Flotation Agents Impact on the Carbon Capture from Ash of Coal-steam Plants

Abstract

Nature and consumption of foam-blowing agents and different collectors effects on carbon capture from ash were studied. The dependance of the foam-blowing agents consumption and the of flotation efficiency index was traced. The SAS-2 modifying agent impact on chemicals consumption was demonstrated. It was found that the floatability of a number of collectors among investigated petroleum products, in the case of preliminary application of the SAS-2 modifying agent, is determined by its molecular composition and declined as follows: kerosene>(mixture: vacuum gas oil + kerosene)> motor alkylate> heavy polymer-distillate. It was demonstrated that the use of required modifying agent at feeding before collector application improves the flotation efficiency and reduces the collector consumption.
