Problem Statement Various processes and tools in the modern wafer fab plant produce effluent streams that contain unacceptably high levels of perfluorocarbon GWGs (greenhouse warming gases). These effluent streams are abated by plasma incineration and wet scrubbers and other techniques. It is necessary to measure the destruction removal efficiency (DRE) of the various abatement methods ...

Problem Statement Replacement of PFA seals inside the reactor chamber is performed according scheduled maintenance and life expectancy of the seals. Early degradation of seals goes completely undetected until there is a complete failure of the seal, letting atmospheric contaminants inside the reactor and forcing an unscheduled reactor downtime. IRGAS ...

Public confidence in CCS projects worldwide is not very high. Many believe that CCS is not permanent storage, and at great expense to govermnents who are funding these projects. Effective monitoring and verification programs could go a long way to improve public perception.  Our Spectra-1 open path TDLAS gas sensor has shown very high accuracy in monitoring ambient CO2 levels. Better than ...

The unidirectional and conventional flushing methods are compared in this study and the water amount and flow velocity at junctions within an EPANET water distribution network are compared. In the unidirectional method, the necessary flow and water pressure for the minimum flow velocity for flushing become greater when pipe diameter exceeds a certain value. Therefore, the maximum length of ...

Hydrogen usage is growing. The general public sees and reads about hydrogen as an alternative fuel for cars. However, the big use for hydrogen is found in hydrocarbon processing and other important manufacturing processes. Hydrogen is the first element on the periodic table and is an essential element in the manufacturing of many of our everyday products. We must have respect for its explosive ...

Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...

Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...

Abstract—The southern area of Italy is characterized by the presence of many active volcanic areas. In Pozzuoli (Naples, Italy), an urban area characterized by high volcanic risk, a gas emitting site is present. An high percentage of CO2 is emitted, whose atmospheric concentration measurement is an important task in many environmental and scientific applications. In this paper, we describe the ...

Abstract In this paper, we present results from field studies of the application of a new laser based spectrometer incorporated with real-time dispersion modeling techniques to measure fugitive emissions from gas processing facilities. While open-path FTIR spectrometers can measure a variety of gaseous species, they suffer from the drawbacks of being large, expensive and of limited range. Also, ...
