  • Several waste gas streams: Highly contaminated oxygen-free waste gas, and medium waste gas stream - Case Study

    Example: Chemical industry Similar tasks: Petrochemical and pharmaceutical industries A producer of synthetic rubber creates a medium waste gas as well as a highly contaminated oxygen-free waste gas which contains primarily low hydrocarbons. The main waste gas stream is purified in a regenerative thermal oxidiser (RTO), while the oxygen-free waste gas passes through ...

  • 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 ...

  • Treatment of Oily-Waste Process Streams

    Standard oily-wastewater remediation relies on API 650 for oily-wastewater separation (O/W/S) treatment using gravimetric lagoon separation, then reprocessing the recovered floatable slop oil, followed by chemical flocculation, then reprocessing the recovered oily sludge, followed by dissolved air flotation (DAF), then using holdingpond clarification of supernatant wastewater, before ...


  • How Do You Choose the Best Reverse Osmosis and Nanofiltration Membrane System for an Industrial Facility?

    As global demands for clean water increase, more and more industrial facilities are looking toward membrane filtration solutions, such as reverse osmosis (RO) and nanofiltration (NF), to help manage intake, process, and waste water treatment. Using membrane filtration can help your facility reuse wastewater and virtually eliminate discharge fees, and depending on the industry or required use, it ...

  • 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 ...

  • Several waste gas streams: Short, high concentration peaks and a constant medium concentration - Case Study

    Example: Production of synthetic resin Similar tasks: Chemical industry, batch processes in the pharmaceutical and plastics industry The production of high quality synthetic resin for marine paints and varnishes, coatings and repair materials, involves different waste gas streams. In addition to waste gas with a medium level of contamination, there is also a highly ...

  • Quantifying the impacts of co-digesiton of waste streams with sewage sludge

    In order to slow down the impending impacts of global climate change due to consumption of fossil fuels, governments are looking at ways to develop and incentivise alternative renewable energy sources. Subsequently, the UK has imposed renewable energy targets of 15% of all energy consumption by the year 2020, but admit that – in order to meet carbon dioxide reductions of 20% by 2020 – renewable ...

  • Turning Carbon Emissions Into A Revenue Stream

    On the heels of the EPA’s new carbon rules proposed by President Obama on June 2, I wanted to take a closer look at a potential disruptive technological breakthrough: taking CO2 waste streams and turning them into saleable, value-added feedstocks. Certainly, the deployment of renewables, energy efficiency, smart grid, and energy storage technologies offer some of the most cost-effective ...

  • Rapid Gas Chromatographic Technique for the Determination of HYDROGEN in Reactor & Process Streams and Fuel-Cell Systems

    HYDROGEN is the most prevalent Element in the Universe… the “essence of Star Stuff” according to the late, great Carl Sagan. It is the ultimate “clean” fuel, with WATER as the predominant waste product… though care must be taken to minimize its unfortunate tendency to cause explosions. Hydrogen is formed in Nuclear Reactors, from low-efficiency Hydrolysis, in smaller amounts from natural Bio-Mass ...

  • Biological Removal of Ammonia from Contaminated Air Streams Using Biofiltration System

    ABSTRACT Ammonia is a colorless, toxic, reactive and corrosive gas with a sharp odor. It is irritating to the skin, eyes, nose, throat, and lungs. Ammonia gas occurs in the environment naturally and is emitted by many industries and, therefore, its control is essential. Biofiltration is a new emerging technology that is being used as a control procedure. This study evaluates the use of a ...

  • Landfill waste gas abatement - Case study

    For over 43 years Catalytic Products International has designed and manufactured specialized oxidation systems for use in controlling process-related VOC emissions. The QUADRANT-NRV Series Thermal Oxidation System is designed for use with the low-volume/high-BTU waste gas stream emitted from many landfill gas purification processes. As we utilize our Venturi Burner Package to process the waste ...

  • Very large waste gas volumes with low contaminant concentration - Case Study

    Example: Electronics industry Similar tasks: Paint shops, spectacle coating, coating on the inside of cans The electronic industry produces semiconductors that generate very large waste gas streams that are only slightly contaminated. These waste gas streams are purified in rotary adsorbers. The continuous regeneration of the adsorbers generates highly contaminated ...

  • 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 ...


  • 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 ...
