  • Controlling Fugitive Emissions, Part 2: Permanent Total Enclosure

    Fugitive emissions are the uncontrolled release of gases into the atmosphere. This is something that occurs regularly; in fact, it often happens when we fill our cars' gas tanks. The air being displaced inside the gas tank when it is being filled causes gasoline vapor emissions (hydrocarbons) to exit into the atmosphere in an ...

The Process The Company uses multiple scrubbers to clean out the impurities of the natural gas that they ...

  • Cleaning up by cleaning up

    Historically, some big businesses have made big messes. Greenhouse gas emissions, oil spills and unsafe water have become unsavoury but all-too-commonplace topics in the news and industry is beginning to sit up and take notice. Within the past couple of decades, businesses have been cropping up in Saskatchewan with the goal of cleaning up others’ messes - or simply keeping a mess from ...

  • 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 ...

  • LED Applications for Oil and Gas Refining and Processing

    Oil and gas processing facilities are unsafe due to the existence of hazardous compounds during operations. When addressing such issues, companies in the sector may deploy explosion proof lighting systems to prevent the ignition of sparks created from the electrical equipment. The adoption of LED technology in oil and gas refineries has helped reinforce key safety measures associated with ...

  • Santa Clara converts low concentration landfill gas to clean energy

    Landfills are an excellent source of methane-rich gas that can be used to generate renewable power. Methane is produced at a landfill as trash decomposes and can be used as fuel for a gas generator to produce electricity. Since 1986, the City of Santa Clara had successfully done this, and had been able to export power to a local utility. However, over time, gas production at a closed landfill ...

  • Waste Gas Cleaning for Road Tunnels and Underground Car Parks

    The objective of the study was to find a microbiological cleaning technique for road tunnel waste air, with emphasis on CO, NO and NO2. The chemolithotrophic CO oxidizing mixed population with an integral part of nitrifying bacteria carry out an essential step in metabolic process of NOx consumption. The immobilized microorganisms were subsequently exposing them to a constant stream of artificial ...


  • Advanced WESP designs assure superior gas cleaning performance

    Nowadays, many industries are facing formidable environmental challenges and there is a growing need for effective, economical gas cleaning and air pollution control equipment. Michael Beltran of Beltran Technologies, Inc. reports on a renewed interest in high-efficiency wet electrostatic precipitators (WESPs) and discusses their importance for controlling sulphuric acid mists and other ...

  • Process for the Separation of Gas Products from Waste Tire Pyrolysis

    In recent years, pyrolysis has proven to be an effective thermochemical process for the recycling of waste tires. After pyrolysis, three fractions are obtained:  carbonaceous solids, liquid hydrocarbons, and the so-called noncondensable gases. In this paper, the starting point is the pyrolysis reactor outlet that provides a gas stream with a temperature of 600 ...

  • Smelter gas cleaning one vessel from the quench to the drying tower

    Base metals such as zinc, lead and copper are all found in nature bound with sulphur as sulphite minerals: sphalerite (ZnS), galena (PbS), several copper minerals, silver (found as acanthite Ag2S), and, along with other precious metals. Processing of the metals invariably leads to sulphur dioxide (SO2) formation. Other metal processing, such as aluminum from bauxite ore [Al(OH)3] which contains ...

  • Food Processing: Odor Control in Edible Oil Processing

    Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen ...

  • Cleaning biogas with bacteria

    Organic materials added to an anaerobic digester commonly contain sulphur components. During the anaerobic digestion process, the sulphur is converted into hydrogen sulphide (H2S), which is absorbed by the biogas. When the biogas produced in an AD plant goes on to be combusted in a gas engine or boiler, the H2S will give off sulphur dioxide (SO2) and sulphuric acid ...

  • The Clean-Up of a Tragedy

    There's been a violent crime, a serious accident, or a suicide has occurred. The police, investigators, and paramedics have left the scene. The remains of this terrible tragedy are still there. You assume the local police, fire department, or the city has someone to take care of this, however, you are told it is up to you. You are the victim, part of the family, the property owner, or local ...

  • Cleaning mold containing surfaces

    Once a determination is made that a moldy surface can be cleaned instead of removed or demolished, what cleaning agents are effective in removing or killing the mold? Many factors influence the selection of a cleaning agent. 1). The type of surface to be cleaned: Is it porous? Hard such as cement or sheetrock? Soft, such as cloth, fabric or wallpaper? Absorbent and thick such as rugs, ...
