摘要： A process system is disclosed for the treatment of a waste sand material containing metal contaminants. The waste sand material is the product of sandblasting techniques used to remove paint. The metal contaminants generally include lead, copper, chromium, mercury and cadmium, among other heavy metals. The process particularly provides for the concentration of the lead contaminant in a waste sand that can be economically reclaimed or disposed in an environmentally safe manner. The process also produces a cleaned sand that contains only residual amounts of the metallic contaminants in environmentally acceptable levels. The process provides for the contacting of the waste sand material with a paint decomposer, attrition abrading this sand slurry, size separating the attrition abraded slurry to form a waste sand slurry and a cleaned sand, and removing a portion of the excess water content in the waste sand slurry.

摘要： The concentrations of residual heavy metal contaminants in the particulate material in a slurry produced in a particulate material washing process are monitored on-line and can be used to control the washing process. In alternative embodiments of the invention, x-rays, thermal neutrons or laser beams are directed at the slurry as it flows through a flow cell to induce emission of secondary x-rays, gamma rays or light, respectively, characteristic of the heavy metal contaminants and constituents representative of the solids contents of the slurry. These characteristic energies are measured and used to determine the concentration in ppm of the residual heavy metal contaminants in the particulate material within the slurry.

摘要： An apparatus for directly powering a unipolar electric motor with direct current (DC) power includes a control mechanism, and a solid oxide fuel cell (SOFC) having a fuel input and an oxidizer input. The control mechanism may control the fuel input and the oxidizer input. The fuel input may utilize a hydrocarbon fuel or, alternatively, an arbitrary mixture of hydrogen and carbon monoxide. The electric motor may have a field excitation current and the control mechanism may further control the field excitation current. Alternatively, an apparatus may power a vehicle, such as a ship or automobile, and may include an electric motor for powering the vehicle, a fuel cell for providing fuel cell power, a turbine-generator for providing turbine-generator power, and a control mechanism. The electric motor may include a motor power input. The fuel cell may include a fuel input, a fuel cell oxidizer input, a thermal exhaust output, and a fuel cell power output. The turbine-generator may include a compressor for pressurizing oxidizer, a generator for producing a generator power output, and a turbine for driving the compressor and the generator. The generator power output may supplement the fuel cell power output in order to produce power for the motor power input. The turbine may have a thermal exhaust input interconnected with the thermal exhaust output of the fuel cell. The compressor may have a compressor oxidizer input and an oxidizer output interconnected with the fuel cell oxidizer input. The control mechanism may control the fuel input, the compressor oxidizer input or the field excitation current.
