Abstract: A method for converting an existing steam methane reformer (SMR) to produce hydrogen via ammonia cracking is provided. The method can include the steps of: providing the existing SMR, wherein the SMR was formerly used to produce hydrogen from a hydrocarbon feedstock; and improving the nitridation resistance of the inner surface of the equipment by adding a protective layer to an inner surface of equipment to be used in the existing SMR, wherein the equipment is selected from the group consisting of a catalyst tube, feed piping, a feed preheater, process gas heat exchangers, and combination thereof.

Abstract: A hydrogen production facility having equipment with a nitridation protective layer is provided. The hydrogen production facility can include a reformer configured to catalytically convert a feed stream into a product stream comprising hydrogen, the reformer having a plurality of catalyst tubes and a plurality of burners configured to provide heat to the catalyst tubes; means for providing the feed stream to the reformer from an ammonia source, wherein the feed stream comprises at least 90% of ammonia, wherein the plurality of catalyst tubes comprise a nitridation protective layer on an inner surface of the catalyst tubes.

Abstract: The present invention relates to a method for returning empty packaging, particularly bottles and cans, having a bulk import, in which the empty packaging is routed out of an input chamber through a transport device, rotating the empty packaging along its longitudinal axis past a recognition unit. The transport device for carrying out the method has a plurality of rollers which are arranged transversely with respect to the direction of transport and act as carriers for the empty packaging. The empty packaging is supplied to the detection array of the recognition unit in a field array. To avoid empty packaging being conveyed on top of other empty packaging, thereby blocking the detection of the bottom empty packaging by the recognition unit, the empty packaging undergoes a brief reversal of direction of rotation before its presentation to the detection array.

Abstract: The present invention relates to a unit for container return machines, having a conveying means for the longitudinal drive of a container in the direction of its longitudinal axis, and a rotational body arranged on each side of the conveying means, wherein, when the unit is in transportation mode, the container rests on the conveying means and is driven longitudinally, and, when the unit is in identification mode, the container rests on the rotational bodies and is driven rotationally. Each rotational body has the cross-section of a flattened circle, such that when the unit is in transportation mode, the container bears against at least one of the flattened surfaces of the rotational bodies.

Abstract: A tabular assembly base (2) is proposed, which serves for the detachable fitting of a valve unit (3). The assembly base (2) is modular in design and comprises a plurality of individual base segments (23) joined together as a rigid unit. The valve unit (3) comprises several valve modules (4). Underneath the base segments (23) several connection segments (25) are located which are associated with the valve modules (4). They possess load ducts (33) communicating with the valve modules (4) and having an electrical and/or fluid power functional unit (38) associated with them at least in part.

Abstract: A valve arrangement comprising several valve units placed in rows side by side in the a direction in a common row defining plane. Each valve unit comprises a base plate with supply and venting ducts extending therethrough and two mutually parallel spool receiving spaces each having a valve spool. The supply and venting ducts run in the partition, placed between the two spool receiving spaces, of the base plate and simultaneously communicate with the two spool receiving spaces. Such a valve arrangement may be manufactured with compact dimensions and have high flow through rates.

Abstract: Pollutant emissions produced during gas turbine power generation with a fuel gas from coal gasification are reduced by initially cooling the fuel gas to a temperature above the dewpoint but between 200.degree. and 400.degree. C. to condense alkalies on dust grains. In the fuel gas, HCl and HF are adsorbed on calcium carbonate and filtration removes the particulates. The fuel gas is reacted with oxygen in the presence of a carbon containing adsrobent to eliminate sulfur, and the flue gas after combustion is catalytically treated with a carbon containing adsorbent to remove nitrogen and sulfur oxides.

Abstract: An installation system of labeled conductors including plugs as well as connecting centers for permanent yet still flexible circuit connections, which also produce plug connections leading to a plurality of conductors. The system provides that (a) the connecting center includes contact rails directly connected to the leads of a conductor, which form a plurality of tongues for the socket contacts in socket plugs; (b) wherein the housing has the plug receivers receive the tongues in a recessed manner and forms protective collars fitted to the plugs; (c) and wherein at least one plug receiver is formed for connection to all contact rails.
