  • Analytical Testing for Corexit Dispersants Used in the Gulf Spill

    The analysis of various sample matrices (seawater, sediment, tissue) to determine concentrations of Corexit dispersants used in the Gulf spill requires the use of one or more of the components in the dispersant as a tracer. The primary active ingredient (i.e. the primary surfactant) in the Corexit products is Dioctyl Sulfosuccinate Sodium Salt (DOSS). The other primary ingredients function as ...


  • Oil and gas industry process analytics in ethylene production plants – Case Study

    Ethylene is the largest volume industrially produced organic material and its majority is used in the production of polymers and derivatives. Between a variety of processes the thermal cracking of hydrocarbons in the presence of steam (steam cracker) is mostly used. Regardless of the process type, all plants require process analytical equipment to collect reliable and accurate process data for ...

  • Use of process analytics in aromatics (BTX and Phenol) production plants – Case Study

    Aromatics are planar, cyclic compounds with conjugated double bonds, consisting of the elements carbon and hydrogen. Aromatics are important intermediates and used as starting materials for a wide range of products. Aromatics are derived from crude oil and, in small quantities, from coal. Process automation equipment including gas chromatographs and other process analyzers contribute essentially ...

  • Use of process analytics for cracking processes in refineries – Case Study

    Crude oil processing Crude oil is a complex mixture of hydrocarbon compounds and relatively small quantities of other materials such as oxygen, nitrogen, sulphur, salt and water as well as inorganics and metals. It occurs naturally in the ground and was formed millions of years ago. Crude oil varies from source to source in composition and colour. It is typically mixed with gases, which have to ...
