  • Why You Should Keep Your Air Pollution Control Technology Up To Date

    Did you know that the first crewed spacecraft to leave Earth's orbit, reach Earth's moon, orbit it, and return safely to Earth (Apollo 8) was launched into space using the Apollo Guidance Computer (AGC), which had a real time operating system which enabled the astronauts to enter simple commands to control the spacecraft? The AGC was ...

  • RTO upgrade sees significant benefits - Case Study

    A project this year to upgrade an existing RTO has been successfully completed in four areas: Increasing thermal efficiency by adding additional layers of ceramic honeycomb media into the RTO this has the benefits of energy reduction from lower gas consumption both during production & on standby. De-commissioning an old inefficient recuperative oxidiser which was attached to a single ...

    This article is about the case study of the TurbeEx® Cooling Tower in operation at a Huhtamaki U.S. pulp & paper facility. Commissioned in late Spring 2016 this TurbEx® COOLING TOWER cools process water at a Huhtamaki U.S. pulp & paper facility using TurboScrubber® fluidized packing to ensure continuous non-clogging operation even with sticky pulp & solids ...

  • Repeatability is King: Up to Tenfold Improvement

    Axetris has improved the repeatability specifications of its mass flow meters and controllers. Repeatability often more important than absolute accuracy Repeatability provides information about the precision, that is, the absolute difference between a pair of repeated test results measured by one instrument under unchanged conditions. To measure precision, the same ...

  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...

  • Scrubber Removes Grease and Particulates from Air Exhaust

    Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

  • Controlling acid gas mists

    Gas cleaning New and strict pollution regulations in metallurgical plants worldwide are restricting particulate and acid gas emissions to extremely low levels. Because of that, sulphuric acid plants are being installed to remove and utilise S02 in gases resulting from the roasting of sulphide ores, smelting of ores, and burning or regeneration of spent acid or acid sludge from ...

  • Greenhouse Gas Emissions Control

    Most of the time, people think about Greenhouse Gas (GHG) emissions with carbon dioxide, which is the most common of the GHGs. While fairly typical, carbon dioxide isn’t the only GHG U.S. Environmental Protection Agency (EPA) regulates.  Since EPA has begun regulating GHG emissions under its Clean Air Act authority, sources of emissions from others may require add-on air pollution ...

  • Advances in gas control technology in the brewery

    The use of nitrogen as a process gas, foam enhancer and flavour modifier has come to the fore over the last 10 years, with dissolved gas specifications becoming more stringent. Increasingly, marketing and consumer requirements for a targeted product identity or image have to be met, not only for taste but, perhaps equally as importantly for the consumer, ...

  • Taking Control of Gas Engine Issues

    In an effort to gain maximum engine performance and stay within the local exhaust emission limits over a wide range of engine load and ambient conditions, operators at the County Sanitation Districts of Los Angeles County’s Joint Water Pollution Control Plant wastewater treatment plant near downtown Los Angeles have installed Continental Controls Corp. ECV5 ...

  • Gas flow control method of recycling gas drilling technology

    Recycling gas drilling is a new drilling technology. The paper based on the theory of gas transient flow, a set of theoretic models of gas flow control at the export of annulus are set up in combinations of the principles of the seepage flow mechanics and the characteristics of recycling gas drilling technique. According to the basic laws which the flowing gas should comply with, the properties ...

  • Gas-assisted injection molding technical control

    The time and pressure of gas injection molding should be strictly controlled. The temperature of the molds should be stritly controlled,so that the cooling of thermoplastic in the cavity can be kept at an appropriate speed,which shall be of avail for the forming of gas cavity.So as a mould maker should be very good at the gas-assisted ...

  • Economic damage control for greenhouse gas emissions

    Future emissions of trace gases are intrinsically linked to economic growth and abatement policies, which in turn, are governed by expectations of greenhouse damages. Trace gas indices that depend upon future emissions can be calculated either on the basis of emissions scenarios, such as those devised by the IPCC, or using optimal control techniques where the trade-off between damages and ...

  • Controlling H2S Emissions from Landfill Gas

    A major US waste handling company operates a large landfill in Florida, and in 1992, when Hurricane Andrew struck southern Florida, the landfill saw a huge increase in the amount of C&D waste. Shortly after this, the levels of H2S started dramatically rising. This company evaluated several technologies for the removal of H2S, which was estimated to be as high as 5000 ppmv, with up to 2-3 tons/ ...

  • Gas Monitoring for Ventilation Control and Energy Management

    The growing demand for underground and enclosed parking and maintenance garages (resulting from limitations on land availability) has increased the awareness and need for proper ventilation and control systems. In addition, increased health and safety programs have only added to the concerns of toxic and combustible gases in confined or enclosed spaces. Historically, ventilation and make-up air ...

  • Chapter 10: Decentralised control of greenhouse gas emissions: coordination and cooperation

    In Chapter 2, we considered the difficulties of obtaining international cooperation in the control of CO2 emissions. The approach adopted in this chapter assumes there is an ‘empowered’ United Nations, as a principal, that coordinates its members (agents) toward a common goal, which makes this a team-like principal agent structure. We shall show that if at least two countries commit themselves to ...
