    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).

  • Power Generation

    Combustion turbines A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in-between. The basic operation of the gas turbine is similar to that of the steam power plant except that air is used instead of water. The turbine shaft energy is used to drive the compressor and other devices such as an electric generator that may be coupled to the shaft. The energy that is not used for shaft work comes out in the exhaust gases, so these have either a high temperature or a high velocity. A catalyst is often used to treat these exhaust gases to comply with emissions regulations. EmeraChem has installed OEM and after-market catalyst in over 240 applications

  • 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.
