FOSSIL ENERGY RESEARCH CORPORATION PROPOSES THE DEVELOPMENT OF A NOVEL DUCT INJECTION PROCESS FOR SIMULTANEOUS REMOVAL OF SO2 AND NOX FROM COAL-FIRED POWER PLANT FLUE GASES. IN THIS PROCESS, A MIXTURE OF LIME AND A PROPRIETARY SORBENT ISINJECTED EITHER DRY OR IN THE FORM OF A SLURRY INTO THE FLUEGAS DUCT BETWEEN THE AIR PREHEATER AND PARTICULATE COLLECTION DEVICE. LIME REMOVES SO2 AND THE PROPRIET ...

CARBON ADSORPTION IS A WIDELY USED TECHNIQUE TO REMOVE AND CONCENTRATE VOCS FROM DILUTED AIR AND WATER STREAMS. PERIODICALLY CARBON BEDS ARE REGENERATED WITH STEAM. THE RESULTS OF THIS REGENERATION AFTER COOLING, IS A CONCENTRATED MIXTURE OF HAZARDOUS COMPOUNDS AND WATER. COMMON AND PARTICULARLY TROUBLESOME STREAM CONDENSATES ARE THOSE CONTAINING MIXTURES OF CHLORINATED SOLVENTS AND WATER-MISCIBLE ...

CFCS EMITTED AS PURGE STREAMS FORM LARGE INDUSTRIAL REFRIGERATORS ARE A CONSIDERABLE ENVIRONMENTAL PROBLEM AND AN ECONOMIC LOSS. MEMBRANE ORGANIC VAPOR RECOVERY SYSTEMS APPEAR TO BE ABLE TO TREAT THESE STREAMS. A MEMBRANE UNIT COULD RECOVER CFC FOR REUSE IN THE REFRIGERATOR, AND PRODUCEA CFC-DEPLETED AIRSTREAM FOR VENTING. IN THE PHASE I PROGRAM, EXISTING MEMBRANES WOULD BE FABRICATED INTO HIGH-PR ...

COAL COMBUSTION FLUE GAS THAT IS DESULFURIZED WITH LIME OR LIMESTONE RESULTS IN 30-35 MILLION TONS PER YEAR OF GYPSUM- LIKE WASTE. THIS PRESENTS A DISPOSAL PROBLEM WHICH COULD BEELIMINATED BY THE CONVERSION INTO MARKETABLE COMMODITIES. SCIENCE VENTURES HAS BEEN EXPERIMENTING WITH A NEW HIGHSPEEDCHEMICAL PROCESS TO SOLVE A RELATED ENVIRONMENTAL PROBLEM. THEIR FLASK PROCESS RECOVERS SULFUR VALUES FR ...

PROPOSED RESEARCH WILL ESTABLISH THE TECHNICAL FEASIBILITY OF A COMBINED COMBUSTION/VITRIFICATION PROCESS FOR THE TREATMENT AND DISPOSAL OF SPENT ALUMINUM POTLININGS. RE- SEARCH RESULTS WILL BE EVALUATED AGAINST PREDETERMINED CRITERIA TO VERIFY THE TECHNICAL FEASIBILITY OF THE PROCESS. SPENT ALUMINUM POTLININGS ARE PRIMARILLY GRAPHITIZED CAR- BON AND REFRACTORY MATERIALS, CONTAINING FLUORIDE, ALUM ...

THE FUTURE ECONOMIC APPROACHES TOWARD ELECTROCHEMICAL OZONE GENERATION DEPENDS ON THE DEVELOPMENT OF LOW COST, STABLE, ANODE MATERIALS WITH LONG OPERATING TIMES. IN A PRIOR EPA SBIR PROGRAM (NOW IN PHASE II) ELECTROCHIMICA CORP. HAS DEMONSTRATED VERY SUCCESSFUL ELECTROCHEMICAL OZONE GENERATION METHODS FROM A VARIETY OF ELECTROLYTES OBTAINING HIGHER EFFICIENCIES AND OZONE CONCENTRATION LEVELS. PLAT ...

TURBO ENERGY SYSTEMS AND TIERNEY TURBINES ARE TEAMED TOGETHER TO DEVELOP A NEW GENERATION OF GAS TURBINES. THE INITIAL ENGINE WILL OPERATE WITH LOW NOX AND CO EMISSIONS WHILE BURNING NITROGEN-CONTAINING CALIFORNIA HEAVY CRUDE OILIN COGENERATION APPLICATIONS. THE TURBINE'S DESIGN IS A RADICAL DEPARTURE FROM CONVENTIONAL GAS TURBINE CONCEPTS IN THAT THE TURBINE INCORPORATES LARGE EXTERNAL COMBUSTORS ...

IN DECEMBER 1983, TSANG AND SHAUB PRESENTED RESULTS OF A THEORETICAL STUDY ON THE USE OF SURROGATES AS SUBSTITUTES FOR PRINCIPAL ORGANIC HAZARDOUS CONTITUENTS (POHC) FOR VALIDATION OF DESTRUCTION AND REMOVAL EFFICIENCY (DRE) FOR INCINERATOR OPERATIONS. THE PAPER DISCUSSED SOME OF THE PROBLEMS INHERENT IN THE USE OF THE POHC CONCEPT AS A MEANS TO VALIDATE INCINERATOR PERFORMANCE AND SUGGESTED AN AL ...
