Definitions
- the object of this invention is to turn to profitable account the several chemical substances which are now wasted generally, to the detriment of the localities where gasworks are situated, by being allowed to pass into the sewers or waters surrounding such places.
- My invention consists in the process of extracting and utilizing the above-mentioned impurities contained in crude gas after they have been separated therefrom by the action of the material I employ for that purpose, and restoring such purifying material after it has become charged to its full extent with such impurities, all as more fully hereinafter described. Before proceeding to describe my process of restoring and utilizing, I will first describe the purifying process by which the material to be restored is produced.
- the manner in which the material (hereinafter more fully described) is made use of in the purifying of gas is as follows: In the ordinary purifiers, consisting of iron boxes of ahyshape, with trays or screens on which the purifying material is placed, and through which the gas is passed, I place my material to the depth of five or six inches, or more, in the same manner as lime or oxide of iron are at present used. The impure gas from the condensers is then passed into the bottom of such ordinary purifiers, and passing upward by to.
- I use ggeen copperas (sulphate of iron) either crystallize or an y us, with or without the admixture of sawdust, or other kindred material, to render the sulphate of iron light 'and porous, to allow the free passage of gas through the substance in the purifiers.
- I may use the residuum from the manufacture-of sulphur from what is commercially termed spent oxide of iron that is to say, oxide of iron, iron-ore, bog-ore, or any other suitable compound of iron, which has been used for the purification of gas from sulphureted hydrogen, until it is so fully charged with sulphur as to be of no further use for purifying purposes.
- Sul hate of manganese may also be employed in similar manm described for sulphate of iron; as also the residuum from oxide of manganese when charged with sulphur, and treated in a similar manner as described for spent oxide of iron.
- This material when placed in purifiers, as previously described, and coming in contact with gas containing ammonia and sulphureted hydrogen, causes a chemical action to take place, such ammonia being retained by the sulphuric acid of the material, thereby forming sulphate of ammonia with the precipitation of the iron of the material, which iron decomposes the sulphureted hydrogen by combining with the sulphur therein contained. This action is constant until thorough saturation of the material is accomplished, when it is removed to be replaced by fresh material. This saturated material will then contain about thirty-three per cent. of sulphate of ammonia.
- the saturated material can be subjected to the action of water,whereby the sulphate of ammonia therein contained can be extracted in solution, and the salt produced by crystallization or evaporation of the said solution, and the remaining mixtures of iron, sulphur, and other substances are then subjected to heat without access of air in vessels or retorts, and proceeded with as before stated for the reformation of sulphate of iron for subsequent operations.
