The flue gases of combustion-type power plants contain small, respirable ash andfume particles which originate from the inorganic species in the fuel. Coalburning power plants, for example, have a notorious reputation for spewing outflue gas particles originating from the mineral mater in the coal. These fluegas particles (10 microns in diameter) must be characterized for two reasons:1) to deter ...

The problem addressed in this project is the need to monitor oxides of nitrogen(NOx, ie NO and NO2) levels in the combustion gases of stationary sources suchas power plants in order to facilitate on-line control of the scrubbers that willbe used to remove those pollutants. Since the measurements are in the parts permillion range, simpler and less expensive instruments than those currently used,su ...

The development of an instrument for continuously monitoring SO2 levels in fluegas is proposed. The SO2 will be detected by means of an electrochemical sensorcell, which operates in a three-electrode potentiostatic mode. The proposedinnovation is develop-ment of an advance sensor cell which uses a high-temperature solid polymer eleobjectives of the proposed program are 1) identification of poten ...

An efficient method for directly removing chromate and metals such as nickel,zinc, cadmium, mercury, cobalt, chromium(III), lead in two separate stages isproposed. The highly capacity sorbents could be regenerated, recovering thechromate and other metals separately. The regeneration is expected to beefficient and is simply based on changing the pH from one extreme to another.Bench scale characte ...

New ideas are presented on the covalent attachment of chelating functionalitiesto novel, highly hydrophilic sobent material, which can then complex heavy metalions irreversibly and is targeted toward lead removal. The efficient removal ofother heavy metals, such as cadmium, chromium, mercury, zinc, nickel, cobalt, andcooper are anticipated. The covalent attached ligands are expected to be stable ...

Technology is needed for control of emissions of volatile organic compounds(VOC's) and toxic air pollutants (TAP's) from stationary sources. A particularneed exists for emissions control of industrial processes, where diluteconcentrations of VOC's are present in high flows of offgas which may alsocontain submicron particles.The proposed research project is to establish the technical and economicf ...

The project objectives are to develop and evaluate a generic methodology foremission control of a wide variety of air toxic particulate using a revolutionarybreakthrough in filtration technology based on the recently developed BoundaryLayer Momentum Transfer (BLTM) concept. This novel filter is designed to augmentand substantially improve separate conventional toxic treatment/ reclamationmethodol ...

Indoor air in work places, automobiles, recreation settings and homes is one ofthe major sources of direct human exposure to particulates, chemicals and diseasecausing bacteria. Recent estimates suggest that more than 98% of theseparticulate pollutants are very small (less than 1 ) and, therefore, cannot beeffectively filtered by exiting filters. These particulates are also know to becarriers o ...
