  • `Testing VOC Evaporation Losses from Floating Roof Tank Turnover,` published in Oil and Gas Journal, December 10, 2001

    Abstract Air emissions from floating roof tanks have been well characterized and documented by the U.S. Environmental Protection Agency (EPA). The estimation methods have been revised and updated throughout the years. However, an unusual aspect of air emissions from tanks with a floating roof during a tank turnover has not been addressed.  Petroleum storage tank floating roofs are ...

  • Determination of appropriate operational parameters of a floating–drum biogas plant for rural Nigeria

    This paper determined the appropriate operational parameters of a floating–drum biogas plant that give the highest gas production rate (m³/h), best gas quality (% methane fraction) and required output pressure (mbar) for burners. The operational parameters were retention time and weight on the floating drum of the plant. The retention times of 15, 20, 25, and 30 days, and weights of 50, 100, 150 ...

The need for an upgraded ...

  • Optimizing water management in hydraulic fracturing for shale oil and gas production

    Centralized treatment of wastewater is emerging as a viable solution for long-term efficiency in managing water sourcing and wastewater treatment in hydraulic fracturing. The number of hydraulic fracturing (fracking) shale oil and gas wells in the United States continues to increase. Within the Bakken Shale formation alone, in North Dakota and Montana, upwards of 15,000 hydraulic fracturing ...

  • Carbon Monoxide, Carbon Dioxide and Indoor Air Quality

    Chances are that unless you are hot or cold – or if you smell something funny – you probably never think about indoor air quality. However, scientists know that gases in the air that you cannot see or smell can still affect your health. Carbon Monoxide The most dangerous gas most of us will ever face is carbon monoxide (CO). Not normally occurring in nature, this ...

  • Glasgow City Council, UK

    Two years ago the Glasgow City Council announced a major clean-up of the Clyde as part a regeneration programme. The clean-up was regarded as an important element in attracting tourists to the cities riverside and its continued development. However two rivers, the Cart and Kelvin flow into the River Clyde and bring with them hundreds of tonnes of floating litter and debris right onto the ...


  • Evaporator Limits Boron to 5 PPM at award-winning chemical plant

    Problem: The biggest challenge confronting Rohm & Haas Corp. in building a wastewater plant for its chemical facility in Elma, Wash., was meeting Washington State Dept. of Ecology limitations on boron of 5 ppm. The Elma plant manufactures sodium borohydride, a versatile chemical used in a variety of applications ranging from the generation of sodium hydrosulfite for reductive bleaching of ...

  • Balancing growth and conservation - Precast concrete manholes become part of the stormwater solution

    When American Fork, Utah, decided to approve construction of a 175-acre commercial center, the city engineers had to consider the environmental effect it would have on a 45-acre wetland right next door. Under the EPA´s Phase II Storm Water Rules, adapted in late 1999, almost any city large enough to require a storm sewer system must balance growth with the environmental impacts of ...

  • Multifunctional Well Implemented for In Situ Remediation of Hydrocarbon Contaminations in Soil and Groundwater

    Abstract A recently developed Multifunctional Well has been implemented for the remediation of subsurface contamination caused by hydrocarbon spills. Four different remediation processes can be operated within the same well. At optimal efficiency of each remediation process, successive treatment of the capillary fringes, the vadose zone, and the aquifer can be accomplished. Each treatment ...


  • Cardiff Harbour Authority, UK

    The regeneration of Cardiff Bay created a complementary development of housing, leisure, business and commerce - however they had a problem. Debris, rubbish and invasive aquatic weed was entering the bay from two rivers (approx 500 hectres water space). Cardiff Harbour Authority launched a competitive tender for a range of equipment to undertake a wide range of environmental responsibilities. ...


  • Pumps for the Booming FPSO Sector

    In the last few years, several new offshore oil fields have been discovered. The current findings from Petrobras and other companies in the pre-salt province, located in the Brazilian continental shelf, suggest reserves of over 50 billion barrels of oil. Extracting the pre-salt oil is challenging and done increasingly with floating production storage and offloading units (FPSOs). Sulzer offers a ...

  • Presumptive Remedies

    A presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site. EPA is establishing presumptive remedies to accelerate site-specific analysis of remedies by focusing the feasibility study efforts. EPA expects that a presumptive remedy, when available, will be used for all CERCLA sites except under ...
