Title: Waste gas purificn. - by oxidative scrubbing using hydrogen per:oxide to remove nitrogen oxide(s), heavy metals and organic cpds.
Inventor: CURTIUS FRITZ
IPC: B01D53/64
Filed: 1990-11-06
Abstract: Purifin. of waste gas by oxidative scrubbing using H2O2 to produce HNO3 from nitrous gases, e.g. flue gas from refuse incineration, is carried out in 2 stages, comprising (1) prodn. of NO2 by countercurrent scrubbing with HNO3 and HNO2 according to the equation HNO2 + HNO3 = 2 NO2 + H2O; and oxidising the nitrous gases and other harmful impurities by oxidative scrubbing with H2O2 in dil. HNO3. In stage (1), NO2 is produced in such an amt. that the amt. of NOx to be sepd. in stage (2) has a NO/NO2 ratio of 1:1 or the NOx conc., of the purified gas is regulated. NO2 formation is controlled by the amt. of scrubbing liquor in stage (1). Countercurrent packed scrubbers or plate columns are used in both stages. The HNO3 neeeded is supplied as vapour and is produced in stage (2), by the reaction NO + NO2 + 2 H2O2 2 HNO3 + H2O; pref. by countercurrent contact, using excess H2O2. The HNO2 is prepd. by absorbing the mixt. of NO and NO2 produced in the liquid and continuous exchange with the gas in stage (1). The scrubbing liquor from stage (1) is recycled to an earlier scrubbing stage. In stage (2), the scrubber has inserts ensuring that NO is absorbed by H2O2 first, then other impurities, e.g. Hg and other heavy metals, dioxins and furans, are oxidised, pref. using more than the stiochiometric amt. of H2O2. Hg is removed quantitatively with H2O2 and HNO3 by increasing the packing. The efficiency of stage (2) is increased by increasing the H2O2 concn. and reducing the amt. of liq. USE/ADVANTAGE - The process is also claimed for treating waste gas from HNO3 mfr. NOx, heavy metals, e.g. Hg, and organic Cl cpds., and esp. dioxins and furanes, are removed in an integrated process

Title: Waste water pumping system - has non-return valves in outlet pipe to reduce pumping energy requirements
Inventor: TRIMBORN ROLF
IPC: E03F5/22
Filed: 1991-02-02
Abstract: Waste water which collects in a manhole (1) is pumped out by means of a pump (2), wich is actuated by compressed air, which is supplied through the connection (5). The outlet pipe from the pump (2) is divided into sections (I,II,III) by non-return valves (6,7). The non-return valves prevent any water in the pipe from flowing back into the manhole (1) when the pump (2) has been shut down. This feature reduces the energy consumption of the pumping system since the pressure head of the water in the outlet pipe is conserved. USE/ADVANTAGE - Pumping of waste water by a method which reduces energy requirements.

Title: Bolted joint with elastically deflected flanges - uses elasticity to maintain bolt tension and prevent loosening of bolts
Inventor: BRENDEL HUBERT DR ING
IPC: F16B2/00
Filed: 1991-03-28
Abstract: The initial tension in the bolts of a bolted joint is maintained in the following way. A bolted joint is made between two structural elements (7) and (8) by means of flanges (5) and (6), with a plain hole in one flange and a tapped hole in the other flange. One of the flanges (7) has a small dia. blind hole (4) on each side of the bolt hole. These blind holes (4) receive flanged tubular dowels (2). When the flanges are bolted together a gap (11) is formed between the flanges. This gap is reduced by tightening the bolt (9) so that the flanges are elastically deflected. This elastic deflection maintains the tension in the bolt (9) and prevents it from becoming loose. USE - Bolted joints.
