  • Solvent-free oil-in-water analysis

    Non-ionic surfactants can homogenize oily, produced water samples, creating optically clear microemulsions that are ideal for fluorescence measurements [1]. The use of surfactants to reduce fouling and improve the performance of on-line, fluorescence-based, oil-in-water monitors has been reported previously [2,3]. This paper describes the use of surfactants to prepare discrete water samples ...

  • Chlorinated solvents: methylene chloride and TCE

    Introduction This paper presents the results of a scaled and phased approach to source remediation of high concentrations of recalcitrant chlorinated solvent compounds via soil vapor extraction (SVE) and vapor treatment at a Site in Southern California. Phase I began with refrigerated condensation (C3) in order to achieve high mass removal rates to reduce lifecycle costs and time ...

  • A Simplified Procedure for the Determination of TPH’s in Waters and Soils Using the HC-404 System

    The determination of Total Petroleum Hydrocarbons (TPH), greases, and lubricant residues are important environmental and industrial tests. Fuel and lube oils can be determined in water and soils to track spills and storage tank leaks, while many military and industrial situations require certain components (gas regulators, space shuttle components, weaponry parts, etc.) to have a maximum limit of ...

  • Matching Oil in Water Analyses with Regulatory Methods - Case study

    When analyzing oil and grease in water while out in the field, it is important to use an EPA approved method and equipment. While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, ...

  • Oil in Water Analysis Method Match Regulatory Method - Case study

    The analysis of oil in water is a worldwide problem that crosses many industries, analytical methods and regulatory agencies. For those in the petroleum industry, the offshore platform oil and grease limits for produced water can be quite different from the effluent coming out of the refinery. For the expanding hydraulic fracturing industry, oil in water limits are driven by whether the frac or ...

  • Will your oil in water analysis method match the regulatory method?

    Anyone involved in field analysis of oil in water will continually get the question “Does your equipment match the regulatory method?” While the amount of oil in water is highly regulated -- it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the ...

  • Information On Chemical Composition Of Silica Gel

    Silica gel alias: Silicic acid gel. It is a highly active adsorbent material and an amorphous material. The main component of silica gel is silica, which is chemically stable and does not burn. It has an open porous structure with strong adsorption and can absorb a variety of materials. When dilute sulfuric acid (or hydrochloric acid) is added to the aqueous solution of water glass, it will ...

  • Contaminated soils and sludge treatment plant - Case Study

    Client: Ecosistem Group, Lamezia Terme (CZ) – Italy Challenge: to transform waste into product! The Client possesses a large plant for the treatment of products contaminated with hazardous substances and materials, recycling of recovered materials and disposal of non-recyclable waste, which is considered highly ...

  • Case study - RTOs leave nothing to HAP-penstance

    PROBLEM The United States EPA promulgated a ruling in 40 CFR, imposing strict new standards to reduce emissions of toxic air pollutants from the manufacture of pharmaceutical products, including prescription and over-the-counter drugs. The agency's rule was intended to reduce emissions of a number of air toxins and hazardous air pollutants (HAPs), including methylene chloride, ...

  • The Evolution of Glycol Contactors

    The dehydration of natural gas is an integral part of many gas processing applications. Dehydration with triethylene glycol (TEG) is effective and has been successfully employed in both onshore and offshore facilities. The dehydration of natural gas is an integral part of many gas processing applications. Water can form hydrate crystals with hydrocarbons and acid gases (CO2 and H2S). ...
