THIS PROPOSAL PRESENTS A CONCEPT FOR A CHEMICAL MONITOR BASED ON DIFFERENTIAL CATALYTIC REACTIVITIES AND LARGE REACTION EXOTHERMICITIES. THE SIMPLICITY OF THE PROPOSED SENSOR CONCEPT PROMISES AN ECONOMIC AND RELIABLE MONITOR FOR IN-SITU MEASUREMENT OF A VARIETY OF GASES. IN THIS PROJECT, ENVIROCHEM, INC., WILL INVESTIGATE THE APPLICATION OF THIS CONCEPT FOR MEASURING AMMONIA IN FLUE GASES. A SENSI ...

AS A RESULT OF RECENT PROBLEMS SUCH AS THE OIL LOSS PHENOMENON IN SOME MODELS OF ROSEMOUNT PRESSURE TRANSMITTERS, THE NUCLEAR INDUSTRY HAS BECOME INTERESTED IN FIBER OPTIC PRESSURE TRANSMITTERS. THESE TRANSMITTERS ARE POTENTIAL CANDIDATES TO REPLACE THE EXISTING PRESSURE TRANSMITTERS IN THE SAFETY AND NON-SAFETY SYSTEMS OF NUCLEAR POWER PLANTS. FURTHERMORE, FIBER OPTIC PRESSURE TRANSMITTERS MAY BE ...

N/A

Billions of gallons of oily wastewaters are generated daily by a variety of industrial sources. A large fraction of these are oil/water emulsions for which current treatment technologies are often costly and ineffective. Although such emulsions can be separated using crossflow filtration technology, conventional crossflow membranes typically are uneconomic for performing such treatment due to st ...

Incineration of Municipal Solid Wastes (MSW) often results in the emission oftoxic heavy metals, such as lead and cadmium. Previous work has demonstrated theability of some aluminosilicates sorbents, including common coal-borne minerals,to capture lead and cadmium vapors and, thereby, prevent their emission. Leadand cadmium capture by such sorbents have been shown to be non-leachable. PSITechno ...
