Subseabed disposal of radioactive waste: effects of consolidational fluid flow
Environmental Geology, 1996Subseabed disposal of radioactive waste applies a multiple-barrier concept with the sediment being the most important barrier for preventing a release of nuclides into the biosphere. While many investigations have been carried out to analyze the risk potential in this type of disposal, the effects of sediment consolidation and associated fluid flow ...

Useful Recycling and Safe Disposal Technology of Waste Oil Based Drilling Fluids and Its Application
International Petroleum Technology Conference, 2013Abstract Waste oil-based drilling fluids are hazardous wastes containing oil, heavy-metal and organic pollutants. However, the common treatment methods at home and abroad these methods not only waste many useful resources (because the oil is discarded rather than recovered) but also increase the pro-environment cost

Fluid Bed Catalytic Oxidation: An Underdeveloped Hazardous Waste Disposal Technology
Hazardous Waste, 1984ABSTRACT Fluid bed incinerators have been used to dispose of a wide variety of hazardous wastes including refinery waste streams, surplus explosives, PCB-contaminated transformer oil and oxychlorination process wastes. Both inert and catalytic solids have been employed separately and in mixed beds or sequential reactors.

Abstract The traditional methods of treating and disposing waste drilling fluid are encountering severe challenges with the tightening of environmental regulations in China. Commonly used chemical destabilization technology needs to be improved, and treating processes are required to be optimized and updated.

The metal working industries generate different kinds of waste waters as a result of processing metal parts/products, machinery, and other associated activities as well. The performing operations may have two types of activities: (a) manufacturing, and (b) rebuilding or maintenance. Actually, coolants are important component of metal working operations

Geochimica et Cosmochimica Acta, 2011
Abstract Diffusion coefficients for oxygen and hydrogen were determined from a series of natural uraninite–H 2 O experiments between 50 and 700 °C. Under hydrous conditions there are two diffusion mechanisms: (1) an initial extremely fast-path diffusion mechanism that overprinted the oxygen isotopic composition of the entire crystals regardless of ...

Terrain, Land Use and Waste Drilling Fluid Disposal Problems, Arctic Canada
ARCTIC, 1980A survey of over 60 abandoned wellsites in the Mackenzie Delta, the Arctic Islands and the interior Yukon Territory indicated that approximately 25% of the sites experienced terrain problems related either directly or indirectly to sumps and/or the containment of waste drilling fluids.

SPE International Conference on Health, Safety, and Environment in Oil and Gas Exploration and Production, 1998
Abstract During the next decade and beyond, a large number of wells will be drilled in Eastern Venezuela in order to produce very heavy oil. Because of both the nature of the reservoir and the length of the horizontal section, water based drilling fluids will become contaminated with anywhere from 3–20% crude oil during the drilling ...

26th Joint Propulsion Conference, 1990
The results are reported of a study of various methods for propulsively disposing of waste gases. The options considered include hydrazine waste gas injection, resistojets, and eutectic salt phase change heat beds. An overview is given of the waste gas disposal system and how hydrozine waste gas injector thruster is implemented within it.
