Varying ratios of industrial byproduct of flue gas desulfurization gypsum and recycled polyethylene were used to prepare composite matrices in order to develop an eco-friendly material. Small ratios of maleic anhydride grafted polyethylene were used as a compatibilizer. Surface morphologies and microstructures were examined by scanning electron microscopy images. Thermal behavior of the prepared composite materials was then investigated through thermogravimetry techniques. Hardness and tensile strength of the composite were evaluated through variations made to the contribution of individual components. The resulting composites exhibit increasing melt flow rate values, while hardness decreases with increasing maleic anhydride grafted polyethylene ratios. Amount of torque required to blend mixture also increases with maleic anhydride grafted polyethylene content.

And Performance

The oily sludge-based adsorbents for flue gas desulfurization were prepared by pyrolysis. Based on benzene adsorptivity, the conditions of pyrolysis process were optimized. The optimum prepared conditions of adsorbent material were in nitrogen atmosphere and 550°C, 4h, 10°C/min for the pyrolysis temperature, pyrolysis time and heating rate, respectively. In this case, the maximum benzene adsorbability was 60.12mg/g. Moreover, the main influencing factor was pyrolysis temperature, secondly was pyrolysis time and finally was heating rate. The sludge-based adsorbents were appropriate for flue gas desulfurization. The sulfur capacity of adsorbents via a flue gas desulfurization test after subsequent processing was about 3% and breakthrough time could keep to 109 min.

Flue Gas Desulphurization

Flue gas desulfurization (FGD) is one of the most effective techniques to control the emission of SO2 from the combustion of coal. The by-products of FGD may occupy much land and cause the second pollution. The resourceable technology of FGD changes SO2 from flue gas to sulfur-containing by-product, by which it is possible to solve the problem of desulfurization by-product treatment. This paper reviews the recent development of resurceable technology of FGD with special reference to removal of SO2 from flue gas.
