METHOD OF ISOLATION MERCURY VAPORS FROM GASEOUS MEDIA Russian patent published in 1997 - IPC

FIELD: purification of air from mercury vapors. SUBSTANCE: freshly prepared microdisperse sulfur air sol with particle diameter up to 1 mcm is introduced into a gaseous medium to contact with mercury. Sulfur concentration in air sol is 0.1-3 g/cu.m. Most commonly, air sol is prepared by means of pyrotechnic generator, temperature of air sol being lower than ignition temperature of sulfur in contact with air oxygen. Method is suitable to demercurize air in quarters, production facilities, and mines. EFFECT: increased demercurization degree. 2 cl, 2 dwg
