality of reactors within the reforming section may be operated at a higher operating temperature than an operating temperature of the SGB. A system for carrying out the process is also provided.

Use of Aromax&#xae; catalyst in sulfur converter absorber and advantages related thereto

A method of monitoring catalytic performance of a catalyst used in a reforming process, comprising a) collecting gaseous component data from the reforming process; b) calculating a gaseous component ratio from the gaseous component data; and c) utilizing the gaseous component ratio to estimate an amount of catalytic activity remaining in the catalyst used in the reforming process, a number of days on stream remaining for the catalyst used in the reforming process, or both.

A communication network that combines radios using RF communication and devices that communicate over the public switched telephone network and/or a cellular network so that the various devices can communicate across a single system with the radios being callable from any other device connected to the system. The system combines Radio over Internet Protocol communication with Voice over Internet Protocol communication into a single integrated architecture that allows seamless communication by all communication devices connected to the system.

Integrated VoIP and RoIP communication network

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.
