Abstract: An apparatus for hydrocarbon conversion, the apparatus including a reactor and a reactor insert secured and disposed within an interior cavity of the reactor, is described. The reactor is configured to permit addition of a feed stream comprising a hydrocarbon at an upstream end of the reactor and to permit discharge of a product stream at a downstream end of the reactor. The reactor insert is configured to provide heat to the interior cavity to promote conversion of hydrocarbons as the feed stream moves from the upstream end of the reactor to the downstream end of the reactor. The products of the conversion reaction are discharged at the downstream end as part of the product stream. A method for hydrocarbon conversion using the apparatus is also described.

Abstract: Disclosed herein are polymerization processes where recycled polymeric material is fed to polymerization process to produce a blend of virgin polymer with recycled polymeric content.

Abstract: An apparatus for hydrocarbon cracking includes a reactor and a heating component. The reactor has an interior cavity configured to receive a feed stream. The feed stream includes a hydrocarbon. The heating component surrounds the reactor. The heating component is configured to provide heat to an external surface of the reactor to crack the hydrocarbon and produce a product stream. The product stream includes a C2-C4 alkene, syngas, or a combination thereof. The reactor is configured to discharge the product stream. The heating component can include an electrical resistor, a combustion chamber, or both.

Abstract: A burner and associated methods are disclosed. The burner comprises a housing and a heat shield. The housing comprises an inlet for receiving gas, one or more outlets for expelling gas, and walls forming a gas cavity for directing the gas from the inlet to the outlet. The heat shield comprises a shield layer configured to cover at least a portion of at least one of the walls to thermally insulate the at least one of the walls from heat outside the gas cavity.

Abstract: The present disclosure seeks to provide a metallic burner tile for use in industrial processes such as cracking. The tile is substantially metallic (e.g. more than 80%) with the balance being ceramic coating on surfaces exposed to high temperature. The tile is lighter and more durable than the current ceramic burners.

Abstract: Provided herein are components for a fluid network, specifically a U bend structure connected to at least two pipes which is modified for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The U bend structure is so designed to have a specific ARQ between 1.0 to 1.02 for 5% of the flow passage from the inlet and from the outlet, and an ARQ from 1.02 to 1.15 over the remaining 90% of the flow passage through an Rb/D ratio being greater than 1 and less than 4.

Abstract: The present invention provides a transfer line exchanger which is optimized for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The transfer line exchanger is designed by computer modeling a transfer line exchanger in which the cross section of flow path is substantially circular and modeling the operation of the transfer line under industrial conditions to validate the model design and its operation. Then iteratively the model design is deformed and the operation of the deformed part is modeled and compared to values obtained with other deformed models until the value of the objective function is optimized (e.g. at an extreme) or the change in the objective function is approaching zero.

Abstract: This invention relates to a self cleaning reactor and to a process for the oligomerization of ethylene that employs a self-cleaning reactor. The reactor includes a mass of inert, particulate cleaning bodies that are entrained by the liquid in the reactor and scour the internal surfaces of the reactor during normal operation. This scouring action reduces the level of fouling on the reactor surfaces. Foulant material (polyethylene) is removed from the process on a continuous basis but the cleaning bodies remain within the reactor.

Abstract: Oxidative dehydrogenation is an alternative to the energy extensive steam cracking process presently used for the production of olefins from paraffins. Various embodiments of an oxidative dehydrogenation chemical complex designed to allow removal of sulfur containing contaminants that collect in the gas mixer unit and in the feed lines leading to the ODH reactor are disclosed herein.

Abstract: This disclosure relates to a method and an apparatus for the delivery of a multi-component olefin polymerization catalyst to a polymerization reactor. The components soluble in a first solvent are delivered under pressure along with that solvent in a first delivery conduit. The components that are insoluble in the first solvent but are soluble in a second solvent are delivered under pressure in a second delivery conduit which is arranged coaxially with and disposed within the first conduit, such that the inner conduit and outer conduit terminate at a common catalyst component mixing conduit which extends into the polymerization reactor and in which the catalyst components mix to form an active polymerization catalyst.

Abstract: If a cracked gas heat exchanger becomes damaged water may enter the transfer line causing it to rupture. This may be avoided using a heat exchanger having heat pipes to conduct heat from the cracked gas to a cooling device, typically a water cooler to generate steam. The latter (cooling device) is physical separated from the hot cracked gas stream. The heat pipes may be modified at the hot or cold end with fins, ribs, protuberances, pins and the like.

Abstract: A method for preventing or removing water soluble fouling located downstream of an oxidative dehydrogenation (ODH) reactor is described. The method employs the introduction of water upstream of fouling locations, either continuously or intermittently, which acts to solubilize and carry away fouling material. The method has the advantage of being applicable for use while an ODH process is ongoing, circumventing the need for a costly shutdown.
