  • Publication number: 20130336872
    Abstract: The invention relates to a process and apparatus for preparing nitric acid by catalytic oxidation of NH3 by means of oxygen and subsequent reaction of the NOx formed with an absorption medium in an absorption tower, which comprises a catalyst bed for N2O decomposition arranged in the process gas downstream of the catalytic NH3 oxidation and upstream of the absorption tower in the flow direction and a catalyst bed for NOx reduction and effecting a further decrease in the amount of N2O arranged in the tailgas downstream of the absorption tower in the flow direction, wherein the amount of N2O removed in the catalyst bed for N2O removal arranged in the process gas is not more than that which results in an N2O content of >100 ppmv and a molar N2O/NOx ratio of >0.

  • Publication number: 20120034148
    Abstract: Improved reactors for catalytic, exothermic gas phase reactions with, as seen in the flow direction of a feed gas, which contains at least one oxidant and at least one component to be oxidized, an entry zone (1), a reaction zone (2) comprising at least one catalyst (4) and an exit zone (3) for the product gas are described. The reactors, at least in the area of the entry zone (1), have means, for example insulating jackets (6) and/or devices for the transport of cooling agents, which decrease the transport of heat produced in the reaction zone (2) into the entry zone (1) and thus decrease the risks of pre-ignition of the feed gas mixture employed or of the course of undesired side reactions in the entry zone (1) and/or wherein the inner walls of the reactor, at least in the area of the entry zone (1), are elaborated from inert material. The feed gas enters into the entry zone (1) as a homogeneous gas mixture with respect to its substance composition via one or more feed lines (30).

  • Patent number: 8057444
    Abstract: A device for holding a cannula and for the releasable arrangement on an injection pen, with a basic body, wherein the cannula is arranged in the basic body in a manner such that it is substantially non-displaceable along the central axis thereof. Latching provisions are arranged on the circumferential surface of the basic body. The latching provisions are designed in order to be engaged behind by mating latching provisions of a release mechanism of a storage or disposal container for the device.

  • Publication number: 20100166631
    Abstract: Improved reactors for catalytic, exothermic gas-phase reactions, which comprise, viewed in the flow direction of a feed gas, an inlet zone (1), a reaction zone (2) containing at least one catalyst (4) an outlet zone (3) for the product gas, are described. The reactors are provided in the region of the inlet zone (1) or in the region of the inlet zone (1) and the reaction zone (2) with means, for example an insulating liner (6) and/or apparatuses for the transport of cooling media, which reduce heat transport from the reaction zone (2) into the inlet zone (1) and thus reduce the risk of preignition of the feed gas mixture used or occurrence of undesirable secondary reactions in the inlet zone (1) and/or the interior walls of the reactor in the region of the inlet zone (1) or in the region of the inlet zone (1) and the reaction zone (2) consist of inert material.

  • Publication number: 20040072048
    Abstract: A configuration and method for the wire-free supply of electric power to a large number of sensors and/or actuators mounted on a machine includes a micro fuel cell with associated fuel tank integrated into the sensors/actuators and converting the stored fuel, preferably methanol, into electric power to supply the sensor. Also included is a sensor or actuator with such an integrated micro fuel cell and fuel tank. Further included is a system for a machine, in particular an automatic production machine, having a large number of sensors/actuators equipped with a transmitting device and/or receiving device communicating through radio signals with a central transmitting and/or receiving device connected to a process computer belonging to the machine, and a micro fuel cell with associated fuel tank integrated into the sensors/actuators and converting the stored fuel into electric power to supply the sensor.

  • Patent number: 4871356
    Abstract: A retentive catheter having a cannula tube through which medications may be injected into a patient. A mandrin may be left in the retentive catheter during the injection. The medication is injected through an injection port and flows through a fluid channel between the mandrin and the cannula tube and is discharged from the cannula tube through a valve. The valve may be of the nonreturn type. The mandril tip prevents blood components from entering into the cannula tube. The protection against contamination is increased because the mandrin need not be removed from a proposed injection.
