All environmental preservation activities on the production site starts from correct measurement of environmental data for reducing greenhouse gas, that serves as a vital parameter for optimal control.

The measurement of environmental data is useful if it accurately shows the amount and the composition of the heat-trapping gas such as CO2 as well as the physical quantities such as temperature, pressure, and flow, in real time in the production process.




Zirconia Oxygen Analyzer
Yokogawa’s zirconia oxygen analyzers are used for combustion monitoring and control in energy-consuming industries. For example, they are used in various combustion facilities such as incinerators and boilers. Combustion monitoring and control using the analyzer also contribute to a lowering of CO2, SOx, and NOx emissions by allowing for more complete combustion, thus preventing global warming and air pollution.

Pressure Transmitter
The DPharp EJX series pressure transmitter is a new model of the DPharp series. More than 1.2 million units of the DPharp series are operating all over the world. They are used to measure flue gases and the exhaust gas pressure. The measured data help an industrial user to keep its plant operation environmentally friendly.

TruePeak tunable diode laser (TDL) analyzer
Yokogawa’s TruePeak tunable diode laser (TDL) analyzer is used to monitor and control of various gases for combustion control by heating furnaces and boilers. Combustion monitoring and control using the analyzer also contribute to a lowering of CO2, SOx, and NOx emissions by allowing for more complete combustion, thus preventing global warming and air pollution.

Infrared Gas Analyzer
The infrared gas analyzer continuously monitors the fractional concentration of four elements from NO, SO2, CO2, CO, and CH4 and maximum five elements by adding O2.
 The monitored values become environmental management data by comparing them with the environmental regulation in each country, and help industrial users to keep their plants environmentally friendly.

Magnetic Flowmeter
The ADMAG magnetic flowmeter measures the amount of the fluid that flows inside pipes. The flow quantity of the clean water and the drain flow quantity and other factors are correctly measured. An industrial user of the magnetic flowmeter can keep its plant to operate environmentally friendly thus contributing to prevention of global warming.

Turbidity Analyzer
Yokogawa’s turbidity analyzer is a water quality measuring instrument that adopts a different measurement method depending on the application. It is used to measure turbidities of drinking water, sewage water, etc. thus contributing to preservation of environment.

Analyze waste to confirm whether production facilities have realized their planned capability, and whether the amount of energy use has balanced the quantity of production.










The Exaquantum Product Family
Integrated information systems including Exaquantum product family contribute to environment preservation by presenting plant information database and analyzing it, to execute the environmental preservation action plan.

Paperless Videographic Recorders
The paperless recorder is further evolving. It is environment-friendly from the time it is produced. Even if you start from small-scale instrumentation, these recorders help you efficiently manage the environmental measurement information in a wide area using web technology.

CAMS for HIS, Consolidated Alarm Management Software
Alarm management is a key to avoid potential safety or environmental incidents due to alarm overload. CAMS captures critical alarms during plant upsets, and not be overwhelmed by nuisance alarms. It gives operators more time to focus on process.

InfoEnergy
Energy-saving support system, InfoEnergy, is a distributed energy management system (EMS) which can be extended step by step as required. A web browser makes the integrated monitoring of the EMS installed in the distributed autonomous type controller.
The system also mounts the facilities management and the energy-saving controlling functions, and supports waste detection in your operation. It supports maintenance and management of the energy-saving equipment.

Reduce energy waste. The ultimate goal of energy conservation is to deliver energy where it is required, when it is required, and in the required amount. We call this Energy on Demand method.

The introduction of fully digital control system makes considerable work space free in plants and drastically increases work efficiency. By making use of digital information technology, we are able to introduce an IT-oriented advanced control technology to maximize productivity and reduce energy consumption.



Exasmoc, Advanced Process Controller
Reduction of energy consumption is one of major environmental conservation activities. Exasmoc minimizes energy consumption with its multi-variable control function to optimize the future behavior of the concerned equipment. Especially in an ethylene cracking furnace unit, Exasmoc improves separation thereby reducing recycle flow to furnaces and minimizing fuel gas or electric power consumption.

Exapilot, Best Practice Pilot
Skilled operators have enough experiences and expertise to operate target manufacturing plant safely in environment-friendly manner. Exapilot helps those operators build in their operation knowledge into control systems, so that junior operators can perform the same quality operation without fail making use of the stored knowledge.

CENTUM VP
In 1975, right after the first oil crisis, Yokogawa introduced the world first micro processor based distributed control system, or the DCS, that used only digital signals to control operations.
 CENTUM CS 3000 R3 Integrated Production Control System has the very high availability of seven nines, or 99.99999%, realizing stable operation for a plant over a long term. It means that the waste and accident of a product by plant shutdown can be prevented. And it contributes to improvement in energy efficiency ratio through optimum operation of the large-sized plant. CENTUM VP succeeds to its DNA positively.

Safety Instrumented Systems
Prosafe-RS Safety Instrumentation System protects environment by preventing a plant accident, and supports the optimum operation by integrating with the CENTUM CS3000 R3.
