To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

This EPA SBIR Phase I Research and Development proposal will demonstrate feasibility of reduction in halogenated flame retardant use in polyisocyanurate foams prepared from lignincontent rPET polyols. The study will show whether or not the lignin rPET polyol formulations meet ASTM flame retardancy standards and thus reduce or eliminate the need for halogenated fire retardants (HFRs) in spray foams ...

The goal of this project is the formulation a rigid, insulating, low-density wood composite, with physical and thermal properties comparable to fossil fuel derived foams. _x000D_ _x000D_ To achieve energy conservation standards mandated by certification agencies such as Passive House and LEED, high performance buildings require multiple shells of insulation – an inner shell that contains electri ...

The In Process Control for L-PBF (IPCL) program leverages and in process inspection method recently developed and successfully demonstrated for NASA. This Layer Topographic Map or LTM method measures the surface if every melt layer using a commercial laser profilometer. LTM software detects, locates and identifies flawed regions within a layer for every layer in the part. It does so for several co ...

TECHNICAL ABSTRACT: The objective of this project is to research the technical feasibility of designing a software tool “Permit Wizard” that will automate the process for aquamarine permit application submittal, review, approval/disapproval and issue (including collection of fees). Aquaculture producers are currently faced with slow, complex, and often confusing permitting processes that must ...

Major improvements in process control, compliance monitoring, and environmental decisionmaking could be made if more accurate, less costly, more rugged techniques were available for continuous monitoring of multiple gas phase pollutants. As part of the solution, Fourier Transform Infrared (FT-IR) spectroscopy is emerging as a promising Field Analytical Method (FAM) for multiple gas monitoring. H ...

Ozone treatment of wastewater to destroy organic contaminants prior to discharge into the environment is an extremely effective advanced oxidation technology. To date the use of this powerful technology has been limited in part by the relatively high capital costs of an efficient ozone to water, gas-liquid, mass transfer system. Existing ozone injection devices must overcome the inherently low m ...

Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean burn limit (beyond which combustion is poor) restricts further emission reductions, the use of oxyg ...

This Phase I project involves the development of a phytoremediation technology for the cleanup of TNT-contaminated soils at the Volunteer Army Ammunition Plant (VAAP) in Chattanooga, TN (an upland site). Phytoremediation, the use of plants to clean up contaminated environments, has a great potential for soils contaminated with TNT. Recent discoveries suggest that intrinsic plant enzymes (not micr ...

The need to reduce ozone in urban areas has led to increased regulation for the control of the ozone precursors¿namely volatile organic compounds (VOCs) and nitrogen oxides. However, current control technologies, such as incineration and adsorption on solids, have a number of disadvantages for the wide range of VOC-emitting industries. Catalysts provide an alternative control strategy. Recent ...
