  • 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- ...

  • TOC Analysis for Standard Methods 5310B: High-Temperature Combustion Method

    Introduction Total Organic Carbon (TOC) is a rapid method that analyzes for organic carbon and expresses the result as the amount of carbon found. It is a non-specific method unable to distinguish between various organic species and only indicates that organic carbon compounds are present. Organic carbon analyzers operate by the determination of the amount of total carbon present in a ...

  • Digital Technology to Transform Oil, Gas Hiring Practices

    The oil and gas industry’s effort to adopt digital technology not only will impact its daily operations, but its hiring needs as well. The oil and gas industry must pursue digital technology for two reasons: an aging workforce and increased focus on safety, said Mike Weast, IT regional vice president with professional staffing firm Addison Group, in a statement to Rigzone. As the majority ...

  • UncerTZ Consortium - Time to Depth Conversion Evolved

    Near the end of 2015 Geovariances committed itself into building a new, sophisticated tool for Time to Depth conversion in Reservoir Characterization. The challenges petitioned by the consortium partners were not easy. It included features such as: more choices in conversion (and less of a “black box”), uncertainty characterization, inclusion of faults in the conversion procedure, ...

  • Optimization of a microwave-assisted extraction procedure for the determination of selected alkyl, aryl, and halogenated phenols in sewage sludge and biosolids

    A microwave-assisted extraction method for the determination of 15 alkyl, aryl, and halogenated phenols in sewage sludge and biosolids samples was developed and optimized. The effects of solvent, temperature, time, moisture content, acid, and number of extractions on the recovery of phenols were evaluated. Results indicated that extraction solvent had the greatest impact on the recovery of all ...

  • Improving flow distribution in influent channels using computational fluid dynamics

    Although the flow distribution in an influent channel where the inflow is split into each treatment process in a wastewater treatment plant greatly affects the efficiency of the process, and a weir is the typical structure for the flow distribution, to the authors' knowledge, there is a paucity of research on the flow distribution in an open channel with a weir. In this study, the influent ...

  • Gas Dilution With The Equal Capillaries Technique

    The advantages of the equal capillaries technique are surprising and leads to reach accuracy values of one order of magnitude higher than all the other dynamic dilution techniques. This comparison will be supported by analyzing the accuracy available with two different techniques. Nozzles (sonic or non-sonic) technique With this technique, a series of different size nozzles is used ...
