Abstract: Processes and systems for steam cracking hydrocarbon feeds. The process can include introducing a first hydrocarbon feed into radiant coil(s) disposed within a first segment of a firebox to produce a first steam cracker effluent having a first coil outlet temperature. A second hydrocarbon feed can be introduced into radiant coil(s) disposed within a second segment of the firebox to produce a second steam cracker effluent having a second coil outlet temperature. The first and second segments can each include one or more burners providing heat thereto. The burner(s) in each segment can be operated at substantially the same firing rate such that an amount of heat produced by each burner can be substantially the same. A feed rate of the first hydrocarbon feed can be controlled based, at least in part, on a composition of the first hydrocarbon feed and the first coil outlet temperature.

Abstract: Processes and systems for quenching an effluent. In certain embodiments, the process can include contacting a pyrolysis effluent and a first quench medium to produce a first quenched effluent. A bottoms stream that can include tar and an overhead stream that can include ethylene and propylene can be obtained from the first quenched effluent. The first quench medium can include a first portion of the bottoms stream that can include a first portion of the tar. In certain embodiments, the process can also include hydroprocessing a second portion of the bottoms stream that can include a second portion of the tar to produce a hydroprocessed product. A hydroprocessed bottoms stream can be obtained from the hydroprocessed product. In certain embodiments, the process can also include contacting at least a portion of the hydroprocessed bottoms stream and the first portion of the bottoms stream to produce the first quench medium.

Abstract: The present disclosure relates to processes, methods, systems, and apparatus for steam cracking hydrocarbon in a pyrolysis furnace having a convection zone and a radiant zone. The convection zone includes three heat exchangers in series with a serpentine arrangement. A fluid source is disposed each heat exchanger to provide steam into the heat exchangers. The present disclosure further relates to a process of adjusting the stream flow rate for each fluid source to control operating conditions such as flue gas temperature, stack temperatures, and temperatures of other components of the furnace.

Abstract: The invention relates to dispersions of porous solids in liquids selected from deep eutectic solvents, liquid oligomers, bulky liquids, liquid polymers, silicone oils, halogenated oils, paraffin oils or triglyceride oils, as well as to their methods of preparation. In embodiments of the invention, the porous solids are metal organic framework materials (MOFs), zeolites, covalent organic frameworks (COFs), porous inorganic materials, Mobil Compositions of Matter (MCMs) or a porous carbon. The invention also relates to the use of porous materials to form dispersions, and to assemblages of such dispersions with a gas or gases. The dispersions can exhibit high gas capacities and selectivities.

Abstract: Index values are periodically incremented at a central or primary video production control system and a video production control system node. Messages that include or otherwise indicate current index values generated by the primary video production control system are transmitted to the video production control system node, and the node reflects the messages back to the primary video production control system. The primary video production control system determines a round-trip message time, associated with the video production control system node, based on the transmitted messages and reflections of the messages received from the node. A further message that includes or otherwise indicates an instruction for execution of a task at a target execution time, is transmitted by the primary video production control system to the node at a time, in advance of the target execution time, that is based on the round-trip message time.

Abstract: The present invention provides a method for catalytic oxidation of alkanes, where the catalyst comprises a photoactive material that is activated when the catalyst is irradiated with UV light. In particular, the method is for the catalytic oxidation of a C1-C5 alkane using an oxidation catalyst comprising a photoactive material, said method comprising the steps of a) activating the photoactive material by irradiating the catalyst with UV light and b) contacting the activated catalyst with a gaseous feedstream comprising an amount of C1-C5 alkane at a temperature of from 150° C. to 600° C.

Abstract: A device to provide support to a support strand when a small cell is mounted thereto to limit amount of droop that occurs on the support strand when the small cell is mounted thereto. The strand support device is mounted to a telephone pole (via a suspension clamp that is mounted to the pole to secure the support strand thereto) and includes a mounting rod and a support rod that extend outward from the pole. The distance the device extends from the pole is based on the distance from the pole that the small cell is located. The device connects to the support strand in proximity to where the small cell is mounted. Connecting to the support strand rather than the small cell ensures that no damage is done to the small cell. The device may be adjustable so that it can be utilized in different situations.

Abstract: According to one aspect of the invention, there is provided the use of an organic ionic liquid in a zeolite-catalysed process, for example an acylation, alkylation, isomerisation or hydrocracking process in which zeolites act as catalysts or catalyst precursors, especially Friedel-Crafts alkylation and acylation procedures.

Abstract: An air outlet system of a sphere and socket type. The air outlet system includes a housing, a hollow sphere rotatably mounted therein, and a bearing therebetween; and pluralities of openings in respective predetermined shapes formed in oppositely disposed portions of the hollow sphere for dispersing air supplied thereto from a remote source in respective diffused or straight paths, depending upon the rotational position of the hollow sphere in the housing. An intermediate position of the sphere between the oppositely disposed openings serves to block the flow of air.
