The EPA has identified indoor air pollution (IAP) as one of the most urgentenvironmental issues in the US. While there are many sources of IAP, the mostprevalent and difficult to address is secondhand cigarette smoke. Existingtechnologies are excellent at removing particulates, but are inadequate forremoval of VOCs. Existing VOC removal technologies suffer from 1) effectivenesson only certain c ...

Nitrogen oxide emissions from combustion processes reaction with hydrocarbons in the atmosphere are precursors to the formation of ozone. To reduce atmospheric ozone, nitrogen oxide emissions are being regulated. A new method for removing nitrogen oxides from combustion gas streams is proposed. The process system minimizes risks and hazards associated with the transport, storage and use of anhy ...

Energy and Environmental Research Corporation (EER) proposes to develop a highefficiency NOx control process that recycles NOx in gas turbine exhaust to theflame zone to be destroyed. This process uses a regenerable adsorbent in asimple thermal cycle with no additives or waste materials. Experimental studiesshow that NOx can be reversibly adsorbed on certain inorganic compounds. NOx isdesorbed ...

MCP Urethanes propose to synthesize a filter capable of removing low levels ofhazardous metal ions such as mercury, lead, and zinc from industrial wastestreams. The filter will function by adsorption and chelation and be selectivefor the hazardous metal ions over the alkali and alkaline earth metal salts. Thefilter will insert directly into the industrial sewer. When fully loaded, thefilter wil ...

In the chrome-electroplating industry, rinsing of finished products generatestoxic wastewater containing chromium metal. These waste-waters present asignificant disposal problem and a loss of valuable raw material in the form ofchromium, a predominantly imported metal. Coupled transport membranes are apotential method of separating and recovering the chromium, but their use hasbeen restricted du ...

This proposal covers the development of a hybrid Brayton cycle/ membraneseparation system for VOC control. The new system design offers significantcapital and operating cost savings compared to current membrane vapor systems andcould make membrane technology competitive with alternative processes in the feedflow range up to 2,000 scfm.In the Phase I program, the overall feasibility of the new des ...

U.S. industry generates large volumes of wastewater that contains suspendedparticles, emulsified liquids, dissolved macromolecules, and/or dissolved organiccompounds. Nanofiltration can produce dischargeable water from these streams.However, because current nanofiltration membranes are finely porous and onlymoderately hydrophilic, they are subject to fouling, particularly by particulatesand macro ...

Millions of gas fired residential and commercial water heaters are installed nationwide. Uncontrolled NOx emissions from these units are high, relative to industrial low NOx burner emissions. New low cost approaches to control NOx are needed, to limit emission from water heaters.

Non-attachment air quality regions will require the implementation of ultra-low-NOx boiler burner systems. Currently, only costly Selective Catalytic Reduction (SCR) systems can achieve 9 ppm NOx emissions. Alternative and inexpensive low NOx burners, that can meet the regulations without SCR, are urgently needed by the utilities industry. Altex Technologies Corporation has identified the Minim ...
