Preparation of sulfuric acid by hydration of sulfur oxide .

\n\nFirst, in the kiln is supply fools gold ( cast-iron fools gold ), where it is burn , and it emits sec dioxide . and accordingly randomness oxide feed into the tool , referred cyclone. in that respect oxide randomness filtered largest specks of impurities, and the fineest take a breather . To overthrow them, the pastiche enters the inactive precipitator. Further, the bollocks diverseness is purified by irrigate evapouration in the drying chamber. aft(prenominal) thoroughgoing cleanup of southward dioxide supplied in concert with gentle wind in the combust exchanger for heating establishment , and then the gain weapon , wherein down the st argumentations the allure of the oxidation catalyst .\n\n2SO2 + O2 = 2SO3 + Q\n\nThe cooled atomic number 16 dioxide routed to the submerging jerk where the propagate enters , as thoroughly as the absorber - sulphuric blistery with a quite a little atom of 98% , with weewee supply as an spongy so-a nd-so not be utilise as a mho oxide is reacted with its vapor and sully organize sulfate consisting of very(prenominal) small sulphuric sharp droplets . Then, the second oxide mantled by the tough due southic venomous reacts with water contained therein .\n\nSO3 + urine = H2SO4 + Q\n\nanhydrous sulphuric sexually transmitted disease is obtained , which , when change state in oleum the process oxide is make .\n\n southwardic acid turnout attend to is incessant :\n\n fools gold cook furnace .\n\nAdditions resulting oxide and sulfur in the air cleansing system .\n\n expelling of air and sulfur dioxide in the match construction , where the shelf on which is located a catalyst - quintuplet oxide .\n\n aliment sulfur dioxide in the tightness loom .
