    摘要: The invention relates to a method for analyzing the composition of a gaseous stream comprising at least two gaseous components, one of which is methane; and to a sensor array and a gas sensor comprising such sensor array. The method comprises contacting the gaseous mixture with a sensor, wherein the sensor comprises a sensor array comprising at least two sensor elements, wherein each of said sensor elements comprises a transducer coated with a coating comprising a polymeric material having at least one property that is responsive to one or more of said gaseous components when exposed thereto, wherein said sensor elements differ at least in the composition of the coating, providing an energy input to said transducers that is converted to output signals based on said property, and obtaining said output signals.

    摘要: The invention is directed to a method for processing asbestos-containing steel scrap into useful products, which products can be handled in a safe manner. In accordance with the present invention the asbestos-containing steel scrap is melted in a furnace, which results in destruction of the asbestos fibers. It has been found possible to carry out such a process in an economically feasible manner. In accordance with the invention asbestos-containing steel is heated to high temperature so that the steel melts. As a result the asbestos will be converted into harmless material, which allows for safe handling and processing of the resulting products.

    摘要: Disclosed is a method for the continuous impregnation of wood elements, such as wood chips. The method comprises the subsequent steps of subjecting the wood elements to vacuum, to contact with acetylation fluid, and to impregnation pressure. Preferably, the process is conducted in a plant having conveyors, such as transportation screws, in suitable positions between the zones in which the subsequent process steps are conducted. The impregnation method is used in connection with the acetylation of the wood elements, and preferably is followed by a continuous acetylation process conducted in an acetylation reaction zone downstream of the zone where the impregnation is conducted.
