    Waste sorting solutions for the refuse derived fuel

    One way in which valuables within waste can be utilized is by using it as fuel. Refuse derived fuel (RDF) is a term that applies to materials with a high calorific value (typically around 18 Mega joule per kilogram) that are removed from waste streams. Beneficiaries of this material are cement kilns to power plants.

    Carbon capture and storage (CCS) applications

    Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process. In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of both nitrogen and sulfur (NOx and SOx). Next the purified gas is passed through an absorption column filled with the chemical scrubbing solvent. The solvent reacts with the carbon dioxide and selectively absorbs it from the gas stream. When CO2-rich solvent is heated, the carbon dioxide is released as a nearly pure gas.

    Compressed air, gas and vacuum solutions for water and waste water treatment

    There are many options to apply methods to avoid damaging the environment. In the case of wastewater e.g. the ventilation of the sediment tank or the pressure ventilation of biological wastewater treatment systems. The oxygen introduction is important, for deep wastewater tanks, wastewater treatment systems with standard aeration tanks or natural clarification ponds alike. If the wastewater has already entered the natural cycle, ventilating lakes and rivers prevents additional contamination. When treating drinking water, rinsing the filters with compressed air ensures that perfect water is provided and natural water reserves are not used excessively.

    Reliable Shredding Technology for Refuse Derived Fuels (RDF)

    Our shredding solutions enable you to optimally recycle waste into substitute fuels / alternative fuels and ensure high quality by producing a homogeneous granulate free of foreign objects. The goal of recycling is to use the valuable energy contained in the waste and to substitute the use of fossil fuels. During the recycling process the portions with a high calorific value are separated from the commercial and industrial waste and turned into a marketable product. Depending on the calorific value and the granular size, these fuels are used in fluidised bed combustion, cement plants and substitute fuel power plants.

    Gas monitoring instruments and systems for DeNOx process control

    In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.

    Continuous emissions monitoring in cement kilns

    Various pollutants form in the cement manufacturing process, especially when alternative fuels and waste-derived fuels are used. Typically a cement kiln using these fuels is a required to monitor hydrogen chloride (HCl). Gasmet CEM II is EN 15267-3 approved for HCl measurement in 0 … 15 mg/Nm3 range.High process temperatures result in generation of more nitrogen oxides (NOx) than in typical municipal waste incineration.

    Reliable Shredding Technology for Rubber and Tyres

    Our shredding systems generate granulate from the hardest rubber and old tyre applications for your recycling plant. Regardless of whether you want to use the granulate for pyrolysis, hydrolysis or combustion, we will customize it to exactly fit your needs. Regardless of whether rubber accumulates in the form of tyres, conveyor belts, rubberised chains or as production waste, recycling is economically efficient and makes sense from an environmental perspective. Very powerful shredders are required to recover recyclable materials from rubber waste and old tyres. Our proven and reliable 4-shaft technology is particularly suited in this regard. This system economically performs the pre- and re-shredding in just one step.

    Continuous emissions monitoring in waste incineration plants

    Waste-to-energy through incineration of waste is an effective way of producing electricity and heat, at the same time getting rid of the possibly hazardous or unrecyclable waste. The waste can be incinerated at specific WtE plants or at plants with permission for co-incineration of waste at biomass boilers or cement kilns. The waste incineration plants are, however, governed by strict emissions regulations.

    Monitoring solutions for the De-NOx plants

    In recent years the number of Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) plants for De-NOx have increased significantly. Continuous analysis of NOx prior to the de-NOx plant is often required to measure the concentration generated by the combustion process. This may be required to provide feed-forward to the Ammonia/Urea injection system and also to allow the effectiveness of the reduction process to be assessed. Continuous analysis of NOx post-reduction is required to allow the effectiveness of the reduction process to be assessed. It may also be beneficial to monitor NH3 slippage at this stage by calculating from the pre and post NOx levels if excess Ammonia/Urea is being applied.
