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.

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.

Microwave Drying of Drilled Cuttings in the Context of Waste Disposal and Drilling Fluid Recovery

Energy Technology, 2014
AbstractThe use of drilling fluids in oil drilling process generates solid–liquid mixtures that must be separated. One of the aims of this process is compliance with environmental laws regarding to disposal of waste from drilling activities. The present study aims to investigate the microwave drying of contaminated drilled cuttings.

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 ...

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.

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
