  • What`s the Best Air Pollution Control Technology for My Process?

    Air pollution control equipment is not something that business owners address by saying, “Let’s do the right thing for the environment and install an oxidizer!” In fact, the scenario is more likely to be “We need to increase productivity (always a good thing!), but that will put us over our annual emissions limits. Do we know what we will need? Where do we start? Who can ...

  • Horizontal Well Systems for Improving Remedial Efficiency and Zone of Influence

    To improve remediation efficiency and expand the zone of influence, Directional Technologies, Inc. transferred technology from the oil and gas industry to the environmental industry. The oil and gas industry has used directional drilling for decades to improve oil recovery, based on a simple concept that the more screen contact there is with the “pay-zone,” the more production gained. ...

  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • F4 Spill In Situ Bioremediation Applications

    F4 Completed an in situ water bioremediation program of Bio-ReClaim in northern Alberta; a pipeline leaked crude oil over a 14 hectare area in muskeg. Alberta Environment (AEP) allowed the in situ water application of Bio-Reclaim by F4 Environmental. Keeping in mind the application was performed without any ground disturbance and extremely cost effective compared to the ...

  • Energy recovery from gas compressors

    With the development of natural gas recompression plants, linked to the opening of the global gas market, which means increased exchanges and transportation between production and consumption areas, the number of energy recovery projects on this type of installation is ...

  • Gas injection to increase recovery from the Bakken formation

    The Bakken formation, in the Williston Basin, has tremendous oil reserves estimated to be in the hundreds of billions of barrels. During the last decade, the Bakken has been rapidly developed with advances in horizontal drilling and improved multi–stage hydraulic fracturing. The primary recovery factor, however, has remained very low, around 5%–10% due in part to the extremely low permeability. ...

  • Replacing of mechanical compressors by gas ejectors in flare gas recovery systems

    One of the main concerns of humankind in this century is the global warming induced by the increasing concentration of greenhouse gases in the atmosphere. A promising process for controlling the atmospheric CO2 level is prevention of combustion in flares causing high losses of raw material and energy that could generate more desired products. In the present work, a flare gas ...

  • EPA mandates proper refrigerant gas recovery processes

    New EPA regulations require facilities that use air conditioning and refrigeration equipment to have a refrigerant recovery plan in place. The plan is needed to make sure that any harmful gases that might leak are captured. Refrigerant gases contain hydrochlorofluorocarbons, known to cause severe damage to the ozone layer and to promote global warming. A comprehensive plan is now in place to ...

  • Liberating contaminants for easy recovery

    The number one challenge associated with most site remediation designs and methodologies is that 90-95 per cent of all environmental contaminants are present in an adsorbed phase onto soil and bedrock surfaces within both saturated and unsaturated zones. Contaminants, including hydrocarbons (LNAPL), chlorinates (DNAPL) and heavy metals, are sorbed onto the substrates and so have reduced mobility ...

  • Recovery Costs Less

    Bal K. Kaul, Ajit Sapre and Lei Zhang, ExxonMobil Research and Engineering Co. and Daryl Musselman and Surajit Roy, Quest Air Technologies, describe a new low cost H2 recovery process. Hydrogen recovery from fuel gas and hydrogen containing purge gas streams in refinery and chemical processes offers many potential benefits including process uplift, reduced hydrogen costs, avoidance of H2 plant ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • Enhanced liquid recovery by carbon dioxide sequestration in gas/condensate reservoirs

    CO2 sequestration in a depleted gas/condensate reservoir could be a viable option due to the economic benefits associated with the enhanced liquid recovery. According to previous laboratory investigations, CO2 may be superior to methane (CH4) or nitrogen (N2) ...

  • Power Substation and a Gas-Fired Combustion Turbine and Heat Recovery Steam Generator

    B&V Energy expands the world's largest nitrogen plant by constructing a cogeneration plant supplying the additional power needed to reach resources deep in Mexico's offshore oil field. Metropolitan Mexico City has a population of approximately 20 million and is one of the most densely populated areas in the world, requiring an extraordinary amount of gas and oil to satisfy its growing energy ...

  • 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 ...

  • Optimization of a Sulfur Recovery Unit

    Prior to Suncor’s purchase of the Spirit River facility, little attention was given to the LO-CAT unit. In general, over injecting chemicals into a LO-CAT unit will not result in operating problems, just higher than required operating costs. Consequently, in remote gas plants such as Spirit River, it is sometimes difficult to convince operators to change operating conditions if the unit is not ...

  • VaporRemed helped in recovery of pets

    We recently converted our oil boiler to gas and the heating crew could not remove the half-full, 250-gallon oil tank until one week later. Hence, we had an open fuel oil tank (the pipes were removed) and strong oil fumes inside our home. As a result, our dog and cat became ill within a few hours. Upon receiving and spraying the VaporRemed, the fumes quickly disappeared and the animals recovered. ...

  • H2S Oxidation and Sulfur Recovery

    Lubrizol’s facility in LeHarve, France produces a lube oil additive via a batch reaction that uses elemental sulfur as a reactant and produces H2S as a byproduct. Lubrizol selected Gas Technology Products LO-CAT® II Hydrogen Sulfide Oxidation Process to sweeten H2S emissions and recover sulfur. The LO-CAT II system was chosen for its ability to handle the process variation in H2S ...
