Risk assessment for hazardous waste disposal in abandoned mines
A significant technological challenge is the search for appropriate disposal of hazardous waste, It is evident that technologies that are simple, practical and economical for use should be developed, and they should both safeguard public health and reduce environmental pollution. Temporal disposal on the ground surface is a common approach in many European countries, a technique that could cont...
متن کاملHazardous Waste Disposal by Thermal Oxidation
Ideally, the flue gas resulting from high-temperature oxidation of hydrocarbons (HC) contains CO 2 , H 2 O, N 2 , O 2 and some acceptable levels of oxides of nitrogen (NOx) and oxides of sulfur (SOx). In reality, the flue gas from a combustion process contains CO 2 , H 2 O, N 2 , O 2 and some concentration of carbon monoxide (CO), unburned hydrocarbons (UHC), NOx and SOx .
متن کاملHazardous Waste Disposal: A Waste-Fuel Blending Approach
The disposal of hazardous wastes creates major economic and environmental problems for both developed and developing nations. One productive use of hazardous wastes is to blend them into fuel, which mitigates damage to the environment by recycling waste into fuel and reducing fossil-fuel consumption. Operations personnel face a daunting task of efficiently blending hazardous waste into fuel, wh...
متن کاملEvaluation of Aquifer Contamination from Salt Water Disposal Wells
In the United States an estimated 140,000 Class II wells for salt water disposal and enhanced hydrocarbon recovery are presently injecting some 30 million barrels of brine per day into subsurface formations. While no systematic survey has documented the extent of shallow ground water contamination from these disposal practices, it is recognized as a major potential pollution source in leading h...
متن کاملAmbipolar Tunneling in Near-surface Quantum Wells
We study the photoluminescence from a near-surface quantum well in the regime of ambipolar tunneling to the surface states. Under steady-state excitation an electric field develops self-consistently due to the condition of equal tunneling currents for electrons and holes. The field induces a Stark shift of the photolumi-nescence signal which compares well with experimental data from near-surfac...
