  • The risky business of resource recovery

    Waste management operations, like any transport business, have many risks attached to them and all operators should avoid the “Dodgy Brothers” ignore-the-risks to save costs approach! Any transport business with large vehicles working in tight city and site access areas is prone to accidents and near miss incidents. Add to that the hazards of working with lifting, loading and compacting systems. ...

  • Free-Product Recovery Methods and Issues

    During my 33 years in the environmental field, I have been involved in a lot of sites with free product.  In the 1980’s light non-aqueous phase liquids (LNAPL) such as gasoline were removed by the following methods: Bailing with a hand bailer from a well Pumping with a 2 pump system (depression pump and product pump) Pumping with a total fluids pump and separating ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • UV disinfection for enhanced oil recovery and other oilfield applications

    One of the biggest challenges facing oil companies today is how to extract more oil from the discoveries made in the last 40 years. Estimates vary, but approximately 66% of the discovered oil gets left in the ground. The International Energy Agency has estimated that if, in the next 20 years, this figure could be reduced to 50%, then this would increase the world's recoverable oil by 1.2 trillion ...

  • Eccentric Disc Pumps Create Product Recovery Cost Savings

    As budgets tighten, operators of manufacturing facilities must implement new ways to meet established production quotas while spending less money. Improved operational efficiencies can critically affect the profitability of food and beverage, pharmaceutical, and cosmetic manufacturers, from the most basic productionline level through entire plant efficiencies, and even overall corporate ...

  • Microalgae growth for nutrient recovery from sludge liquor and production of renewable bioenergy

    Proof-of-concept has been demonstrated for a process that will utilize nutrients from sludge liquor, natural light, and CO2 from biogas to grow microalgae at wastewater treatment plants. This process will reduce the impact of returning side-streams to the head of the plant. The produced algae will be fed to anaerobic digesters for increased biogas production. Dewatering of anaerobically digested ...

  • Recovery of aluminium alloys and some valuable salts from Spent Bottle Covers

    This work provides a method to prepare standard Al-alloy(s) and some salts of market value from Spent Bottle Covers (SBCs). Aluminium covers were separated from others made of iron or plastic by magnetic and flotation techniques. The aluminium covers were melted under flux. Metals went into the slag were leached using hydrochloric acid. Results obtained revealed that the removed paint decomposed ...

  • Analytical Solutions for Free-Hydrocarbon Recovery using Skimmer and Dual-Pump Wells

    Accidental release of petroleum hydrocarbons to the subsurface may occur through spills around refineries, leaking pipelines, storage tanks or other sources. If the spill is large, the hydrocarbon liquids may eventually reach a water table and spread laterally in a pancake-like lens. Hydrocarbons that exist as a separate phase are termed light non-aqueous phase liquids (LNAPL). The portion of the ...

  • Integrated solar and wind energy powers oil recovery system

    Recovery of free-product petroleum at the former St. Croix Alumina (SCA) site in Kingshill on St. Croix, VI, is addressing ground-water contamination caused by past releases of fuel and refined petroleum at SCA. The oil recovery system employs wind-driven turbine compressors (WTCs), wind-driven electric generators (WEGs), and photovoltaic (PV) panels to power pneumatic and electric submersible ...

  • Viscosity correlations for light Omani crude using artificial neural networks

    Predicting the crude oil viscosity is very crucial to the oil industry. Accurate prediction of the viscosity will lead to a better design of an energy efficient transportation system and helps in determining the enhanced oil recovery method. There has been intensive work in generating viscosity empirical correlations for under–saturated, saturated and deal oil. Due to the rapid growth in ...
