  • Axetris Sensor Field Test

    The Axetris LGDs were operated continuously for two years. After intensive laboratory testing, they went out into the field in 2015. Axetris was able to test the functionality of its sensors under real-life conditions thanks to the support of the Linth waste incineration plant. The gas concentration measuring devices called laser gas detectors ( ...

  • 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 ...

  • Comparison of Gas and Water Pycnometry of Coal Mine Wastes

    Coal mine washery wastes comprise two major components whose specific gravities differ markedly. Consequently, their specific gravity is much more variable than that of natural soils and is determined relatively frequently. The specific gravity of coal mine wastes is determined more rapidly and efficiently by gas pycnometry than by water pycnometry. However, the two methods give significantly ...

  • 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 ...

  • Liquid waste off-gas treatment - Case Study

    Application Biffa Waste Services operate a major waste disposal site at Kilsyth in Scotland where they handle many types of industrial liquid effluent. This can give rise to a range of emissions from both the tank farm and the road tanker deliveries. In addition, significant NO2 and nitric acid fume releases can arise from process upset conditions. ERG provided an emergency NO2 ...

  • Optimum waste interception in Liquefied Natural Gas processes

    This work addresses optimum waste interception and wastewater minimisation in liquefied natural gas (LNG) processes. The problem involves solvent regeneration and purification using distillation. The scope of this paper focuses on determining optimum impurities (waste) composition (accumulation) in the solvent loop while considering energy integration scenarios including pressure of the ...

  • Zero Waste - Zero Waste - Zero Waste

    The Planning Group of the Zero waste International Alliance defines zero waste as: “Zero waste is a goal that is ethical, economical, efficient and visionary, to guide people in changing their lifestyles and practices to emulate sustainable natural cycles, where all discarded materials are designed to become resources for other use.” I recently posted this question on ...

  • Waste not, want not

    Consultant Andy Ive considers solutions which not only comply but also enhance the environmental profile of today’s industrial companies. Until recently the prevailing perception in many industries, particularly those operating in emerging market areas has been that waste is an unwelcome inconvenience. The primary infrastructure of most companies was fundamentally not designed to deal with waste ...

  • Estimation of HAP Emissions from Oil and Gas E&P Operation Wastes

    Wastes generated from oil and gas Exploration and Production (E&P) operations contain chemicals that are considered as toxic air pollutants for the purpose of toxic release inventories (TRI) reports or hazardous air pollutants (HAP) under Title III of the 1990 Clean Air Act Amendments. A study was conducted to estimate HAP emissions from E&P waste management operations on a per-event basis. The ...

  • Greenhouse gas emission potential of the municipal solid waste disposal sites in Thailand

    Open dumping and landfilling are the prevalent solid waste disposal practices in Thailand. Surveys on the disposal sites revealed the presence of 95 landfills and 330 open dumps. Methane emission potential at these sites was estimated by three methods. Results of the Intergovernmental Panel on Climate Change (IPCC) method, Landfill Gas Emission model (LandGEM), and closed flux chamber technique ...

  • Biotreatment of waste gas containing pyridine in a novel rotating rope biofilter

    A novel Rotating Rope Biofilter (RRB) has been developed especially for the treatment of Volatile Organic Compounds (VOCs) at higher loadings and characterised by high volatility along with high water solubility. The RRB provides a higher interfacial area (per unit reactor liquid volume) along with high oxygen mass transfer rate, greater microbial culture stability, and consequently higher ...

  • Greenhouse gas emissions from waste management-assessment of quantification methods

    Of the many sources of urban greenhouse gas (GHG) emissions, solid waste is the only one for which management decisions are undertaken primarily by municipal governments themselves and is hence often the largest component of cities’ corporate inventories. It is essential that decision-makers select an appropriate quantification methodology and have an appreciation of methodological ...

  • Dewatering waste-activated sludge using dissolved gas-flotation followed by filtration

    After the successes of flotation of waste-activated sludge (WAS), using the new technique utilizing CO2 gas as well as using model gas (80% N2+20% CO2) in previous research because of the high water solubility of CO2 gas, the aim of this study is to develop a simple method for dewatering WAS for easier reuse and safe disposal. The paper introduces a laboratory model for dewatering WAS in two ...

  • Exergy evaluation of emitted waste gas and fuel consumption in food delivery process

    Food delivery from restaurants and fast food shops by motorbikes is one of the major modes of its distribution. We aim to investigate the environmental impact of food delivery process by motorbikes. The environmental impact was described from the viewpoint of waste gas emission and emission exergy. A university campus was selected as the test site. We extracted the number of food delivery, ...

  • 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 ...


  • Thermal waste gas purification of siliceous organic compounds - Case Study

    Example: Electrical industry Similar tasks: Electronic industry, Coating, Waste management When coating mica insulation materials, peaks of high contamination occur. The exhaust air containing organic compounds generates excess heat when oxidised in the regenerative thermal oxidiser (RTO). The properties of ceramic honeycomb blocks allow for the storage of that excess heat, for the ...

  • Case study - Upgrading highly loaded waste ponds to “Bio-Gas Banks”

    Problem: Un-covered anaerobic systems can generate significant amounts of odors and renewable energy in the form of methane. The sulfides and methane are lost to the atmosphere due to lack of an impermeable barrier. If the basins were covered, the biogas could be captured, burned and converted to electricity and odors contained. A Missouri project, believed to be the largest and most ...

  • Mercury recovery from industrial waste and toxic residues of natural gas drilling

Particularly, in the group of unburned ...

  • FTIR gas analyzers support management of fire at UK waste facility

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident.
