APPROXIMATEL HALF OF AUTOMOTIVE NOX IS RELEASED IN THE INITIAL MINUTES AFTER STARTUP, WHEN THE CATALYTIC CONVERTER IS COLD, AND IS A SIGNIFICANT SOURCE OF ACID RAIN. THIS PROJECT WILL DETERMINE THE FEASIBILITY OF REVERSIBLY ADSORBING THIS "COLD-START" NOX IN A SORBENT BED AND SUBSEQUENTLY RELEASING THE NOX INTO A THREE-WAY CATALYTIC CONVERTER TO BE REDUCED. THIS COULD REDUCE THE ENVIRONMENTAL NOX ...

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 ...

LOW COST, REMOTE SENSING OF PARTICLE-LADEN PROCESS STREAMS REQUIRES CONTINUING INSTRUMENTATION DEVELOPMENT TO MEET THE THE NEEDS OF FOSSIL ENERGY AND OTHER INDUSTRIAL APPLICATIONSPARTICULATE EMISSIONS CONTROL WHICH IS CONSISTENT WITH PROCESS OPTIMIZATION IS HIGHLY DEPENDENT ON THE ENTERING PARTICLE SIZE DISTRIBUTION AND CONCENTRATION. ON-LINE ANAL-YSIS AND FEEDBACK CONTROL DEVELOPMENT WILL PERMIT ...

THE THREE-WAY CATALYTIC CONVERTER IS THE MOST IMPORTANT DEVICE MAKING TODAY'S AUTOMOBILES COMPLY WITH EXISTING EMISSION LAWS. THE FIRST TWO OR THREE MILES IN A TYPICAL 22-MINUTE, 12-MILE COMUTE IN TODAY'S VEHICLES RESULT IN THE EMISSION OF HALF OF THE TOTAL NON-METHANE HYDROCARBONS, WHICH RESULT IN THE PRODUCTION OF URBAN SMOG, AS WELL AS HALF OF THE TOXIC CO EMISSIONS. THIS OCCURS BECAUSE THE CAT ...

ORGNAIC VAPOR-LADEN INDUSTRIAL AIRSTREAMS ARE A GROWING POL-LUTION PROBLEM AND A WASTE OF RESOURCES. THE METHODS NOW AVAILABLE FOR TREATING THESE AIRSTREAMS ARE INADEQUATE, ESPECIALLY WHERE CHLOROFLUOROCARBON SOLVENTS ARE INVOLVED. THE USE OF MEMBRANES TO RECOVER ORGANIC VAPORS FROM CONTAMI-NATED AIR HAS BEEN STUDIED AT MEMBRANE TECHNOLOGY AND RE- INC. SINCE 1982, AND THEY HAVE COMPLETED LABORATOR ...

THE CLEAN AIR ACT AMENDMENTS OF 1990 INCLUDED STANDARDS FOR VOLATILE ORGANIC COMPOUND (VOC) EMISSIONS FROM EQUIPMENT LEAKS (FUGITIVE EMISSIONS) AND FROM SMALL VENT STREAMS. SUCH EMISSIONS ARE ESTIMATED TO TOTAL 330 MILLION KG/YEAR; ADDITIONAL CONTROLS REQUIRED BY THE NEW ACT ARE EXPECTED TO COST INDUSTRY ALMOST $120 MILLION/YEAR FOR THE NEXT DECADE AND BEYOND. VERY SMALL (1-3 SCFM) MEMBRANE VAPOR ...

CHLORINE RANKS AMONG THE TEN MOST IMPORTANT COMMODITY CHEMICALS. APPROXIMATELY 54% OF THE TOTAL U.S. CHLORINE PRODUCTION IS LIQUEFIED FOR SALE OR FOR IN-PLANT TRANSPORT. TAIL GAS PRODUCED FROM THE CHLORINE LIQUEFACTION PROCESS IS THE PRINCIPAL SOURCE OF CHLORINE-CONTAINING WASTE GAS STREAMS PRODUCED BY CHLOR-ALKALI PLANTS. CURRENTLY, SUCH STREAMS ARE TREATED BY ABSORPTION IN CARBON TETRACHLORIDE; ...

OVER THE LAST SEVERAL YEARS, THE EPA HAS DEVOTED MAJOR EF- FORTS TO IDENTIFY AND DOCUMENT THE MAGNITUDE OF THE RISKS OFENVIRONMENTAL POLLUTION DUE TO LEAKING UDERGROUND STORAGE TANKS (UST). IN APRIL 1987, THE EPA PUBLISHED THE PROPOSED REGULATIONS FOR THE OWNERS AND OPERATORS OF UST, WHICH ARE EXPECTED TO BE FINALIZEDD IN EARLY 1988. THESE REGULATIONS INCLUDE REQUIREMENTS FOR TANK TIGHTNESS TESTS, ...

STRINGENTLY REGULATED OZONE NONATTAINMENT AIR QUALITY REGIONS WILL REQUIRE THE IMPLEMENTATION OF ULTRA-LOW-NOX SYSTEMS. CURRENTLY, ONLY COSTLY SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEMS CAN ACHIEVE VERY HIGH LEVELS OF NOX REDUCTION. INEXPENSIVE LOW NOX BURNERS, THAT CAN MEET THE REGULATIONS WITHOUT SCR, ARE URGENTLY NEEDED BY INDUSTRY. RECENTLY, PROGRESS HAS BEEN MADE TOWARDS DEVELOPING A SUB-9 P ...
