  • Low natural terrestrial radioactivity in oil–derived lubricants

    Oil and gas production processing operations have been known to involve naturally occurring radioactive materials that lead to internal and external radiation hazards and thus a significant radiation dose to the workers. In this work, samples of nine oil lubricants used on a daily basis were collected from local suppliers in Egypt and analysed to determine their natural radioactivity. The ...

  • How to treat radioactive NORM sludge with VacuDry

    NORM doesn’t sound like a big thing. But Naturally Occurring Radioactive Material might let the alarm bells ring. Everyone has heard of “radioactive material” and that sounds dangerous. However, most of this material is trapped deep in the ground beneath our feet. From there it reaches the surface, for example via the water cycle. Another possible pathway for NORM to reach the ...

  • Mercury recovery from industrial waste and toxic residues of natural gas drilling

    econ's client in the east of Germany is one of the few specialised companies in Europe for the treatment of mercury contaminated waste. Typical input material for this type of treatment is sludge from the natural gas industry or other residues from chemical processes, i.e. contaminated filter cake from waste water treat-ment. Among their most important clients are Shell, ExxonMobil, Wintershall ...

  • NORMs contamination treatment using Ivey-sol technology

    NORMs (naturally occurring radioactive materials) are found almost everywhere, and many natural materials, such as the earth’s crust, contain such radioactive materials. So what happens when oil and gas activities such as petroleum refining and natural gas extraction, disturb such radioactive material? They can alter the natural background radiation — the radiation that we are naturally exposed ...

  • Is Radon & Radiation from Granite Countertops a Concern?

    Over the past several years there have been numerous media reports about possible health concerns regarding granite countertops emitting radiation and radon gas into people’s homes and businesses.  Granite’s durability and decorative appearance have made it a popular building material in many homes and buildings. Almost any type of rock could contain naturally occurring ...

  • econ VacuDry® technology proves successful for the treatment of NORM wastes

    Large amounts of drilling sludge containing low levels of natural radioactivity is a resultant by-product of the oil and gas production process. These so-called NORM-sludges (Naturally Occurring Radioactive Material) are often contaminated with both mercury and hydrocarbons. The econ industries VacuDry® technology is recognized in Germany as the first choice for the extraction of the mercury ...

  • Opinion: Legislating for tomorrow`s problems today - dealing with intergenerational equity

    The question of how we protect the ‘future’ is central to the concept of sustainable development; it is the forward thinking that makes the idea of sustainable development so challenging. The increasingly dire warnings of the consequences of our present behaviour on global climate change bring the issue into sharp focus. From my personal perspective, it seems that we have reached the stage of ...


  • FRACKING: Freeing Energy Resources versus Polluting the Earth and Public Health with Radiation and Toxic Chemicals?

    Fracking demands the use of millions of gallons of water, precious drinking water, and sand infused with up to 1,000 different toxic chemicals to fracture the shale rock and release the trapped gas or oil. The wastewater, brine, and sludge are then returned to the surface and in need of disposal. Unfortunately there is not yet a clear and safe method of disposal or storage. Among these chemicals ...

  • Ionising Radiation

    Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

  • Questions And Answers About Saltwater Spills

    An estimated 1 million gallons of saltwater generated by oil drilling has leaked from a North Dakota pipeline, company and tribal officials say, and federal authorities are investigating whether any of the liquid reached Lake Sakakawea, one of the nation's largest man-made lakes. Here are some questions and answers about the spill and saltwater: Q: How does oil drilling produce ...

  • Radiometric ratings for phosphogypsum in industrial areas in Romania

    In order to assess the potential environmental risk of phosphogypsum and to establish a future and proper pollution management plan of gyp–stacks and waste dumps resulted due to the operation of former chemical plant, several types of measurements have been made. This paper presents the atmospheric radon concentrations measurements for phosphogypsum deposits in three areas of chemical industry. ...

  • Green machine takes new tangent on wastewater reuse

    The idea came to Jason Snydmiller while he was on the island of Borneo. At the time, Snydmiller had learned that the super-major – one of the six largest non-state-owned energy companies – he was under contract to would promptly fine any contractor that left oil in local waters. Although it seemed callous then, the rule was essential, since locals depended on the water for fishing and prawn ...


  • Extensive remediation of superfund site - case study

    The 80 acre site, formerly a minerals processing facility, was operated primarily to recover lithium and other rare-earth minerals from ores. Raw ores were imported to the site for processing. During one phase of its operations, the facility also processed uranium ores for the government. The site was listed as by the U.S. Environmental Protection Agency (EPA) as a Comprehensive Environmental ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • On-site water treatment service cuts costs

    After more than two decades in the global oilpatch, Stuart Snydmiller thinks the future for his startup firm is in water, not petroleum. Or at least waste water.Tangent Environmental Technologies, owned with brother Jason and others, has taken existing technologies and put them together into a package that offers huge savings for drilling firms and any industrial operation that needs to process, ...


  • Toxicological and Environmental Safety Data - Case Study

    Introduction AGRAGEL is a cross-linked copolymer of acrylic acid and acrylamide partially neutralized as potassium/ ammonium salt. The polymer is in its dry form a granulate and forms a gel-like material upon addition of water or aqueous solutions. Due to the cross-linking it is insoluble in water. Uptake of water is facilitated mainly by the negative carboxylic groups of the polymer and ...

  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • Utilizing unconventional water sources for industrial reuse

    Reclamation and reuse of unconventional wastewater sources for plant raw water, cooling water and process pre-treatment has increased substantially due to increases in the cost of drinking water, recurring water shortages that can impact business operations, and tightening government regulation. Water is required in almost every industrial sector for the processing and manufacture of products. ...
