Abstract: A method for producing hydrocarbons includes subjecting a first feed stream to steam cracking to obtain a first product stream, and subjecting an ethane-containing second feed stream to oxidative dehydrogenation to obtain a second product stream. A portion of the first product stream is subjected to a deethanization or a depropanization separately from the second product to obtain a lighter fraction and a heavier fraction. A demethanization feed stream is formed by combining at least a portion of the lighter fraction and at least a portion of the second product stream and is subjected at least in part to demethanization. Partial oxygen removal is carried out during the formation of the demethanization feed stream. The oxygen removal is carried out downstream of the combining step.

Abstract: A method for producing one or more hydrocarbons, includes subjecting a first feed stream to a steam cracking to obtain a first product stream and subjecting a second feed stream containing ethane to an oxidative dehydrogenation to obtain a second product stream At least a portion of the first product stream is subjected to a treatment to obtain hydrocarbon fractions. The treatment includes a selective hydrogenation of hydrocarbons having two carbon atoms and a demethanization. At least a portion of the second product stream is subjected to a trace removal, which comprises the removal of oxygen and/or acetylene, to obtain an subsequent stream. At least a portion of the subsequent stream is fed to the treatment at a position downstream of the selective hydrogenation and upstream of the demethanization. A portion of the subsequent stream is subjected to a carbon dioxide removal upstream of the feed point into the treatment.

Abstract: A technology for creating, replicating and/or controlling avatars in an extended-reality (ER) environment can include methods, extended-reality-compatible devices, and/or systems configured to generate, e.g., via an ER-compatible device, a copy of a representation of a user, e.g., a primary avatar, and/or an object in an ER environment, to initiate a recording of the graphical representation of the user or object according to a schema; to produce a copy of the recording of the graphical representation of the user as a new graphical representation of the user, e.g., a new avatar, in the ER environment; and to control the new graphical representation of the user at a first location in the ER environment. In examples, the technology enables moving the graphical representation of the user around the ER environment while the new graphical representation of the user performs motion and/or produces sound from the copy of the recording.

Abstract: A technology to have better experiences, e.g., beyond-arm's-length experiences, with fine-tuned interactions in an extended-reality environment can include methods, extended-reality-compatible devices, and/or systems configured to generate, e.g., via an extended-reality-compatible device, a copy of a representation of an object in an extended-reality environment, to initiate control of the copy of the representation of the object according to a schema; and to control the copy of the representation of the object at a first location in the extended-reality environment, e.g., the first location including a location beyond-arm's-length distance from a second location in the extended-reality environment, the second location being a location of an avatar or representation of a user and/or a controller of the extended-reality-compatible device.

Abstract: In one embodiment, a computing system may receive input data from several artificial-reality systems used by participants to participate in a virtual meeting. The input data may include audio data and sensor data corresponding to the participants while they are in the virtual meeting. The computing system may determine meeting characteristics based on input data. The meeting characteristics may include individual behavioral characteristics for each participant and communal characteristics associated with the participants as a group. The computing system may determine an action to improve a meeting characteristic according to a predetermined criteria and generate an instruction for performing the action. The computing system may send the instruction to one or more of the artificial-reality systems used by the participants. The instructions may be configured to cause an application running on each of the artificial-reality systems that receives the instruction to perform the action.

Abstract: Techniques are described herein that enable a user to provide speech inputs to control an extended reality environment, where relationships between terms in a speech input are represented in three dimensions (3D) in the extended reality environment. For example, a language processing component determines a semantic meaning of the speech input, and identifies terms in the speech input based on the semantic meaning. A 3D relationship component generates a 3D representation of a relationship between the terms and provides the 3D representation to a computing device for display. A 3D representation may include a modification to an object in an extended reality environment, or a 3D representation of a concepts and sub-concepts in a mind map in an extended reality environment, for example. The 3D relationship component may generate a searchable timeline using the terms provided in the speech input and a recording of an extended reality session.

Abstract: A method for obtaining an ethylene product in a supercritical state is proposed, in which method a gas mixture containing predominantly or exclusively ethylene and ethane is separated in a distillation column (1), which is operated at a distillation pressure level of from 5 to 15 bar, into an overhead product containing predominantly or exclusively ethylene and a bottom product containing predominantly or exclusively ethane, the overhead product being withdrawn in the gaseous state from the head of the distillation column (1) and a first portion thereof being liquefied and returned as reflux to the distillation column (1) and a second portion thereof being converted into a supercritical state and being used as the ethylene product.

Abstract: A method is proposed for compressing a gas in stages in a compressor arrangement (100, 200, 300, 400) having a plurality of compression stages (I-VI) which are connected together sequentially by a main line (1) and in which the gas, guided through the main line (1), is respectively compressed from a suction-side pressure level to a pressure-side pressure level and is heated by this compression from a suction-side temperature level to a pressure-side temperature level, wherein a feedback amount of the gas, guided through the main line (1), is at least temporarily removed from the main line (1) downstream of one of the compression stages (V), is fed to an expansion process, and is fed back into the main line (1) upstream of the same compression stage (V).
