  • Air pollution control (APC) equipments for power plants

    We live in a power dependent world. Almost every human activity requires energy and many of them require large amounts of energy. For example, the production of metal from ore is one of the most energy-consuming productions available due to the high melting point of metal. Depending on the type of energy powering the production, a release of emissions of polluting particles will be inevitable without our technology. In addition come emissions from production as the power is used for.

  • Secundary air flow measurement for power generation industry

    Secondary Air Flow Overview: The need for accurate, repeatable & reliable combustion air measurements in power generation plants is critical to efficient operation and safety throughout the entire facility and processes. Accurate secondary air flow measurement to the burners is critical for maintaining the proper air to fuel ratio, result­ing in more complete and stable combustion, better performance and lower emissions. Coal-fired power plant applications pose a number of challenges to obtaining these critical flow measurements including large ducts, limited metering runs, poor velocity and temperature profiles, vibration and high temperatures.

    Gas monitoring instruments and systems for stack testing

    Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives and regulations set. Two major parts of this on-going quality assurance cycle are the QAL2 and AST procedures. A test laboratory performs tests on the systems on-site, and determines whether the systems fulfill the set requirements or not.

    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.

    NH3 Monitoring in Air

    NH3 (Ammonia) is a colorless gas with a distinctive pungent smell. Ammonia monitoring is essential in coal-fired power plants, where NH3 is used to reduce NOx emissions. The ammonia consumes all of the NOx, but its high concentration that is needed for these purposes also starts reacting with other things and in the process can clog up filters and cause premature failure of expensive SCR equipment and pre-heaters. Not to mention that these high levels create an irreparable damage to the environment.

  • Biomass Drying

    Biomass produces a cleaner, renewable energy, reducing harmful carbon dioxide emissions, all while creating lower operating costs for power plants. Biomass, the by-product of pulp and paper, agriculture, and municipal sludge, is perhaps the oldest source of renewable energy on Earth. Biomass' use in energy production is currently growing worldwide at an exponential rate.

  • Measurement solution for CO2 capture by amine absorption

    The act of capturing and storing CO2 produced from large scale combustion plants such as power stations is becoming more and more favourable and feasible. One of the most common post-combustion CO2 capture methods is by absorption. The absorption plant can be added on to the existing combustion process, with the flue gas first passing through an absorption column where the CO2 reacts with an absorber. Amines of different types are used as the absorber. An amine CO2 capture plant can capture as much as 90% of the CO2 emitted from the power station and so has a real benefit for the environment. Having said this, care needs to be taken to ensure that amine emissions themselves are monitored, managed and prove no extra damage to the environment. Research is on-going to develop new amines or mixtures of amines to reduce emissions. The most common absorber in use in today’s first generation of industrial pilot plants is Monoethanolamine (MEA).
