The ecological potential of a restored abandoned quarry

Jun 01, 2011 In most abandoned mines, the destruction of vegetation is the major factor that leads to the ecosystem degradation (Singh et al., 2004). Obviously, restoration of the vegetation is the key to improving the ecological environment and thereby drive the rehabilitation of the ecosystem, which in turn enhances regional productivity (Lu et al., 2006).

vegetation cover and the destruction of landscape, and forest ecosystems around quarries and mines [3]. It also refers to the dumping of waste materials from quarries on the surrounding areas, fragmentation of forest land, loss of top soil, nutrients and supportive micro-flora, deforestation, diminished green cover and loss of vegetation [4].

Wet Flue Gas Desulfurization with Lime/Limestone Slurry

The essential process stages of this wet desulphurisation method are: Absorbent preparation and dosing. Removal of SOx (HCl, HF) Dewatering and conditioning of the product. In this method, limestone (CaCO3) or quicklime (CaO) can be used as the absorbent. The selection of an additive which can be added dry or as a slurry is made on the basis of

WET FLUE GAS DESULFURIZATION WITH LIME/LIMESTONE

Separation of sulphur oxides (SOx) and other acidic components (HCl, HF) by injecting lime suspension (limestone or lime water) into the absorber. Semi-dry desulphurization Injection of lime slurry into the spray absorber to clean the gases mainly from SOx but also other acid components like HCl and HF.

Blending lime and iron waste to improve sorbents

Dec 01, 2012 Lime and iron waste were blended in various ratios and the resulting sorbents tested in two equipments namely; pH-stat apparatus simulating wet flue gas desulfurization (FGD) and fixed bed reactor for dry FGD, to investigate the effect of the blends in the FGD process. The best blend was found at a ratio of 1:2 (lime to iron waste) by mass.

Flue Gas Desulfurization by Limestone and Hydrated Lime

lime is used as sorbent material instead of limestone. It is known that, the hydrated lime possesses higher desulfurization capacity than limestone due to its higher solubility and higher alkalinity in slurry and better reactivity with SO2 at low temperature (Ma et al., 2000; Özyuğuran et al., 2006).

The term deep desulfurization refers to the removal of 90 to nearly 100% of the sulfur contained in the petroleum fraction. This corresponds to an average product sulfur level of 25 ppm in naphthas, 0.1 wt% in gas oils, and 0.3 wt% in residual fuel oils. These low sulfur contents are dictated by increasingly stringent government regulations.

Although the hydrodesulfurization of light and middle distillates such as gasoline, naphtha, kerosene, and gas oil is also evaluated, the emphasis here is on sulfur removal from the resid- ual fuel oil where there is a growing concern today because of air pollution.
