Exhaust Gases Purification of Sintering Furnaces Using Under-Sludge Water as a Gas Cleaning Solution

It is proposed to introduce an additional stage of "wet" cleaning of waste gases of caking at RUSAL Achinsk. For experimental industrial research, the work used a multi-vortex scrubber, in which the gas is cleaned in a dispersed water-air layer, formed by the flow of gases from the bottom up through the dispersing lattice. As an absorbent irrigation solution, it is proposed to use pre-heated up to 50 degrees Celsius water (PSH), containing an average of 8.98 g/dm3 and 16.74 g/dm3 of caustic and total alkaline, respectively. The efficiency of gas dust-cleaning was assessed depending on the consumption of PSH (0.2–1.2 l/m3 of gas at feed speeds of 0.2 hp and 0.4 hp), as well as the use of two schemes of its supply (flow and recycling).

Sulfur Gas Production in Ukraine (Review)

The state of sulfur gas production in Ukraine has been examined. The major producers and consumers of sulfur, as well as available technologies for gases purification from hydrogen sulfide have been characterized. The necessity of applying new methods of gas cleaning from hydrogen sulfide to form sulfur of special grades has been grounded. The advantages of quinhydrone cleaning method to form fine sulfur have been shown.
