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 ...

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 ...

THE ABANDONED BERKELEY PIT COPPER MINE SITE IN BUTTE, MONTANA, IS A MAJOR COMPONENT OF THE BUTTE SILVERBOW CREEK SUPERFUND SITE. IT CONSISTS OF SEVERAL BILLION GALLONS OF ACID (PH 2-3) MINE DRAINAGE THAT IS CONTAMINATED WITH TOXIC LEVELS OF A VARIETY OF HEAVY METALS, ARSENIC, AND SULFURIC ACID. THE FLOW OF CONTAMINATED WATER INTO THE PIT IS ABOUT 7 MILLION GALLONS PER DAY. CHROMATOCHEM, INC., AND ...

RESEARCH WILL BE CONDUCTED BY HICHEM CORPORATION, TO DEVELOP A NEW TECHNOLOGY FOR PYROLYSIS OF SCRAP TIRES. DISPOSAL OF USED TIRES IS A BIG PROBLEM IN THE WORLD, ESPECIALLY USA, SINCE MORE THAN 2.5 MILLION TIRES ARE DISCARDED EACH YEAR. MOST OF THESE TIRES ARE DISPOSED IN LANDFILLS. PYROLYSIS OF SCRAP TIRES HELPS TO RECOVER AND REUSE MOST OF THE VALUABLE CHEMICAL AVAILABLE IN TIRES. PYROLYSIS OF S ...

A NOVEL PROCESS AND FORMULATION ARE PROPOSED FOR PRETREATMENT OF PLASTIC SURFACES. THE FORMULATIONS ARE INEXPENSIVE NONTOXIC AND NONPOLLUTING. WHEN PLASTIC PARTS ARE IMMERSED IN THE FORMULATIONS, THE SURFACES OF PLASTICS WILL BECOME RECEPTIVE TO WATERBORNE PAINTS. THE ADHESION OFWATERBORNE PAINTS IS EXPECTED TO BE BETTER THAN THAT OBTAINED WITH SOLVENTBORNE PAINTS. MILLIONS OF GALLONS OF SOLVENTBO ...

CURRENTLY, COAL AND RESIDUAL OIL-FIRED, STEAM-ELECTRIC STATIONS ARE THE LARGEST SOURCE OF ATMOSPHERIC SULFUR DIOXIDE POLLUTANTS. THE FRACTIONAL CONTRIBUTION OF SULFUR OXIDE EMISSIONS FROM COAL IS GREATER THAN ITS FRACTION FROM OIL USED IN POWER GENERATION SINCE THE SULFUR CONTENT OF MOST OF THE COAL IS HIGHER. AMONG THE VARIOUS ALTERNATIVES THAT MAY BE USED TO REDUCE THE SULFUR OXIDE POLLUTION CAU ...
