As wildfires are increasing in prevalence and intensity there is a need for miniaturized, lower cost, and easily portable air sensor systems that provide accurate information to air quality and public health managers, communities, and researchers, so that the public can be protected and timely decisions can be made. Fixed site measurement stations are large and expensive. More dense networks of sm ...

CURRENT AND FUTURE LEGISLATION WILL REQUIRE U.S. INDUSTRY TO TREAT MANY ORGANIC SOLVENT-CONTAINING AIR STREAMS NOW BEING DISCHARGED TO THE ATMOSPHERE. STREAMS OF THIS TYPE ARE PRODUCED BY PROCESSES SUCH AS PAINT REMOVAL AND METAL DEGREASING, AND IN PAINTING AND COATING OPERATIONS. MEMBRANE TECHNOLOGY AND RESEARCH (MTR) HAS DEVELOPED A MEMBRANE VAPOR RECOVERY PROCESS THAT IS ABLE TO REMOVE SOLVENT ...

Acidic metal-contaminated mine water impacts tens of thousands of miles of streams in the US. Treatment requires neutralization of acidity followed by precipitation and management of the metals. Conventional mine water treatment systems use lime (CaO) or caustic (NaOH) to generate acid-neutralizing alkalinity. The high cost of these conventional technologies has contributed to the bankruptcies of ...

The Need and Our Technology: Most wall systems built in the US emit carbon during production (embodied carbon). The building industry accounts for 39% of global CO2 emissions, with 11% of these emissions from the embodied carbon of materials due to sourcing, manufacturing, and implementation. Verdant Structural Engineers (VSE) will combat embodied carbon emissions and strengthen the structural ins ...

PARTICULATE EMISSIONS BY DIESEL ENGINES ARE A SERIOUS HEALTHHAZARD AND HAVE BEEN THE FOCUS OF RECENT EPA RULEMAKING RESTRICTING EMISSIONS BY LARGER DIESEL VEHICLE ENGINES. AVAILABLE TECHNOLOGY AND ECONOMIC CONSIDERATIONS HAVE RESTRICTED USEFUL DECISIONS ON HOW MUCH TO RESTRICT PERMIS SIBLE PARTICULATE EMISSION LEVELS. WILLIAM C. PFEFFERLE ASSOCIATES (WCP) HAS INVENTED A PROPRIETARY CATALYTICALLY- ...

WIDELY USED CHLORINATED HYDROCARBONS (CHCS) SUCH AS TRICHLOROETHYLENE, PERCHLOROETHYLENE AND METHYLENE CHLORIDE ARE RECOGNIZED AS CARCINOGENS AND MUTAGENS, AND CONTRIBUTE TO GLOBAL WARMING AND OZONE DEPLETION. THEREFORE, THERE IS AN INCREASING NEED FOR LOW COST AND EFFICIENT METHODS FOR THE CONTROL OF CHC EMISSIONS. CATALYTIC INCINERATION IS GENERALLY THE TECHNOLOGY OF CHOICE BECAUSE IT HAS LOW EN ...

Widespread implementation of chlorinated volatile organic compound (VOC) emissions control technologies is anticipated for manufacturing plants and remediation of historical groundwater and soil contamination. To facilitate compliance monitoring and to improve cost-effectiveness of control technologies, a reliable, continuous CVOC monitor is essential. Current CVOC instruments do not meet this g ...

A UNIQUE GAS TURBINE/VOC INCINERATION SYSTEM BASED ON CATALYTICALLY STABILIZED (CST) INCINERATION IS PROPOSED, OFFERING BOTH VERY LOW NET CONSTS AND ULTRA HIGH DESTRUCTIONOF ORGANICS IN ANY ORGANIC FUME OR AIR STREAM, INCLUDING THOSE LADEN WITH PARTICULATES (WHETHER ORGANIC, SUCH AS COTTON OR GRAIN DUSTS, OR INORGANIC SUBMICRON PARTICLES). THE SYSTEM WILL PROVIDE IMPROVED DISTRUCTION COMPARED TO A ...

THIS PROPOSAL PRESENTS A CONCEPT FOR A CHEMICAL MONITOR BASED ON DIFFERENTIAL CATALYTIC REACTIVITIES AND LARGE REACTION EXOTHERMICITIES. THE SIMPLICITY OF THE PROPOSED SENSOR CONCEPT PROMISES AN ECONOMIC AND RELIABLE MONITOR FOR IN-SITU MEASUREMENT OF A VARIETY OF GASES. IN THIS PROJECT, ENVIROCHEM, INC., WILL INVESTIGATE THE APPLICATION OF THIS CONCEPT FOR MEASURING AMMONIA IN FLUE GASES. A SENSI ...

There is growing concern about the particulate pollution emitted by outdoor wood-fired boilers (0WBs) and their related health effects. These systems are also referred to as outdoor wood-fired hydronic heaters or outdoor wood-fired furnaces. There are currently over 500,000 OWBs installed, primarily in the northern US. During the Phase I SBIR project, a catalytic combustor system that can be retro ...
