    Hotel Terme della Sardegna (Sardinia, Italy) saves 12.000 € yearly by having a clean water system Danish Clean Water is the manufacturer of an ECA generator, which produces the disinfectant liquid, NEUTHOX. NEUTHOX is produced through an electrolysis process, where only electrical power, common salt and water is used, and is a clear 100 % biodegradable liquid which ...

  • 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 ...

  • 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 ...

  • 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, ...

  • 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 ...

  • Carbon dioxide gas case study

    Application Moisture] is measured in carbon dioxide gas pipelines and processing plants. Problem The presence of moisture in carbon dioxide gas promotes corrosion. Perhaps more significant is the fact that moisture will readily form ice when pressure is reduced. The ice can readily freeze up pressure regulators, valves, and orifice plates causing a loss of flow and even ice ...

  • 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 ...

  • Global sensitivity analysis of an in-sewer process model for the study of sulfide-induced corrosion of concrete

    The presence of high concentrations of hydrogen sulfide in the sewer system can result in corrosion of the concrete sewer pipes. The formation and fate of hydrogen sulfide in the sewer system is governed by a complex system of biological, chemical and physical processes. Therefore, mechanistic models have been developed to describe the underlying processes. In this work, global sensitivity ...

  • Hydrogen sulfide gas emission under turbulent conditions – an experimental approach for free-fall drops

    Odor nuisance and sulfide corrosion in sewers carrying septic wastewater are accelerated at points of turbulence such as drops in manholes, but accurate methods or empirical expressions to evaluate the gas stripping rate at those particular sites are still missing. With the aim of improving the current knowledge on the influence of free-fall drops on the release of hydrogen sulfide gas, an ...

  • Combating Corrosion within Power Generation Facilities

    Just about every utility facility that generates power or engages in some form of incineration must deal with corrosion issues. Since the ac Air Act of 1990, gas-scrubbing technologics have increased the im serving the assets of power plants and othe incineration infrastructure. These demands will increase further with the advent of new mercury removal requirements to be phased in during e near ...

  • ELECTRONIC WATER TREATMENT REDUCES FOULING AND CORROSION IN PIPELINES

    Increasing pressure loss in the pipeline is often caused by scale corrosion or product fouling of the internal surfaces. This condition slows transmission and distribution capacity, and can require more than just routine maintenance if it remains unaddressed. Interior corrosion, fouling and leakage in pipeline systems will adversely impact bottom-line operations. ...
