    摘要: An electric circuit for providing a selection signal being used to select a control value of a control variable which oscillates, at steady state, about a reference value about a first control value and a second control value with a first period duration comprises a first differential circuit which provides a first current being dependent on a difference between the first control value and the reference value. The electric circuit further comprises a second differential circuit which provides a second current being dependent on a difference between the reference value and the second value and a first node at which a differential current between the first current and the second current is formed. The differential current forms the selection signal indicating if the first control value or the second value is to be selected in order to minimize a difference between the reference signal and control variable. A first current mirror circuit of the electric circuit is connected between the first differential circuit and the first node in order to pass the first current to the first node and a second current mirror circuit and a third current mirror circuit of the electric circuit are connected in series. The second and third current mirror circuits are connected between the second differential circuit and the first node in order to pass the second current to the first node.

    摘要: The invention relates to a tube bundle reactor with a flat feed hood. Alternatively, the release hood may also have a flat design. The flat design reduces the heat of reaction which arises in the hood in the case of reaction types which take place not only in the tube bundle (uncatalyzed reactions and reactions with homogeneously distributed catalyst). This greatly suppresses undesired reactions which already take place in the hood owing to accumulated heat, which achieves a higher selectivity in the case of thermally sensitive reactions. In addition, the thermal distribution within the hoods can be controlled precisely.The tube bundle reactor comprises a tube bundle which has a feed end which is connected to a feed hood of the tube bundle reactor, wherein the feed hood is configured in a flat design with a cross-sectional area at the feed end and an internal volume, and the ratio of internal volume to cross-sectional area is less than 0.35 m. The invention is further implemented by means of a process for operating a tube bundle reactor, comprising: introducing a reactant mixture into a tube bundle and converting at least a proportion of the reactant mixture within the tube bundle to a product. The introducing comprises: feeding the reactant mixture into an interior of a feed hood of the tube bundle reactor and passing the reactant mixture on into a feed end of the tube bundle in the form of a fluid stream. The fluid stream has a cross-sectional area on entry into the feed end, and the interior of the feed hood through which the fluid stream flows has an internal volume; where the ratio of internal volume to cross-sectional area is less than 0.35 m.
