U and Sept. 14, PROCESS for obtaining ammonium sulpluxte and sulphitein tlie purification of crude coal-gas, coke-oven gas, andsimilar gases consists in passing the gas, previously freedfrom tar, over a heated oxidising substance such asbog-iron-ore, and causing tlie oxides of sulphur whichare produced to combine with free ammonia. A part ofthe ammonia is present in the gas which jiasses over theoxidising substance, and a furtlier quantity of ammoniais obtained by treating tlie liquor, collected in separatingthe tar, with slaked lime. This latter supply of ammoniais mixed with hot air or gas, and in one method of workingis passed tlirou
