Abstract: A method of manufacturing an object by joining a first component and a second component. The first component comprises metal powder with a first alloy composition and a first soluble binder, and the second component comprises metal powder with a second alloy composition and a second soluble binder. They may further comprise ceramic powder. At least one of the surfaces to be joined is dissolved before they are brought in contact, or a mixture of metal powder with a third alloy composition and a dissolved third binder is arranged there between. The chemical differences between the first, second, and third alloy compositions are within predetermined limits. The components are sintered or oxidized together whereby it is possible to obtain an object wherein the transitions between the material phases from the joined components are close to inconspicuous when analysed with scanning electron microscopy.

Abstract: The invention relates to a method of controlling a power limit (P) of a circulating pump (1) comprising a critical component (4) and a first temperature sensor (5) arranged and configured to measure the temperature of the critical component. The first temperature sensor may be arranged on top of, below, integrated with, or in the vicinity of the critical component. The method comprises monitoring the temperature (T) of the critical component by use of the first temperature sensor and using an output signal (6) from the first temperature sensor as a first temperature input signal (7) to a controller (8). By use of the controller and based on the first temperature input signal, the power limit of the circulating pump is controlled in accordance with a performance derating curve for the circulating pump. The invention further relates to a system (3) for controlling a power limit of a circulating pump by use of such a method.

Abstract: The invention relates to a structured catalyst for catalyzing steam methane reforming reaction in a given temperature range T upon bringing a hydrocarbon feed gas into contact with the structured catalyst. The structured catalyst comprises a macroscopic structure, which comprises an electrically conductive material and supports a ceramic coating. The macroscopic structure has been manufactured by 3D printing or extrusion and subsequent sintering, wherein the macroscopic structure and the ceramic coating have been sintered in an oxidizing atmosphere in order to form chemical bonds between the ceramic coating and the macroscopic structure. The ceramic coating supports catalytically active material arranged to catalyze the steam methane reforming reaction, wherein the macroscopic structure is arranged to conduct an electrical current to supply an energy flux to the steam methane reforming reaction. The invention moreover relates to methods of manufacturing the structured catalyst and a system using the structured catalyst.

Abstract: A multi-pump control system with a control module, a processing module, communication interface, and a storage module. The system is configured to change a number n of running pumps, and receive a signal indicative of a power consumption P and information about a speed ω of one of the n running pumps before and after two different changes of the number n of running pumps. The system is configured to determine, before and after at least two different changes of the number n of running pumps, without a measurement of a differential pressure Δp and of a flow Q, two approximated pump characteristics Pn and Δ{tilde over (p)}n, wherein each of the approximated pump characteristics Pn and Δ{tilde over (p)}n is unambiguously defined by a pair of parameters (θ1, θ2; θ3, θ4). The system is configured to store the pair of parameters (θ1, θ2; θ3, θ4) for each of the determined approximated pump characteristics Pn and Δ{tilde over (p)}n.
