Desulfurization of High-Sulfur Lignites (Çan, Çanakkale-Turkey) by the Meyers Method
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
The uses of high-sulfur coals in burning processes are limited because of environmental pollution. In the world, the reserves of high quality coal are decreasing as well as Turkey where coal reserves are mainly lignite and almost 60% of the known reserves contain high sulfur coals therefore it is important to evaluate the low-quality lignites. Most of the produced lignite is utilized at the coal power stations where low-sulfur content is required. The polluting gases containing sulfur dioxide (SO2) after burning of low quality coals are the main reason for air pollution, acid rain and some respiratory systems diseases. For instance, a typical un-controlled coal plant emits 14.000 tons of SO2 per year. In this study, the Meyers (Fe3- salts) method was applied to Çan lignite with high sulfur content. In the first stage, the leaching experiments using Fe3- salts were carried out following Yates experimental design. The effects of particle size, temperature, time and Fe(NO3).9H2O concentration were investigated for the removal of sulfur. Later, optimization tests were applied taking into consideration effective parameter. Optimum conditions were 0.5 M of Fe3- salts concentration, 70 oC temperature, d100 = 75 µm particle size and 30 minutes of reaction time.
