Waste incineration is a complex area. The mix of waste, moisture content, temperature of the waste, surrounding air and a variety of other factors interact and affect which residues are formed. Combustion entails often a gas consisting of heavy metals, sulfur oxides, chlorides, dioxins, etc. It is extremely important with a proper handling of the gas and the task often requires a mixture of wet and semi-dry treatment. EnviBAT offers equipment that brings particle levels down to extremely low levels, which guarantee...
From a regulatory standpoint, the industry is divided into a number of categories: commercial/industrial solid waste incinerators (CISWI), municipal waste combustors (MWC), hospital/medical/infectious waste incinerators (HMIWI), hazardous waste combustors (HWC), sewage sludge incinerators (SSI), and other solid waste incinerators (OSWI). While each sub-category is subject to differing environmental regulations, all can benefit from evaluating their air pollution control requirements.
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently listed as priority air pollutants.
Continuous Emissions Monitoring Systems (CEMS) are used to measure flue gases from stationary sources at a wide variety of regulated industrial facilities, including power plants, petroleum refineries, petrochemical plants, waste incinerators, pulp and paper producers, and many others. The types of air pollution measured from these sources vary widely based on the industry and process, and many are regulated by government agencies around the world.
In calcination processes, solid intermediates and products are regularly handled in fine powder form. (ex: kaolin or metakaulin). There is a need to separate these very fine powders from the exhaust streams of calciners, fluid bed dryers or incinerators, often at critical temperature conditions
Cooper Environmental's Xact® 640 has the unique ability to generate high time resolution metals measurement in stacks. This unique capability has the potential to qualify as a substitution for the combination of a Hg/ PM CEMs application as well as the potential for a pollution control system feedback loop that could result in the reduction of pollution control consumables. Our systems have been site certified for compliance measurements at hazardous waste incinerator and secondary lead smelter sites.
Waste incinerators, cement plants and power plants need good and reliable measurements of total gaseous mercury. The measurement of total gaseous mercury is a challenge due to chemical reactions and contamination. The installed systems will often require a lot of maintanence still not giving reliable results.
For industrial and municipal treatment plants; Chemical scrubbers, biological towers and adsorption systems to remove hydrogen sulfide, mercaptans, other organic sulfur compounds and ammonia from digesters, pump stations, ponds, grit and screening works, sludge filter presses and dryers. Special Wet Electrostatic Precipitator for sewage sludge incinerators. Stripping ammonia and other volatile compounds. Decarbonization removal of carbon dioxide from wastewater.
Application: PPS (Ryton) Filter Bags are widely used in coal-fired boilers, waste incinerators, coking furnaces, kiln furnaces,Biomass Furnace ,chemical dry process of flue gas cleaning processes, also using, carbon black, powder collection, pneumatic conveying, cement industry, and more. When due to chemical attack and hydrolysis causes, Aramid cannot be used, PPS (Ryton) Filter Bag can be substituted.
Government and environmental groups are forcing industries with medium to high VOC exhausts to reduce emissions by as much as 98%. Incineration using pollution control devices such as oxidizers and flare stacks is one way to bring the exhaust emissions in line with the regulations. Capturing and reusing solvent in a solvent recovery system is another way.
The consumption of scrubbing material in a scrubber is related to the mass flow of acid gases. Hydrogen chloride (HCl) and sulphur dioxide (SO2) are the major acid gases in an incinerator. By measuring the mass flow of SO2 and HCl in the raw gas going into the scrubber, it is possible to calculate the required quantity of scrubbing material.
For large combustion plants and power plants we offer the DCEM 2100 particulate monitor. This monitor is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It offers outputs in Transmission, Opacity and mg/m3 (when calibrated against a Standard Reference Method). The DCEM 2100 offers real-time zero and span calibration and an efficient air purge system to prevent optical contamination.
Many large combustion plants are now required to monitor mass emissions of major pollutants and to do so requires an accurate measurement of stack gas velocity. The VCEM 5100 is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It has several key advantages, firstly the sensors optics are not in contact with the hot and dusty environment, the VCEM 5100 can monitor gases at temperatures exceeding 10000C and the analyser requires minimal maintenance. The VCEM 5100 can be...
Due to the continuous rise in the waste volumes worldwide it is essential constantly to seek alternatives to landfills and waste incineration: one suitable approach is bio-mechanical waste treatment. Apart from waste management, applications for air purification systems in this field range from soil remediation to sewage sludge drying in waste water treatment, as well as to the recycling of resources and their possible re-introduction.
