Description
Description:
The ABB AO2000 LS25 is a highly specialized laser analyzer from the Advance Optima series, designed for continuous process gas analysis. This sophisticated module utilizes advanced laser spectroscopy to accurately measure the concentration of various gas components, making it a powerful and reliable tool for emission monitoring and process control in challenging industrial environments.
Application Scenarios:
In the rigorous world of industrial process control, the precise monitoring of gas composition is crucial for safety, efficiency, and environmental compliance. A major steel plant, for example, faces the constant challenge of optimizing its blast furnace operations to maximize production while minimizing energy consumption and harmful emissions. The AO2000 LS25 provides an elegant solution. By installing the AO2000 LS25 to continuously monitor key gas components like carbon monoxide and methane in the off-gas, the plant can gain real-time insights into the combustion process. This allows operators to make immediate adjustments to air-fuel ratios, ensuring complete combustion and preventing the release of dangerous unburnt gases. This proactive control not only enhances safety and reduces waste but also helps the facility adhere to stringent environmental regulations, showcasing the AO2000 LS25‘s direct impact on operational excellence.

Technical Principles and Innovative Values:
- Tunable Diode Laser Spectroscopy (TDLS): The AO2000 LS25 employs TDLS, a highly specific and sensitive measurement technique. This principle involves a laser that is tuned to a specific absorption line of the target gas. Because each gas has a unique absorption signature, this method provides unparalleled selectivity, eliminating cross-sensitivity issues common with other technologies and ensuring accurate readings even in complex gas mixtures.
- In-Situ Measurement Capability: Unlike traditional analyzers that require a separate gas conditioning system to draw a sample, the AO2000 LS25 is often used for in-situ measurements. This means the analyzer is placed directly in the process stream (e.g., a flue gas duct), eliminating the need for complex and high-maintenance sample handling systems and providing faster, more representative data.
- Simplified Calibration and Reduced Maintenance: A key innovation of the AO2000 LS25 is its automatic calibration function. The analyzer can perform self-checks and calibrations without requiring manual intervention or the use of calibration gas bottles. This significantly reduces operational costs and maintenance effort, making it a highly reliable and low-TCO (Total Cost of Ownership) solution.
Application Cases and Industry Value:
A large chemical plant specializing in ammonia production faced challenges with emissions monitoring. They were required to continuously report on ammonia levels in their stack gases to meet local environmental standards. Implementing the ABB AO2000 LS25 system allowed them to replace their aging, high-maintenance analyzer. The new laser-based system provided continuous, highly accurate measurements with a much lower detection limit. As a result, the plant was able to fine-tune its production process to reduce ammonia slip, saving money on raw materials and avoiding potential regulatory fines. The plant manager praised the system’s “unprecedented reliability and ease of use,” noting that it had “virtually eliminated unscheduled downtime for maintenance on the gas analyzer.”
Related Product Combination Solutions:
The ABB AO2000 LS25 is part of a comprehensive modular system and can be combined with other components for a complete solution:
- AO2000 Central Unit: The main system housing that the AO2000 LS25 module plugs into. This unit provides the power supply, display, and control functions for the entire system.
- Uras26: An infrared photometer module used for measuring gases like CO2, N2O, and CH4. It can be combined with the AO2000 LS25 in the same central unit to create a multi-component analysis system.
- Caldos25: A thermal conductivity analyzer module, ideal for measuring gases like H2 or Ar. It can complement the laser analyzer by providing data on other key components.
- Magnos27: A paramagnetic oxygen analyzer module, essential for applications requiring continuous oxygen concentration monitoring. It works synergistically with the AO2000 LS25 in combustion control and inert gas monitoring systems.
- Advance Optima SCC-C: A sample gas cooler, used when the gas needs conditioning before being analyzed by the module. This is particularly relevant for high-temperature applications.
