  • Serviceability assessment and sensitivity analysis of cast iron water pipes under time-dependent deterioration using stochastic approaches

    Determination of the depth of the corrosion pit is essential to predict the serviceability of corrosion affected pipes and to instigate maintenance and repairs for the pipeline system. In this paper, a reliability-based methodology for serviceability assessment of corrosion affected pipes is presented. The depth of corrosion pit is considered as the critical parameter that causes ...

  • Thermal oxidizers for natural gas savings - Case Study

    It’s in the news every day; the natural gas production industry is experiencing record growth. The gas reserves in the United States are thought to hold enough natural gas for hundreds of years and the gas and oil industry has improved extraction techniques that make gas production more affordable and less impactful on the landscape. Good news for the country and our environment. The ...

  • Scaling vs. Corrosion: Why It Matters for Your Boiler Feedwater System

    When using boilers for an industrial plant and process, one of the most important things to implement is the appropriate treatment of the boiler feedwater before it has a chance to scale and corrode equipment. Before beginning any process with a boiler, understanding the makeup and return water chemistry/characteristics, the manufacturer’s requirements for the boiler (what pressure it ...

  • Is STOP-FYRE Safe to Use? We Put It to The Test!

    We often get asked where STOP-FYRE is safe to use. It’s safe EVERYWHERE! To prove this, we sprayed STOP-FYRE on a variety of surfaces to show how it doesn’t do any damage. The non-corrosive gas element of STOP-FYRE makes it environmentally safe and won’t harm electronics, car engines, or people. In fact, we’re the ONLY fire extinguisher the ...

  • Case study - Natural gas production

    OVERVIEW The largest U.S.-based independent oil and gas producer and one of the largest independent processors of natural gas and natural gas liquids in North America was in search of new technologies to maintain the pollution control efficiency at their natural gas treatment facility. In typical gas plants, the well head natural gas needs to be treated to remove water, CO2, ...

  • Mastering the Chaos

    Random packing consists of single pieces that are poured into separation columns and form a chaotic structure. Now, Sulzer has developed a new generation of high-performance random packing that offers more uniformity of surface distribution within the packing volume. The example of a CO2 absorber shows the benefits. Columns with random packing are well established ...

  • Less Reactive, More Proactive

    OPERATORS EMBRACE INLINE TECHNOLOGIES TO ASSESS THEIR METALLIC FORCE MAINS Historically, it has proven difficult to assess the condition of pressurized mains that carry sewage, especially those made with ferrous material. Metallic force mains have special operational challenges that ...

  • Gas Detection in Public Swimming Pool Facilities

    Recreational facilities’ indoor swimming pools provide a venue for exercise, competition and fun for all ages as patrons splash, swim, dive and float around in the crystal clear water. To keep the water fit to swim in requires a disinfectant maintenance program commonly using Chlorine, or Chlorine and Ozone. Chlorine is a powerful, corrosive disinfectant and in both gas and liquid forms it ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...

  • Application of data mining techniques in building predictive models for oil and gas problems: a case study on casing corrosion prediction

    This paper describes the use of (supervised) data mining to predict casing corrosion in carbon geological storage projects. This study discusses: 1) data pre–processing such as missing value handling and discretisation; 2) feature selection methods such as correlation coefficient, signal–to–noise ratio, information gain, Gini index, and the k–nearest neighbour (KNN) approach; 3) classification ...

  • Wastewater force main management – internal corrosion survey using inline methods

    In our first post about Wastewater Force Main Management, we looked at how preliminary analysis helps operators develop a plan for managing their system. After completing this process, operators can begin putting the plan into action with preliminary surveys on specific force mains. For those at WEFTEC, you can visit Pure ...

  • When Capability is Critical

    The measurement and control of contaminants in natural gas pipeline systems are crucial to maintaining safe, reliable transport and consistent quality final product. Contaminants that require continuous analysis include total sulfurs (primarily hydrogen sulfide, or hLS), water vapour, carbon dioxide (C02) and heavier hydrocarbons (as hydrocarbon dew point temperature). The water ...

  • Combating Corrosion - Committee G01 Standards Fight Nature’s Destructive Tendencies

    The evening news may leave many of us feeling war-weary, but one ASTM International technical committee has been successful in conflict of a different sort. It’s a commonplace but epic struggle between the natural and civilized worlds — the fight against metal corrosion. For the past half-century, the weapon of choice of ASTM Committee ...

  • Quadrasperse Quadpolymer solves major fouling problem at large Gulf Coast Petrochemical Plant

    Background As a result of poor results with a previous water treatment supplier, ChemTreat was given the opportunity to turn things around in a large, open recirculating cooling system for a Gulf Coast chemical plant. The cooling system serviced a light olefins unit with multiplestage, cracked-gas compressor after-coolers operating at a high skin temperature. At a maximum skin temperature of ...
