Developments in on-site spent solvent recovery have implications for reducedenvironmental pollution in the dry cleaning, furniture and paint manufacturingindustries as well as in a range of commercial services. Effluents from solventrecovery operations include fugitive emissions, vent stack gases and water/solvent mixtures. At present, the scale of solvent-recovery operations incertain industrie ...

The use of multi-component waste products provides an opportunity to produce aroofing material with an excellent balance of cost and properties. Simulatedslate tiles comprised of fly ash, other reinforcing filler, and thermoset hybridresin have been modelled. Based on initial market reactions to preliminary cost,physical properties data, and appearance, this application appears promising.Ecomat ...

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 ...

Incineration of Municipal Solid Wastes (MSW) often results in the emission oftoxic heavy metals, such as lead and cadmium. Previous work has demonstrated theability of some aluminosilicates sorbents, including common coal-borne minerals,to capture lead and cadmium vapors and, thereby, prevent their emission. Leadand cadmium capture by such sorbents have been shown to be non-leachable. PSITechno ...
