Systems and methods for producing light olefins and BTX are disclosed. A feed stream comprising mixed Cparaffins is first separated into a first stream comprising primarily isobutane, and a second stream comprising primarily n-butane. The first stream is processed in a catalytic cracking unit and the second stream is processed in a steam cracking unit. The resulting streams from the catalytic cracking unit and the steam cracking unit are separated to form product streams including an ethylene stream, a propylene stream, and a BTX stream.

Process for producing light olefins (ethylene + propylene) and BTX using a mixed paraffinic Cfeed

The present invention relates to a method for preparing linear alpha-olefins by oligomerizing of ethylene in the presence of a first organic solvent and a homogenous catalyst in a reactor, characterized in that the reactor overhead is cooled by means of a refrigerant.

Method for preparing linear alpha-olefins with improved heat removal

The present invention relates to a method for the deactivation of an organometallic catalyst in the product stream from an oligomerization reactor for the production of linear alpha-olefin, characterized in that the catalyst-containing product stream of the reactor is subjected to a temperature of at least 160&#xb0; C. in a heating device. A reactor system for the method of the invention is also disclosed.

Method for deactivation of an organometallic catalyst and reactor system therefor

The present invention relates to a method for oligomerization or polymerization of ethylene and/or alpha-olefins utilizing reactor equipment and other equipment wherein starting material comprising monomer(s), catalyst, cocatalyst and solvent is transferred to the reactor equipment via first piping, and product material comprising oligomer and/or polymer, non-reacted monomer(s), catalyst, cocatalyst and solvent is discharged from the reactor equipment via second piping, characterized in that the first piping, second piping, reactor equipment and/or other equipment are flushed with a product fraction obtained by said or a respective previous method prior to and/or after that oligomerization or polymerization method.

Method for oligomerization and/or polymerization of ethylene with flushing of equipment and piping

The present invention relates to a bubble column reactor comprising a column reactor having a sparger plate dividing the column reactor into a top reaction compartment and a bottom compartment, characterized in that an inlet and outlet line for introducing and disposing a flushing medium are connected to the bottom compartment; and an operation method thereof.

Method for operating bubble column reactor for the oligomerization of ethylene

The present invention relates to a method for processing high molecular weight oligomer waste products formed during the production of linear alpha-olefins by oligomerization of ethylene in a reactor in the presence of a solvent and a catalyst, characterized in that the high molecular weight oligomers are separated in a separation unit from a product stream of the reactor comprising the solvent, the catalyst, linear alpha-olefins and high molecular weight oligomers having a solidification temperature in the range of about 60-100&#xb0; C., then diluted with a dilution medium and heated to about 130&#xb0; C. to about 200&#xb0; C., the diluted high molecular weight oligomers are then transferred to a disposal device, wherein at least some of the dilution medium may be recovered and recycled for addition to the dilution medium.

Method for the preparation of linear alpha-olefins and reactor system therefore with improved disposal of high molecular weight oligomers
