    摘要: A process for the treatment of ground, spent potlinings generated during the production of metallic aluminum to reduce cyanide content to environmentally nonhazardous levels. Potlinings are ground or otherwise suitably reduced in size to a particle size of not greater than about 2 inches in any dimension and roasted in a stream of air or nitrogen at a temperature between about 500.degree. F. and 1400.degree. F. Roasting for an appropriate time-temperature interval reduces cyanide content to desired levels without combustion of a major portion of carbonaceous material, resulting in an end product rich in carbon and fluorine which may be salable because of this content.

    摘要: A conveyor flight for a conveyor assembly has an overlayment of a non-elastomeric flexible member on its front or loadbearing surface, which flexible member has a memory such that it recovers to its unloaded reference condition, thus assisting in discharge through an underlying chute or port of the materials transported by the conveyor and avoiding recycling material through the conveyor assembly. The flexible member recovery dislodges adherent material, such as compactible earth, from the conveyor flights. A cleaner assembly may optionally be provided downstream of the discharge port to insert a cleaner blade in proximity to the conveyor flight front surface to dislodge any particularly adherent residual materials that might still be attached to the front surface of the flexible member.

    摘要: A system and method are provided for growing microalgae in cold climate areas. The system includes an expanding Plug Flow Reactor with a plurality of ponds used to grow algae by mixing a culture fluid with a nutrient. To minimize the loss of heat due to environmental factors, the expanding Plug Flow Reactor is covered with a translucent, light-transmitting cover and is lined with an insulation liner. In addition, an underground sump and pump are provided and connected to the expanding Plug Flow Reactor. The sump is provided to store the algae at night when ambient air temperature is at its coldest. An adjacent power plant provides: (1) heat byproducts to warm the culture and (2) CO2 for use as a source of carbon in photosynthesis.

    摘要: A system and method for treating feedstocks containing solids, sludges or slurries that contain organics includes introducing the feedstock into a desorption chamber. In the desorption chamber, the temperature and pressure of the feedstock are elevated to volatilize a portion of the feedstock and thereby separate the feedstock into a volatile portion containing organics and a residue portion. Steam, water or oxidants can be injected into the desorption chamber to aid in the volatilization process. From the desorption chamber, the volatile portion of the feedstock is transferred to a reactor for hydrothermal treatment to oxidize or reform the organics in the volatile portion. In the hydrothermal reactor, the volatile portion may be reacted with excess oxidant and auxiliary fuel at a temperature between approximately 1000° F. and approximately 1800° F. and a pressure of between approximately 20 atmospheres and approximately 200 atmospheres.
