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 ...

The presence of per- and polyfluoroalkyl substances (PFAS) in the environment represents an emerging issue due to their stability, bioaccumulation potential, and risks to human and ecological well-being. There is a critical need to develop sampling methods for PFAS to assess risks and inform remedial investigations and feasibility studies (RI/FS) at locations where historical releases have elevate ...

Biomass heating/cooking stoves in developing countries do not efficiently cook food or heat houses, while consuming too much fuel and emitting pollution resulting in respiratory illnesses, premature death, and climate change. Affordable technologies found in 1.) EPA approved heating stoves, 2.) DOE funded cooking stoves, and 3.) TEG (thermoelectric generation) lighting devices, improve heating, co ...

Due to their exceptional properties, polyurethane coatings are used extensively in our society.Unfortunately, the socyanate-functional components used in the curing of polyurethanes are generally toxic. Thus, there is a need for polyurethane resins that can be cured without the use of isocyanate-functional components. In addition to enabling the production of polyurethane coatings that are free ...

Nutrient pollution caused by excess nitrogen and phosphorus in the water is a costly and challenging environmental problem with widespread potential for negative health and ecological effects. The proposed solution to this problem is the capture of ammonium, urea, nitrate and phosphate on low-cost biodegradable sorbent pellets that upon saturation, with the nutrients can be employed directly as sl ...

Cellulose insulation is a well-established and $400M growing market. It is recognized for superior thermal insulating performance, its safety and its environmental benefits. UltraCell’s proprietary technology addresses two major issues facing the industry today: the decline in availability of newsprint as its primary feedstock and changes in OSHA labeling requirements scheduled for 2015. UltraC ...

Solvents are a valuable processing tool in the chemical and related industries. Solvent are used to enhance mass transfer, heat transfer and in most cases are a processing aid and eventually are not used in the final product but to enhance the fabrication of the final product. While solvents are very valuable, they also cause a significant problem with their volatility and associated emissions. ...

This Phase I Small Business Innovation Research Project develops methods of recycling rare earth alloys from used nickel metal hydride batteries. Alloys of rare earth metal, nickel and other metals provide functional hydride storage materials that are critical to the operation of nickel metal hydride batteries and their applications. The current fleet of hybrid electric vehicles relies upon nick ...

The U.S. EPA Stage 2 Disinfectants and Disinfection Byproducts Rule (S2DDBR) requires potable water utilities to maintain total trihalomethane (TTHM) concentrations below 80µg/L at all locations within distribution systems beginning in 2012 due to adverse health-effect risks. Air stripping effectively volatilizes TTHMs due to their low Henry’s law constants. However, commercially available ai ...

There continues to be a need for low cost production and shipment of fuel-grade ethanol from agricultural sources. Ethanol from agricultural sources has many advantages including developing fuel independence and significantly reducing greenhouse gases. Also, bio-ethanol has significant value as an oxygenated and octane improver. Although ethanol from agricultural sources has many advantages, th ...
