Black Carbon Capture Technology for Reducing Effects of Climate Change Using 1d3d Mechanical Cyclone

Annual mean concentrations of black carbon in urban background stations and roadside locations are 1.0–2.0µg/m ³ and 1.4–5.1µg/m ³ respectively. Normal city air carries about 1370µg/m ³ of suspended matter which is the practical limit and ambient quality standard for industrial gas cleaning. Black carbon concentrations from suspended matter bring about the greenhouse effect which leads to climate change. Computational Fluid Dynamics (CFD) involving model design, meshing, CFD simulation and postprocessing was used to develop 1D3D mechanical cyclones with 100% particle collection efficiency for black carbon. A geometrical swirl number was used to adopt the black carbon capture mechanical cyclone. This mechanical cyclone was deployed to exhaust chambers and rooftops of buildings in the open air which are; anthropogenic and natural sources of black carbon emission respectively. Black carbon with particle size of 0.2–10µm and other greenhouse particulate emissions with particle size of 0.2µm and above were captured by the mechanical cyclone while clean air was discharged into the atmosphere. This helped in reducing the effects of climate change. Validation of the obtained result was carried out while analytical confirmation of the result showed that; 0.943µg/m ³ of particulates were suspended in air after black carbon capture. When compared to 1.0–2.0µg/m ³ and 1.4–5.1µg/m ³ which are the annual mean concentration of black carbon in urban background stations and roadside locations respectively, as well as 1370µg/m ³ which is the practical limit and ambient quality standard for normal city air, it is clear that this research has been able to achieve its objective.
