| 7045065 | Method of removing radioactive antimony from waste streams A method and related apparatus for monitoring and eliminating gas build-up in an anion exchange column comprised of an anion exchange material placed within a vessel and a liquid layer comprising water contaminated by at least antimony passing through said vessel, w... | 05/16/2006 |
| 6334337 | Air bubbler to increase glass production rate In a glass melter, a precious metal insert is used to protect a gas bubbler from corrosion at the orifice of the bubbler through which gas is injected into the melt. The use of a precious refractory metal insert at the bubbler orifice prevents the attack ... | 01/01/2002 |
| 5678236 | Method and apparatus for eliminating volatiles or airborne entrainments when vitrifying radioactive and/or hazardous waste In this invention radioactive or hazardous containing materials are vitrified in a melter having two or more chambers. Glass feed materials are added to the primary chamber of the melter and they are heated to a molten glass which is then transported to o... | 10/14/1997 |
| 5430236 | Method for vitrifying ash By changing the additives to an off-gas system in an incinerator bag house, by replacing part of a normally added calcium compound with a sodium compound, one can reduce the amount of sodium compound needed for a combined off-gas from incineration and gla... | 07/04/1995 |
| 5405590 | Off-gas scrubber system An off-gas quencher and solid recovery scrubber unit includes a wet flue gas scrubber which has the dual responsibilities of lowering the temperature of the inlet hot gas entering through the scrubber and trapping contaminants from the gas stream into the... | 04/11/1995 |
| 5340372 | Process for vitrifying asbestos containing waste, infectious waste, toxic materials and radioactive waste Material, such as, for example, sealed double bags of asbestos containing waste or ash from infectious waste or toxic material or radioactive waste, is transferred into a glass melt of a furnace. Gas bubbles released into the melt form a gas curtain which... | 08/23/1994 |
| 5188649 | Process for vitrifying asbestos containing waste, infectious waste, toxic materials and radioactive waste Material, such as, for example, sealed double bags of asbestos containing waste or ash from infectious waste or toxic material or radioactive waste, is transferred into a glass melt of a furnace. Gas bubbles released into the melt form a gas curtain which... | 02/23/1993 |
| 4902426 | Ion exchange compositions The present invention comprises a process for separating rare earth ions or actinide ions or mixtures thereof in solution by passing the solution through an ion exchange material to separate the rare earths or actinides or mixtures thereof. The ion exchan... | 02/20/1990 |
| 4876232 | Supported heteropolycyclic compounds in the separation and removal of late transition metals Compositions comprising carbon-based supports and containing heteropolycyclic compounds such as bipyridyl, phenanthroline or derivatives thereof are used in separation of dissolved late transition metals such as Fe, Co, Ni and Cu from solutions, in partic... | 10/24/1989 |
