Title: Denitrification catalyst regeneration, esp. to remove arsenic cpds. - by supplying reducing agent and removing hot impurity vapour, then supplying oxidant
Inventor: SCHMELZ HELMUT DR
IPC: B01J38/08
Filed: 1992-06-22
Abstract: Regeneration of a deactivated de-NOx catalyst (I), esp. (I) deactivated by As, comprises passing a reducing agent (II) over (I), removing the heated vaporised impurities (III) and then passing an oxidant (IV) over (I). (II) is pref. NH3 or hydrocarbon, pref. excess hydrocarbon; and (III) is air. The temp. of (I) is over 190 deg.C during treatment with (II) and 190-650 deg.C during treatment with (IV). (III) are removed in the (II) stream. During regeneration an As-binding additive, esp. limestone is added to the combustion plant preceding (I). ADVANTAGE - The initial activity of (I) is (largely) restored. In an example, during regeneration of As-deactivated (I), limestone was added to the combustion plant to reduce the concn. of free As2O3 in the flue gas. As2O5 bound to (I) was reduced to As2O3 by supplying more than the stoichiometric amt. of NH3 for the catalytic redn. process. The As2O3 vaporised at the (I) operating temp. of ca. 350 deg.C and was removed in the flue gas stream. The NOx:NH3 ratio was then reduced to the usual value of ca. 1.1. The atmos. O2 supply was then increased to oxidise V4+ to V5+ and restore the original activity.

Title: Gas sepn. column has incoming cone-shaped sprays - which change to bubble formation to mix in second zone where sepn. of phases effected without loss of product purity, or higher throughput
IPC: B01J10/00
Filed: 1992-11-05
Abstract: Flooded sections are incorporated within a contact sepn. column. In a process to transfer a substance between a vapour and a liq., a first absorbent or reactant present in a liq. phase within a reaction zone is mixed in a stream with a drying pressurised gas to produce gas bubbles, with a resulting exchange matter at the inter-phase boundaries. The novelty is that the gas which is to be treated by cleaning or the removal of moisture, or a similar (second) medium, enters to form an extended cone-shaped (gas) jets in a first mixing zone with the inflowing drying or similar (first) pressurised reactant, to form an upwardly directed spray. The spray-film flow (43) jet pattern changes to form bubbles, and this bubble flow (44) is guided into a second condensation area serving as a bubble flow serving mixing zone (viz.41), where the phases are sepd. The sepd., enriched liq. phase is removed and sepd. from the gaseous phase (52). Appts. is also claimed. USE/ADVANTAGE - Process and appts. to transfer substance between a vapour and a liq. The system facilitates the construction of small contact sepn. columns without sacrificing product purity, or permits a larger through of material per unit time and the same quality levels as existing contact separation columns.

Pref. the alarm is activated upon detected opening of a door or window after a delay interval sufficient to allow de-activation, e.g. via a coded key. ADVANTAGE - Ensures security is maintained upon loss of normal supply voltage.

IPC: B60G17/015
Filed: 1993-03-31
Abstract: The flow of a damper fluid through a flow channel is detected and- when the flow rate of the fluid reaches a preselected lower limit value, an enabling signal is produced, which allows a changeover signal possibly available at that moment for adjusting the damper characteristic to become effective. In one arrangement (figure 2) simple leaf springs 42, 44 deflect under the influence of fluid flow through passages 37, to break an electric circuit, or make contact via electrically conductive tubes 36 to make the circuit when the fluid flow reaches said lower limit, thereby producing said signal. In an alternative arrangement (figure 4) a single leaf spring is used, one electrical lead (46) being connected to the leaf spring (42) and another lead (48) being connected to a conductive tube (36).   <IMAGE>
