Abstract
СПОСОБ ОЧИСТКИ ГАЗОВ, СОДЕРЖАЩИХ ДИОКСИД СЕРЫ, ОТ ФТОРСОДЕРЖАЩИХ ПРИМЕСЕЙ контактированием с измельченным кальцийсодержащим поглотителем при повышенных температурах, отличающийс тем, что, с целью повышени степени очистки и уменьшени потерь диоксида серы, очистку ведут при 400-670°С с поддержанием в газе концентрации кислорода в интервале 0,01-0,05 об.% и в качестве поглотител используют оксид кальци .A METHOD FOR CLEANING GASES CONTAINING SULFUR DIOXIDE FROM FLUORINE-CONTAINING IMPURITIES by contacting with crushed calcium-containing absorber at elevated temperatures, characterized in that, in order to increase the level of sulfur dioxide loss, they clean up at a temperature difference of 400-6 ° C and have a temperature difference of 10.66 ° C; oxygen concentrations in the range of 0.01-0.05% by volume and calcium oxide as the absorber.
Description
Изобретение относитс к способам очистки SOj-содержащих газов от фторсодержащих примесей и может найти применение в производстве серной кислоты.This invention relates to methods for purifying SOj-containing gases from fluorine-containing impurities and may find use in the manufacture of sulfuric acid.
Цель изобретени - повышение степени очистки и уменьшение потерь диоксида серы.The purpose of the invention is to increase the degree of purification and reduce the loss of sulfur dioxide.
Пример. Очистка от фтора и его соединений газа, получаемого при термохимиlecKOM разложении фосфопшса.Example. Purification of fluorine and its compounds gas produced by thermochemolcom decomposition of phosphocing.
На очистку подают газ, содержаший 6,00/ SO 2,, 800 мг/нм фтора (0,08%), 0,03% О с температурой . После контактировани с известью фракционного состава 0,010 ,20 мм содержание 50 и фтора составл ет 5,98% и 7 мг/нм (0,001%), соответственно . Степень очистки от фтора составл ет 99%, потери SOj. 0,5%.A gas containing 6.00 / SO 2 ,, 800 mg / nm of fluorine (0.08%), 0.03% O with temperature is fed to the purification. After contacting a fractional composition of 0.010, 20 mm with lime, the content of 50 and fluorine is 5.98% and 7 mg / nm (0.001%), respectively. The degree of purification from fluorine is 99%, loss of SOj. 0.5%.
