Abstract: A method for operating a TSN-enabled network coupling element, in particular, a TSN bridge, which is designed to receive redundant data packets. The method includes ascertaining at least one number of expected, non-received data packets via the TSN-enabled network coupling element, and transmitting the ascertained number of expected, non-received data packets from the TSN-enabled network coupling element to a control instance.

Abstract: A communication method between subscribers of a network having multiple components of a mechatronic system, wherein payload data are communicated between the subscribers via the network by messages, and payload data of multiple subscribers are combined in a sum frame message and the sum frame message is sent to the subscribers. To use network resources more efficiently, a configurable routing structure is used to route the messages, said routing structure containing at least one partial route, and at least one partial message pertaining to this partial route is composed that, as a sum frame partial message, contains just payload data from subscribers of this partial route, the sum frame partial message is routed via this partial route and subscribers of the partial route can each extract their payload data from the sum frame partial message and/or write said payload data to the sum frame partial message.

Abstract: A method is provided for fractionating a feed gas containing hydrogen and carbon dioxide, from which feed gas carbon dioxide is largely selectively removed by scrubbing in a first gas scrubber using a sulphur-free scrubbing agent, wherein a scrubbing agent stream laden with carbon dioxide and co-absorbed hydrogen is obtained which is subsequently expanded in an expansion vessel in order to convert co-absorbed hydrogen into the gas phase. The characterizing feature of the method is that the hydrogen-containing gas phase is drawn off from the expansion vessel and admixed with a sulphur-free gas mixture containing hydrogen and carbon dioxide, which gas mixture arises in a second gas scrubber operated in parallel to the first as a product at a pressure which is lower than the pressure of the feed gas.

Abstract: A furnace for steam reforming a feed stream containing hydrocarbon, preferably methane, having: a combustion chamber, a plurality of reactor tubes arranged in the combustion chamber for accommodating a catalyst and for passing the feed stream through the reactor tubes, and at least one burner which is configured to burn a combustion fuel in the combustion chamber to heat the reactor tubes. In addition at least one voltage source is provided which is connected to the plurality of reactor tubes in such a manner that in each case an electric current which heats the reactor tubes to heat the feedstock is generable in the reactor tubes.

Abstract: A method for producing urea. A methane-containing feed gas stream is reacted with oxygen by partial oxidation to form a synthesis gas stream containing hydrogen and carbon monoxide. The carbon monoxide is reacted with water in a water gas-shift reaction to form carbon dioxide and hydrogen. The synthesis gas stream is separated into a first synthesis gas substream a second synthesis gas substream. The first synthesis gas substream is subjected to pressure-swing adsorption to separate hydrogen and the second synthesis gas substream is subjected to temperature-swing adsorption to separate carbon dioxide. The separated is reacted with nitrogen to form ammonia and the ammonia is reacted with the carbon dioxide to form urea.

Abstract: A process and system for the generation of synthesis gas that is provided, in particular, for preparing hydrocarbon-containing fuel, ammonia or urea. The process follows the steps of providing a first feed gas stream of methane and reacting the first feed gas stream with steam in a reforming step, obtaining a synthesis gas stream of CO and H2. It is further provided that at least one first substream is separated off from the feed gas stream before the reforming step, the first substream is then burnt with a second feed gas stream of at least 95% by volume oxygen to give an exhaust gas stream comprising CO2 and water, and at least one part of the exhaust gas stream is recirculated to the feed gas stream after the first substream is separated off.

Abstract: A process for producing synthesis gas, by providing a feed gas stream, the feed gas stream including a hydrocarbon, preferably methane, and steam; heating of at least one part of the feed gas stream in a first steam reformer using heat of combustion; and converting of the heated feed gas stream into a synthesis gas stream of CO and H2 in a reforming step. At least one part of the feed gas stream is heated outside the first steam reformer, at least partly using electric energy.

Abstract: The invention relates to a method for fractionating a feed gas (1) containing hydrogen and carbon dioxide, from which feed gas carbon dioxide is largely selectively removed by scrubbing in a first gas scrubber (A1) using a sulphur-free scrubbing agent (3), wherein a scrubbing agent stream (4) laden with carbon dioxide and co-absorbed hydrogen is obtained which is subsequently expanded in an expansion vessel (D1) in order to convert co-absorbed hydrogen into the gas phase (9). The characterizing feature of the method is that the hydrogen-containing gas phase (9) is drawn off from the expansion vessel (D1) and admixed with a sulphur-free gas mixture (17) containing hydrogen and carbon dioxide, which gas mixture arises in a second gas scrubber (A2) operated in parallel to the first as a product at a pressure which is lower than the pressure of the feed gas (1).

Gas (1) is sent from the bottom to the top and washing agent (2) is sent from the top to the bottom through the washing column. At least two washing sections (WS1, WS2) are arranged on top of one another in the washing column (T). The top section (WS2) is bounded at the bottom by a riser base (K), from which a portion of the washing agent that is charged into the top washing section can be introduced as washing agent into the lower washing section (WS1). Another portion of the washing agent can be removed from the washing column (T) via a lateral drain (4). The top washing section (WS2) is connected to the lower washing section (WS1) by an overflow (U), via which charged washing agent from the riser base (K) can be introduced into the lower washing section (WS1).
