This project involves the development of a consumer aerosol dispenser that seeks to eliminate the volatile organic compound (VOC) solvents and hydrocarbon (HC) propellants used in many commercial sprays. The two distinguishing features of the dispenser are: (1) application of ligament-controlled effervescent atomization for producing very small droplets independent of the fluid viscosity, and (2) ...

Generally, it is accepted that for plastics recycling to be economically viable in the long term, recycled resins must be competitive with virgin resins. To compete with virgin material, new applications must be made available for recycled resins. Such applications will require that the recycled resin be of a high purity level. Thus, many processors are requiring ever-tightening contamination limi ...

Sandhill Industries, a woman-owned small business and manufacturer of glass wall and floor tile, has developed a process for manufacturing paving products made from 99 percent recycled soda-lime plate or container glass. The glass pavers are thinner, lighter, denser, stronger, and perform better in paving applications than brick or concrete. Furthermore, the manufacture of the glass pavers generat ...

COAL TAR IS A BY-PRODUCT OF THE COAL GASIFICATION PROCESS USED WIDELY BETWEEN 1820 AND 1950 TO PRODUCE A NATURAL GAS SUBSTITUTE. DURING THAT TIME, BILLIONS OF GALLONS OF TAR WERE PRODUCED AT MORE THAN 1500 GAS MANUFACTURING FACILITIESLOCATED THROUGHOUT THE U.S. A LARGE PORTION OF THIS WASTE TAR REMAINS IN STORAGE OR WAS DISPOSED OF BY INJECTION INTO SUBSURFACE SITES. COAL TAR IS A MIXTURE OF HYDRO ...

OPTRA, Inc., is proposing a low-resolution ( 15 nm) Fresnel sapphire split-prism spectrometer specifically tailored to the identification of molecular species present in the emissions from an engine source. The proposed approach will examine the 3-5.5 ¿m spectral region, allowing for the extraction of concentration information of CO2, CO, NO, HCs, and particulate matter. Sapphire was chosen bec ...

Mide Technology Corporation proposes to develop a fuel injection system for automotive combustion control. The design is composed of a fast-acting piezoelectric actuator to operate a fuel injection valve and emission sensors located in the exhaust, both used in concert with a rapid-learning control algorithm to reduce engine NOx, hydrocarbon (HC), and particulate emissions without sacrificing fuel ...

New regulations for drinking water treatment are leading to alternatives to chlorine disinfection. As a result, the use of ultraviolet (UV) light for disinfection is growing rapidly. The disinfection capability of commercial UV systems is limited by available mercury lamp technology. Phoenix Science & Technology's innovative Surface Discharge (SD) UV lamp is a promising candidate to both improve t ...

RECENT PROMISING DEVELOPMENTS IN THE PETROLEUM INDUSTRY "PROFILE MODIFICATION TECHNOLOGY" (PMT) WILL BE EVALUATED FOR THEIR APPLICATION TO LEAKING LANDFILL SITES. PROFILE FLOW MODIFICATION TREATMENTS ARE USED TO INCREASE FLOW RESISTANCE IN HIGH PERMEABILITY AREAS FAR (75 FEET TO AS MUCH AS 1000 FEET) FROM THE INJECTION WELLBORE. THESE TREATMENTS CAN WITHSTAND FORMATION PRESSURES AND TEMPERATURES U ...

OPERATING STRATEGIES HAVE BEEN DEVELOPED FOR BIOLOGICAL SEQUENCING BATCH REACTOR (SBR) TREATMENT OF BOTH MUNICIPAL WWASTE (I.E. LOW-STRENGTH WASTES) AND INDUSTRIAL WASTES (I.E.HIGH-STRENGTH WASTES CONTAINING DIFFICULT TO DEGRADE ORGANICS). SBR SYSTEMS SHOULD ALSO OFFER ADVANTAGES FOR BIOLOGICAL TREATMENT OF MIXED MUNCIPAL AND INDUSTRIAL WASTEWATERS THAT ARE RELATIVELY LOW STRENGTH, BUT CONTAIN INO ...
