Controlling the world’s water resources is arguably one of the most critical issues. Water demand from industry and domestic users is set to rise throughout the industrialized world, while water supplies are finite. Legislation constantly demands improvements in potable water quality and reduces the contaminants that may be discharged. Wastewater treatment is one way to get water back. Wastewater is subjected to various treatments in wastewater treatment plants, each intended to remove contaminants and other hazardous substances from the water. The objective is to create water from sewage that is safe to discharge into waterways and won’t endanger the environment or human health. Over the last few years, Yokogawa has been applying minimized maintenance measurement systems to an industry that, more than ever, is concerned with condition-based maintenance and the integrity of the measured variable.
In any combustion process, it is necessary to monitor the inlet flow rates of fuel and air to the burner. While these flow rates provide baseline parameters to set a flame, they do not provide feedback to reveal or alert any potential concerns with the combustion reaction, such as incomplete combustion from imperfect mixing in the burner or safety risks such as fuel leaks or loss of flame. Flue gas analysis offers one approach to monitor the process and provide feedback. It is especially important to consider when firing both hydrocarbon-based and high hydrogen fuels.
Hot-wet continuous emission monitoring (CEM) measurement means analyzing the stack gas sample on an as-is basis, which ensures that the integrity of the sample, from extraction through analysis, is maintained. Keeping a good heat integrity in hot-wet measurement is very important to prevent the condensation of acid mist or water vapor.
If you work in the natural gas industry or are an industrial user of natural gas, water dewpoint is not only a quality measurement but also a big concern. Water condensate presents serious challenges and issues for your process. It is highly corrosive and will form hydrates, which are ice-like solid molecules that can block the flow of gas in pipelines. In cold weather, it will also freeze reducing the pipe pressure.
Optimizing boiler efficiency will increase your bottom line. Did you know that every 10% excess oxygen results in 1% in wasted fuel? With that in mind, Yokogawa Zirconia Oxygen analyzers have a 50-year proven success record for providing:
