Abstract
A process of gas reaction (e.g. purification of ammonia synthesis feed gas), involving a feed gas mixture containing a component exothermically reactive with oxygen and requiring a minimum temperature before two or more of its components react exothermically with each other, includes burning a proportion of a component exothermically with oxygen so that heat exchange of reacted gas with feed gas raises the temperature of the latter to the minimum required for said reaction. The burning of a component with oxygen and the exothermic reaction between components may be carried out at the same time, the oxygen being mixed with the feed gas mixture, preferably before heat exchange with reacted gas mixture. The temperature of the reacted gases is preferably 50-100 DEG F. above that of the feed gas mixture. In the case of the purification of an ammonia synthesis feed gas containing H2, N2, CO2 and CO (0.1-0.3 mol per cent), the H2 is burnt with O2 to form water, in the presence of a catalyst, and heat exchange between the reacted and feed gases raises the temperature of the latter to the minimum required for the reaction of H2 with CO and/or CO2 at a pressure of 100-400 p.s.i. and 300-600 DEG F. to form methane and water, thereby removing CO and CO2 impurities from the gas mixture.ALSO:A process involving a feed gas mixture containing a component exothermally reactive with oxygen and requiring a minimum temperature before 2 or more of its components react exothermally with each other, includes burning a proportion of a component exothermally with oxygen so that heat exchange of reacted gas with feed gas raises the temperature of the latter to the minimum required for said reaction. The burning of a component with oxygen and the exothermal reaction between components may be carried out at the same time, the oxygen being mixed with the feed gas mixture preferably before heat exchange with reacted gas mixture. The temperature of the reacted gases is preferably 50 DEG -100 DEG F. above that of the feed gas mixture. The example relates to an ammonia gas synthesis process.
