Hazardous Waste Disposal by Supercritical Fluids

Separation Science and Technology, 1997
In the presence of water or carbon dioxide in the supercritical state, organic materials can be oxidized by oxygen practically completely within seconds. The report contains descriptions of test rigs and experimental findings. Additional R&D work is necessary for technical-scale application in cleaning organically polluted liquid effluents.

Durability of Zirconolite in Hydrothermal Fluids: Implications for Nuclear Waste Disposal

MRS Proceedings, 2000
ABSTRACTSynthetic zirconolite (CaZrTi2O7) doped with rare earth elements (REEs) and Hf has been subjected to corrosion tests in a closed system at elevated temperature and pressure in fluids with various compositions. Together with previous studies, the results indicate only a very weak corrosion below 250°C at a pressure of 50 MPa.

Offshore Disposal of Oil-Based Drilling-Fluid Wastes An Environmentally Acceptable Solution

SPE Drilling & Completion, 1993
Summary Oily cuttings and waste fluid are byproducts of oil-based drilling muds. In such difficult drilling environments as the Gulf of Mexico, where oil-based fluids often are preferred, personnel safety, environmental, and economic concerns are exacerbated by the necessity to transport these cuttings and fluids to shore for disposal ...

Oxidation of Organic Compounds in Supercritical Fluid Conditions During Disposal of Industrial Waste Waters of Nizhnekamskneftekhim PJSC and Kazanorgsintez PJSC

Ecology and Industry of Russia, 2023
The study performed on the supercritical aqueous oxidation of organic compounds in the water runoff of Nizhnekamskneftekhim PJSC, which was formed at the stage of epoxidation of propylene with ethylbenzene hydroperoxide during the joint production of propylene and styrene oxide, as well as run-off at PJSC "Kazanorginsez", when obtaining phenol and ...

Numerical Model of Fluid Flow through Heterogeneous Rock for High Level Radioactive Waste Disposal

AIP Conference Proceedings, 2007
An international consensus has emerged that deep geological disposal on land is one of the most appropriate means for high level radioactive wastes (HLW). The fluid transport is slow and radioactive elements are dangerous, so it's impossible to experiment over thousands of years. Instead, numerical model in such natural barrier as fractured underground

The Use of Biotreatment Technology to Dispose of Offshore Drilling Waste Oily Fluids

Advanced Materials Research, 2012
Disposing of oil-based drilling fluid with biotreatment technology has many advantages: it is only 30-50% of the expense of conventional chemical or physical processing technologies, has a low impact on the environment, with no secondary pollution, and utilizes local control and entails simple operations.

Recycling and Final Disposal of Waste Generated While Mixing Drilling and Completion Fluids

Proceedings of Latin American & Caribbean Petroleum Engineering Conference, 2007
Abstract As the emphasis on safety and efficiency increases in the oil industry, there has been a corresponding improvement in the quality of packaging for chemical products. Examples of higher standards include plastic shrink-wrap covers, better-designed pallets, and fewer sacks loaded per pallet.

Subseabed disposal of radioactive waste: effects of consolidational fluid flow

Environmental Geology, 1996
Subseabed 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 ...

Fluid Bed Catalytic Oxidation: An Underdeveloped Hazardous Waste Disposal Technology

Hazardous Waste, 1984
ABSTRACT 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.
