This Phase I research is intended to evaluate the feasibility of manufacturing low-cost, acid-resistant sanitary sewer pipe from sulfur concrete. Sulfur is an abundant mineral recovered from coking, natural gas processing, and petroleum refining. Secondary recovery of sulfur, resulting from environmental regulation, produces more material than is needed by U.S. industry. The U.S. Bureau of Mines ...

A NOVEL EMISSION CONTROL PROCESS FOR CHLORINATED HYDROCARBONS PRODUCES NO TOXIC OR CORROSIVE SECONDARY GASES. CATALYTIC ADSORBENT MATERIALS WILL BE DEVELOPED TO DESTROY LOW CONCENTRATIONS OF CHLORINATED HYDROCARBON IN GASEOUS EFFLUENTS WITHOUT THE RELEASE OF HYDROCHLORIC ACID AND CHLORINE GAS. INSTEAD THE ADSORBENT WILL FIX THE CHLORINE ATOMS AS HARMLESS NONVOLATILE CHLORIDE SALT AT TEMPERATURES W ...

THE INSPECTION OF VERY LARGE CRUDE CARRIERS (VLCC) FOR STRUCTURAL RELIABILITY IS AN IMPORTANT ENVIRONMENTAL CONCERN. THESE LARGE VESSELS TRANSPORT CRUDE OIL IN SUCH QUANTITIES THAT THE CONSEQUENCE OF AN OIL SPILL DUE TO A BROKEN WELD ARE VERY SERIOUS. IMPROVED TECHNIQUES ARE NEEDED TO INSPECT VLCC TANKS FOR DEFECTS SUCH AS CRACKS IN SEAMS, CORROSION AND FAILED STRUCTURAL MEMBERS. THE COST OF INSPE ...

RADON-222 IN INDOOR AIR HAS BEEN IDENTIFIED AS A PERVASIVE POLLUTANT AND A SIGNIFICANT HEALTH THREAT. ARETE TECHNOLOGIES PROPOSES TO INVESTIGATE A MEMBRANE-BASED SYSTEMFOR MITIGATING THE INDOOR AIR POLLUTION PROBLEM TO WHICH WATERBORNE RADON GAS CAN CONTRIBUTE. THE SYSTEM, WHICH OPERATES AT WATER SUPPLY PRESSURE, AVOIDS THE PROBLEMS OF RADIOACTIVITY BUILDUP AND SPENT CARBON DISPOSAL ASSOCIATED WIT ...

BASIC BIO SYSTEMS, INC., PROPOSES TO INVESTIGATE A NOVEL APPROACH TO OIL SPILL CLEANUP UTILIZING A NATURAL, OAT-DERIVED DISPERSANT. PROTEINACEOUS OAT FRACTIONS DEVELOPED BY BASIC BIO SYSTEMS, INC. HAVE THE ABILITY TO ABSORB SEVERAL TIMES THEIR WEIGHT OF A WIDE RANGE OF COMPOUNDS, INCLUDING HYDROPHOBIC MATERIALS SUCH AS OILS. INADDITION, THESE FRACTIONS CAN FUNCTION AS EFFECTIVE EMULSIFIERS, FORMIN ...

ADDITION OF COSOLVENTS TO WATER INCREASES THE SOLUBILITY OF HYDROPHOBIC CONTAMINANTS BY SHIFTING THE ADSORPTION EQUILIBRIUM TO FAVOR HIGHER AQUEOUS PHASE CONCENTRATIONS. INCREASING THEIR WATER SOLUBILITY MAKES CONTAMINANTS MORE ACCESSIBLE FOR BIODEGRADATION. WHILE IT IS OFTEN SPECULATEDTHAT LOW RATES OR LACK OF BIODEGRADATION IS CAUSED BY LOW AQUEOUS SOLUBILITY, NO STUDIES HAVE BEEN PERFORMED TO D ...
