Abstract: A method and a system for separating a feed flow which contains at least hydrogen and a hydrocarbon with three or four carbon atoms per molecule, in particular propane, propylene, propadiene, butane, 1-butene, 2-butene, and/or 1,3-butadiene. The condensed feed flow is cooled over multiple cooling steps in at least two heat exchangers and is then separated into a condensate and a residual gas flow after each cooling step. The at least two heat exchangers are operated at least two different temperature levels, wherein a hot heat exchanger is operated at an average temperature level, and a cold heat exchanger is operated at a lower temperature level. An internal refrigerant which is made of a part of one of the condensate flows and a part of one of the residual gas flows, is used to dispense a part of the heat from the cold heat exchanger.

Abstract: A hood hinge for a motor vehicle includes a first part attached to a vehicle body part and a second part attached to a front hood. A lifting mechanism is configured to extend the attachment parts from a starting position into a cushioning position in which the front hood is raised from the starting position. A limiter exerts a limiting force on the attachment parts for limiting an extension movement thereof. A deformation element deforms when the force of the limiter acts on at least one attachment part. A stop may contact a counter stop for limiting the deformation of the deformation element.

A lift mechanism is configured to extend the attachment parts from a starting position into a cushioning position in which the front hood is raised from the starting position. The lift mechanism includes a first lever coupled to one of the attachment parts and a second lever coupled to the other attachment part for rotation about a rotational axis respectively. The first and second levers are rotatably coupled about a rotational axis. A traction element generates a traction force by extension of the attachment parts, which limits the extension movement thereof.

Abstract: A process and plant are proposed for separating a feed mixture predominantly or exclusively containing carbon monoxide and hydrogen, in which the feed mixture is subjected to a cryogenic separation process in which a carbon monoxide-rich liquid and at least one residual gas mixture which is depleted in carbon monoxide and enriched in hydrogen, in comparison with the feed mixture, are formed. It is intended that the at least one residual gas mixture is subjected to a membrane separation process in which at least one hydrogen-rich permeate and at least one carbon monoxide-rich retentate are formed, wherein the or at least one of the carbon monoxide-rich retentates is recirculated to the cryogenic separation process.

Abstract: The invention relates to a method for generating an alkene, in which a hydrocarbon-comprising feed material is subjected to a dehydrogenation and a product material comprising at least one alkene is generated. A gas stream coming from an adsorber is cooled by a gas stream which comprises the feed material, and the gas stream coming from the adsorber is cooled by a condensed component of the gas stream coming from the adsorber in a first cooling phase. Feed material is cooled in a second cooling phase by a condensed component of the gas stream coming from the adsorber. The flow of the condensed component of the gas stream coming from the adsorber, fed to the first and/or second cooling phase, is varied depending on the temperature of the gas stream leaving the first cooling phase which comprises the feed material and which is fed to the dehydrogenation.

Abstract: The invention relates to a method for purifying synthesis gas, in particular for ammonia synthesis, wherein a partial stream (26) of an H2-rich, CO-containing synthesis gas stream is burned, in particular to generate electrical energy, and wherein at least one component contained in the remaining H2-rich, CO-containing synthesis gas stream (26a), in particular in the form of carbon dioxide, methanol and/or water, is absorbed by an adsorber at low temperatures, after which said absorbed component is desorbed from the adsorber by flushing using nitrogen (33) at higher temperatures. According to the invention the H2-rich partial stream (26) is diluted using the nitrogen (35) used for the flushing before being burned. The invention further relates to a system (1) for purifying synthesis gas, in particular for ammonia synthesis.

Abstract: With a lock for a front hood of a motor vehicle, a locking pawl engages about a rotary latch. This engagement creates a positive connection of the locking pawl to the rotary latch perpendicularly to their intended movement directions. This prevents that during a crash of the motor vehicle the locking pawl is separated from the rotary latch and the lock therefore unlocked.
