The article deals with the effect of potassium sulfates on setting behavior cement pastes. It has been established that main elements (Ca, Si, Al) are distributed in composition clinker minerals, while K and S atoms concentrated locally pores formation arcanite. is shown interaction K2SO4 CaSO42H2O followed by syngenite K2Ca(SO4)2H2O causes destructive phenomena

This paper describes a lab-scale simulated scrubber that was designed and built in the laboratory at Western Kentucky University’s Institute for Combustion Science and Environmental Technology. A series of tests on slurries of CaO, CaSO3, CaSO4/CaSO3 and Na2SO3 were carried out to simulate recirculating slurries in different oxidation modes. Elemental mercury (Hg) re-emission was replicated thr...

Sulfate scale deposition (BaSO4, CaSO4, and SrSO4) is a common problem in oilfield operations around the world, which causes significant formation damage during production and injection activities. This paper presents the results of an experimental study on the permeability reduction of porous media due to sulfate scale deposition. A set of experiments were cond...
