Do the desulfurization process and the alcoholification process, which are used for purifying the feed gas in ammonia synthesis plants, fall under the oxidation processes and hydrogenation processes respectively, among the key processes that are subject to strict supervision? 1. The desulfurization process employs the wet oxidation method. The principle of this process is to use an alkaline desulfurization solution to remove H2S from semi-water gas, thereby purifying it. The desulfurization solution that has absorbed H2S is sent to a regeneration tank, where it mixes with air through an injector to undergo oxidative regeneration; the regenerated desulfurization solution is then reused. 1.1 Its main reaction equations are: the absorption of hydrogen sulfide by an alkaline solution – Na2CO3 + H2S = NaHS + NaHCO3; and the oxidative catalytic reaction in the liquid phase – 2NaHS + O2 = 2NaOH + 2S↓. 2. The process principle of alcohol hydroformylation is that CO, CO2, and H2 present in the syngas undergo chemical reactions to produce methanol under certain temperatures, pressures, and in the presence of a catalyst. 2.1 Its main reaction equations are CO + 2H2 = CH3OH and CO2 + 3H2 = CH3OH + H2O
