Abstract

<PICT:0803026/III/1> <PICT:0803026/III/2> In a gaseous reaction plant hot-pressurized waste gases are used to compress incoming process gases entering inlet 2 by means of a pressure exchanger 1, the compressed gas together with gas from an inlet duct 8 passing to an exothermic reaction chamber 7. The resulting mixture is passed to a separator 11 which removes the product gas and returns the waste gases to the pressure exchanger via a heat exchanger 9 and duct 14. The pressure exchanger 1, Fig. 1, has transfer passages 1A and an inlet duct 2 leading to a rotary member with cells 3 in which the process gas is carried in the direction of the arrow 4 until the process gas is compressed by waste gases received from the duct 14, the compressed gas then passes by duct 6 to the reaction chamber 7. An exothermic reaction takes place in the reaction chamber in the presence of a suitable catalyst and the waste and product gases may pass through a heat exchanger 9, a cooler 10 and the separator 11. The waste gases on returning are reheated by passing through the hot pass of the heat exchanger 9 and are exhausted, at low pressure, through duct 15. For the preparation of nitric acid from air and ammonia entering inlets 2 and 8 respectively the nitric oxide formed in the reaction chamber 7 is absorbed in the separator 11 by water from inlet 12 to give a nitric acid solution which leaves by outlet 13. In a modification, Fig. 2, the waste gases do not pass through the heat exchanger on leaving the separator 11. Instead, the waste gases are mixed in a combustion chamber 16 with a fuel from an inlet 17 and burnt with air from duct 18 lead off from the main air supply duct 6 before entering the pressure exchanger 1 by duct 14.
