  • Real Time TOC Analysis in Steam and Condensate

    Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- ...

  • Analysis of Natural Gas Products by GC / TCD / FID

    The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific Model 910 ...

  • Determination of Total Petroleum Hydrocarbons in Soil, Sediment, and Waste Samples using the SpeedExtractor E-916

    Total petroleum hydrocarbons (TPH) are a family of several hundred chemical compounds made from crude oil. TPH are found in soils and water. Exposure to TPH can affect human health and, therefore many laboratories around the world are analyzing TPH levels in the environment. This application note describes the extraction of TPH from soil, sediment, and waste samples using the SpeedExtractor ...

  • Case study - EPH in soil with No. 6 fuel oil

    No. 6 fuel oils (heavy fuel oil, bunker C oil) is often used in industry for heat, steam or power generation. A consultant used Sitelab to investigate two different spill sites contaminated with subsurface plumes of NAPL resulting from leaking underground storage tanks (USTs). Soils were collected from borings using a drill rig and field screened for their EPH aromatic content. Split samples ...

  • Development of headspace–gas chromatography–flame ionization detection procedure to determine volatile fatty acids in zoo organic waste leachates

    In order to determine volatile fatty acids (short chain monocarboxylic acids with 2 to 6 carbon atoms in a molecule) in leachates formed in organic waste piles a procedure based on static headspace (HS) coupled with gas chromatography (GC) have been proposed and optimized. The conditions of HS extraction and sample introduction into a gas chromatograph as well as of chromatographic separation ...

  • Agronomic management system and precipitation effects on soybean oil and fatty acid profiles

    This study investigated long-term agronomic management systems and precipitation level effects on soybean [Glycine max (L.) Merr.] total oil content and fatty acid composition. Management systems evaluated included conventional (CT), no-till (NT), low chemical input (LI), and zero chemical input (ORG). Total oil content and major fatty acids profiles were analyzed by accelerated solvent extractor ...

  • Case study - Texas crude oil in soil sites

    Sunset Well Service, Inc. is an environmental contractor located in the Midland/Odessa area of Texas. They use their UVF-3100D analyzer to help excavate and remediate soils contaminated by produced water and crude oil. Laboratories in Texas test TPH using the TX 1005 GC-FID Method. This method is similar to U.S. EPA Method 8015M, but reports the GRO, DRO and ORO fractions separately. Soils from ...
