Title: Improvements in or relating to processes for the production of nitric acid
IPC: C01B21/40
Filed: 1970-03-18
Abstract: 1298843 Nitric acid PINTSCH BAMAG AG 18 March 1970 [28 March 1969] 13133/70 Heading C1A A process for the preparation of nitric acid of two different concentrations, less than 75% and at least 98%, from the nitrous gases produced by the catalytic oxidation of ammonia comprises the steps of (1) condensing the water content of the gases as 20-45%, nitric acid; (2) adding oxygen to the gases and allowing the oxidation of NO to proceed initially in a first oxidation zone in which the gas is also contacted with the 20-45% acid so that sufficient NO 2  is chemically absorbed to form weak acid of the desired concentration as the first product; (3) allowing the remaining NO to oxidize in a second oxidation zone; (4) physically absorbing the resulting NO 2  in concentrated nitric acid; (5) separating the absorded NO 2  by distillation, liquefying it, and reacting it with air and weak nitric acid under pressure to form the concentrated nitric acid. The ammonia oxidation, and preferably the oxidation and absorption of the nitrous gases, are carried out at 2-15 atm. pressure. In the illustrated embodiment nitrous gases entering at a are cooled in heat exchanger 2 to condense out 35% nitric acid, mixed with air and passed into column 3 where they are oxidized and contacted with the 35% nitric acid. The weak acid, thereby concentrated to 55%, passes to column 4 where it is stripped of dissolved nitrogen oxides by the air entering the process from b, and may then pass to fractionating column 15 for further concentration by distillation under reduced pressure. A stream of weak acid also passes in a loop from column 4 to heat exchanger 1 where it is contacted directly with warm dry waste gases leaving the process, which remove some water from it, and indirectly with the entering nitrous gases which are thus pre-cooled. In the upper part of column 3 the oxidation of NO is completed, and the gases are then cooled in heat exchangers 20 and 5 and scrubbed with concentrated acid in column 6. The resulting solution is stripped in degasing column 8 and the NO 2  recovered is liquefied in condenser 11 and passed to autoclave 12, together with air from e, part of the 55% nitric acid formed in column 3, which collects in the lower part of the column, and the condensate formed in heat exchanger 7. Concentrated nitric acid formed in the autoclave at 50 atm. is fed into the absorption-desorption cycle via degasing device 13 and a corresponding amount of nitrogen oxide-free concentrated acid is withdrawn as product at g.

Filed: 1933-05-06
Abstract: 406,884. Controlling variable-speed gearing. FLEISCHEL, G., Bleneau, Yonne, France. May 6, 1933, No. 13259. Convention date, May 7, 1932. [Class 80 (ii).] An automatically controlled variablespeed transmission influenced by an engine control member such as a throttle is characterized in that the effective leverage through which the effect of one or more functional factors of the engine are transmitted to the control means 14 of the transmission is modified automatically as a function of the displacement of the control member 23 for regulating the power of the engine. In all arrangements described there appears the " main control or release lever 14 " of Specifications 356,139, 360,262, and 369,361 which, as shown in Fig. 1, by rocking to one side or the other into engagement with contacts 17<1>, 17<2> determines in which direction electric current will flow in a servomotor 7 and therefore which way, to change speed up or down, the control shaft 15 of a change-speed gear, not shown, will be rocked. The engine factor operative in the arrangement upon a vehicle shown in Fig. 1 is the speed thereof, but other factors, such as the load on the engine, the engine suction, or the temperature or pressure of cooling water or lubricating oil, may be used. An enginedriven governor 8 acts on one arm 12<1> of the release lever 14 and a control spring 9 acts on another arm 12<2> and these arms are curved so that the lever 14 is not moved when contact links 131 and 13<2> are swept over these arms in unison when a connecting rod 24 jointed to the accelerator pedal 23 is displaced longitudinally. The throttle 2 of the engine 1 is connected by a rod 22 to the pedal 23. The effective leverage of the governor 8 upon the release lever 14 is set directly by the engine control 23. In an arrangement shown in Fig. 11<a>, the load on the engine is manifested as manifold suction on a diaphragm 8<2>. In an arrangement shown in Fig. 12, there are operative in addition to the engine governor 8 and control spring 9 the pressure of lubricating oil in a cylinder 92 and a force taken from the vehicle brake system manifested as a pull in a rod 16<4>. The leverages are modified by the accelerator pedal 23. In Fig. 14, the invention is shown applied to the winding-drum 80 of a lift driven through disc-and-roller variablespeed gearing 3, 78 from an electric motor 1, the power supply of which is under control from a lever 23 through a rheostat, not shown. Change of load on the drum alters the current in a supply lead 77 and solenoid 8<1> which displaces through levers 13<1>, 13 the release lever 14 which directs current to the speedcontrolling servomotor 7. The leverage in the system is modified by shifting the control lever 23 of the power unit.
