Integration of Real-time Utility Monitoring with a DCS
The discharge of improperly treated industrial chemicals and fuel gas can have a major impact on the environment, posing a serious threat to public health. Concurrent with the global growth of manufacturing operations to keep pace with market trends, many countries are taking measures to deal with environmental problems.

Measurement of pH of Leachate
The leachate interfered with stable pH measurement and required frequent cleaning at least once a week. A pH meter with air jet cleaning system provides continuous cleaning and therefore can reduce maintenance frequency to once every one or two months.
Detail
Process Analyzers for Stable Long-Term Measurement
Yokogawa process analyzers can be used to measure O2 and CO at the upper end of a kiln or at the outlet of a flash furnace. They are expected to provide stable, long-term performance even under harsh process conditions.
Detail
Dust Monitoring of Exhaust Gases
The exhaust gases at a cement manufacturing plant contain a large amount of dust. To prevent dust from being released into the atmosphere, an exhaust gas treatment device such as an electrostatic precipitator (ESP) is used to remove the dust.
