Optimize petrochemical production with reliable automation solutions that improve safety, efficiency, and profitability.

Preserve every drop with reliable solutions for drinking water, wastewater, industrial water, and desalination.

Reducing emissions for home grown energy.

Generating electricity despite the weather.

• Natural-gas processing
• Control dew point of natural gas stream
• Separate natural gas liquids for sale and distribution 

Ammonia producers are faced with rapid growth combined with many older control systems. Growth is driven by global demand for fertilizer and supported by cheap and plentiful shale gas.

Desalination is the removal of dissolved salts from seawater, mineralized groundwater, brackish water from inland seas, and municipal wastewater.

The goal of drinking water treatment is to produce clean, safe, and potable water that meets regulatory standards and is suitable for drinking and other domestic uses.

Industrial water is essential for production and process water, manufacturing facilities, feed water for boilers and cooling towers, food & beverage processes, and other treatment needs.

Mining operations produce valuable minerals or geological materials from the Earth. Economical recovery often requires high throughput and high availability of the process with low operation costs, and stringent safety and environmental regulations.

Safety-instrumented architecture with 99.999% availability safeguards reactors and staff across decades-long plant lifecycles.

Reliable monitoring and control of hydropower plants around the world.

Harvesting around the clock energy from tropical waters.

Yokogawa's production control systems are operated at 54 LNG receiving terminals around the world, and 2/3 of the terminals in Japan. Yokogawa contributes to stable and efficient gas supply at LNG receiving terminal through the total process, loading, storage, regasification, and metering.

Improve chemical plant safety, reliability, efficiency, quality, and sustainability with Yokogawa measurement, control, optimization, digital, and lifecycle solutions.

Yokogawa has been engaging in LNG automation by supplying the latest sensors, analyzers, control and information systems for more than 50 years since LNG was first imported to Japan. Yokogawa is one of the biggest automation suppliers to the worldwide LNG supply chain, liquefaction, transportation, and regasification.

The paper and pulp industry is highly competitive and must meet ever-changing market needs. Yokogawa helps realize energy-efficient plants which are globally sustainable.

Yokogawa helps bulk chemical producers improve safety, reliability, efficiency, and profitability with lifecycle automation solutions.

Highly reliable Yokogawa production control systems, which have been proven thorough extensive global projects, are installed in 76 trains of LNG liquefaction facilities and continues to improve the safeties, efficiencies and productivities. Also, Yokogawa contributes to maximize the revenue by enabling the efficient operation to the complex liquefaction process via APC (Advanced Process Control) license with consulting.

In the ever-changing marketplace, refineries are seen not only as crude processing units but also as profit centers. At the same time, there is a keen awareness of the need for safety at such facilities. A total production solution that encompasses planning, scheduling, management, and control is required to achieve long-term goals for profitability, efficiency, and environmental protection. With years of expertise in the automation field, Yokogawa can bring you affordable total solutions for improved operability and a cleaner world.

The rigorous demands of Chlor-alkali production require accurate, reliable instrumentation that provides all required measurements.

The increasing demand for petrochemical goods, coupled with the quest for cleaner energy sources, contributes to the surge in methanol demand.

The FU20 and FU24, all-in-one pH and ORP, sensors show how Yokogawa applies the motto "Simple is best" to sensor technology.

Cation differential pH and ORP sensors

The heart of a pH measuring loop is the electrode system. Yokogawa has designed a wide range of electrodes to ensure this heart keeps beating under the most severe conditions.

Superior accuracy and stability, even after repeated sterilizations

Achieving accurate and reliable readings using a traditional pH analyzer is challenging, however with the right equipment stable and accurate pure water pH measurements can be accomplished. Yokogawa's specialized bellomatic pH sensor is proven best solution for high purity water applications. For those individuals that do not like the maintenance of refilling sensors, then the FU24 which incorporates the successful patented bellow system in an All-in-one body is the ideal solution.

Optimize field maintenance, calibration, and system configuration

Ensure fluid process operations
