  • MAXUM II - Perfect on-line gasoline analysis using the MAXUM II process gas chromatograph – Case Study

    Gasoline is a petroleum-derived liquid and primarily used as fuel in combustion engines. The analysis of gasoline for its chemical composition is extremely important as e. g. the concentration of individual hydrocarbons determines the octane number as well as the emission characteristics of gasoline. Therefore, great efforts are made to serve producers of gasoline with an efficient tool for ...

  • On-Site Analysis of Gasoline Range Organics (GRO) in Soil and Groundwater Using Field Portable Purge and Trap GC / FID / PID

    Although leaking underground storage tanks account for the majority of gasoline contamination in soils and groundwater, other events such as accidents during product transportation or delivery are also significant. Spill clean-ups and tank replacements have an immediacy to them due to the very steep relationship between delay and cost. Since gasoline is highly mobile in the environment, it is ...

  • By the numbers: Analyzing the U.S. National Climate Assessment

    The draft U.S. National Climate Assessment was released last week, confirming that the climate is changing, that it is primarily due to human activities, and that the United States is already being adversely impacted. These top-line messages ...

  • MAXUM edition II - Total sulfur analyzer – Case Study

    To comply with environmental regulations in the production of low-level sulfur fuel, it is necessary to get reliable information about the product quality and sulfur content. The Siemens Maxum II, Total Sulfur on-line process gas chromatograph, provides this information in reliable manner using process suitable analytical procedures. The Total Sulfur solution applies a continuous sample ...

  • NH3 Slip Monitoring in Fluidized-bed Catalytic Cracking Using the LDS 6 Gas Analyzer – Case Study

    Fluidized catalytic cracking (FCC) units are used in refineries to convert low value heavy oils into more valuable lighter compounds. Cracking units are sources of emissions of pollutants (e.g. NOx) and must comply with concentration permits set by local or federal authorithies. Modern technologies are applied to reduce the content of pollutants and to monitor certain gas compounds (here: NH3) in ...

  • Portable IR analyzers: the ideal measurement solution for biofuels blend quality and wastewater testing

    Two challenges facing the biofuels industry involve compliance with blend quality standards and wastewater regulations. According to a study done by the National Renewable Energy Laboratory, 1 the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry about whether the blend ratio is correct until a problem occurs. For ...

  • Locate buried monitoring wells case study

    A Phase II Environmental Site Investigation was being conducted at a gasoline station in Fort Myers, Florida. In order to minimize costs, our client intended to use several existing on-site monitoring wells rather than installing new wells. However, five of the existing wells had been covered with asphalt and were no longer visible. GeoView was tasked with performing a shallow geophysical study ...

  • Advances in flashpoint testing: economic impact

    Flashpoint testing is one of the oldest methods of the ASTM D02 Committee on Petroleum Products and Lubricants, which was formed in 1904. The most prevalent standards are ASTM D56 (Tag Method), D92 (Cleveland Method), and D93 (Pensky-Martens Method). These classical techniques, commonly referred to as open-cup and closedcup methods, share a common principle: A test flame is lowered into the ...
