Process of sulfur removal
Webb29 juli 2014 · The intent of the process was to oxidize sulfide (S=) and hydrosulfide (HS-) ions to elemental sulfur by the reduction of the ferric (Fe+3) iron to ferrous (Fe+2) iron, and the subsequent reoxidation of the ferrous ions to ferric ions by contact with air. The chemistry of all chelated iron processes is summarized as follows with (l) and (v ... Webbcoal was treated by solvent extraction about 80% of the organic sulphur was removed. It was suggested that successive sequential extraction of coal might significantly improve the desulphurization efficiency of solvent extraction [2]. The effective removal of the thiophenic sulphur in petcoke is not, however, likely with simple solvent extraction.
Process of sulfur removal
Did you know?
WebbThe principle of desulphurization is to transfer the sulfur dissolved in the liquid steel to a CaO-rich slag phase. This process is typically carried out in a ladle furnace (LF). For this process to be successful, two conditions need to be fulfilled: The slag must be fully liquid (liquid fraction > 0.9). This is required for kinetic reasons. Webb28 apr. 2015 · iii. Sulfur removal to 10 ppm and lower (from >1000 ppm feed sulfur in one step!) If your goal is to meet a 30 ppm average product sulfur, our technology can help you achieve this. However, the S ZorbTM SRT process can also help you plan for the future, and for most gasoline feeds, our process can achieve product sulfur levels less then 10 ppm.

Webb30 juli 2016 · Process of desulphurization. Primarily, there are two options available for the removal of sulphur from the liquid steel. These are (i) by means of metal-slag reaction, where the top slag is mixed intensively with the liquid steel, and (ii) by injection of metallic calcium (Ca) into liquid steel, where a precipitation of sulphides occurs.
