Customer's Voice
“We cannot imagine operating our plant without Yokogawa’s full-replica simulator.”
Nguyen Khac Son, CEO of Pha Lai Thermo Power Joint Stock Company, a subsidiary of the biggest power producer in Vietnam, Electric of Vietnam (EVN), said, “Through simulator training, our probationary and new operators can quickly learn how to operate our 300-megawatt coal-fired unit using exactly the same operator interface as the real system. Even experienced operators can effectively learn how to deal with every conceivable accident because it’s so realistic. We cannot imagine running our plant without Yokogawa’s full-replica simulator. It is essential not only for our plant but also for operators at EVN’s other plants. In addition, many power plant operators of PVN† come here for simulator training to learn how to operate a coal-fired power plant with Yokogawa DCS. So, our simulator is used to train most operators of the biggest and second biggest power producers in Vietnam.”
*Vietnam National Petroleum Group, also known as Petro Vietnam. PVN is the biggest economic group in Vietnam and owns power plants.

- Remote data monitoring via WAN
DP Level transmitter configuration can be very time consuming. Yokogawa DPharp EJA/EJX Pressure transmitters realize reduction in man hours by smart level setup feature.
What if you could detect signs of abnormalities in bus ducts (bus bars) quickly during maintenance and inspection work and respond to them at just the right time? Yokogawa DTSX monitoring solution constantly monitors connections that tend to deteriorate over time and contributes by pinpointing abnormality locations and reducing workload of maintenance personnel, helping to ensure stability in plant operations.
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.
One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.
STARDOM field control node (FCN) autonomous controllers allow both Modbus master and slave functions to run simultaneously.
Floating-point format calculations have enabled physical quantities (in engineering units) to be used in calculations.
Industrial hydrogen fuel cells can be used to produce hydrogen and oxygen from distilled water as well as run in reverse to generate electricity. Fuel cells can also be used in conjunction with intermittent energy sources like solar or wind to provide regulated continuous energy output.
Seawater leak detection is the post-condensation water quality management processes. Damage to the ion exchange resin, which deionizes the supplied water, is also monitored during this process, and both of these applications are executed by a conductivity analyzer. (AN10D01P01-01E)
Industrial Combustion sources such as thermal cracking furnaces and, process heaters play a critical role in the process industry.
A Midwest customer is a leading salt manufacturer. They produce a variety of salt products including table salt, pool salt and industrial grade salt. This customer needed to bring data from existing Yokogawa DAQSTATIONS into their Delta V system.
Tantalum Capacitors are electrolytic capacitors that use a material called tantalum for the electrodes. Large values of capacitance similar to aluminum electrolytic capacitors can be obtained.
A major power company in the Southeast decided to replace its hydrogen gas detection system. The current system was unsupported by the manufacturer and failing. The new system would need to duplicate the functionality of the old to minimize the training and impact on the operators. Yokogawa was asked to facilitate the project.
MVAdvanced is used on the test bench for a variety of temperature measurements during product development. The products are judged to have passed the temperature stabilization test for the first time when the measured temperature stays within a determined range and time frame preset by the user.
In process operations, there are instances where ratio control is required to maintain a consistent blend of two or more components. This control action is used in chemical, food & beverage, and pharmaceutical batching operations.
YS1000 Series instruments can accept ONE direct input when a signal conditioning option is specified. The direct input replaces one of the non-isolated 4 to 20mADC (using a 250Ω shunt resistor) or 1 to 5VDC inputs. YS1700 can accept five analog inputs. YS1500 can accept four and YS1310, YS1350, YS1360 can accept two analog inputs. In all cases, one input can be signal conditioned.
Most SLPC and YS170 controllers in the field contain a custom program stored on an EPROM in the case of the SLPC and in NVRAM in the case of the YS170. When upgrading from an SLPC or YS170 to a YS1700, it is necessary to either rewrite the program in YS1700 language or convert the program from SLPC or YS170.
Yokogawa enjoyed strong sales of its line of YS80 instruments from their inception in 1980 to discontinuation in 2008. Thousands of the SLCD (single loop controller) and SLPC (programmable controller) where sold in the United States. As parts began to become scarce, the next generation of high-end controller was designed and released as the YS100 series.
Both centrifigal and axial compressors cannot be allowed to operate below the surge limit of the operating conditions. The machinery may be exposed to excessive stress and vibration. If the discharge flow demand is less than the compressor surge limit, some of that flow must be vented or recycled to the inlet to stay above surge.

Fossil fuels have long been used as a heat source in power generation. Coal is one of the more common fuels, but environmental concerns have led to a great deal of time, effort and money being spent on the reduction of pollutants resulting from the use of coal.
Industrial facilities where power and steam is produced (i.e., Cogeneration) exhibit a very good potential for real time monitoring and optimization using Visual MESA Energy Management System.
Based on our extensive experience, overall benefit in the range of 2% to 5% of the total energy cost can be achieved. Expected project payback is always less than one year.
Visual MESA was successfully applied to many industrial facilities worldwide, several of them operating steam and power generation networks of different complexity and capacity but all with energy cost savings.
Chemical plants, nuclear power plants, and large-scale engineering systems including railways and aircraft must be operated at least safely enough so as to not affect the surrounding environment. Furthermore, it is apparent that even only one accident or problem becomes the target of fierce criticism from the general public, as seen in the response of people to the accident of the Fukushima I Nuclear Power Plant of the Tokyo Electric Power Company and the problems with Boeing's 787 jetliners.
Recently, there is an increasing demand for operation and monitoring of all the various controllers distributed in the field on the same screens to improve plant operation efficiency. The purpose of the Unified Gateway Station (UGS) is to connect external controllers, such as the STARDOM's FCN/FCJ autonomous controllers and other vendors' controllers, to the CENTUM VP integrated production control system and to operate and monitor those external controllers on the Human Interface Station (HIS) screens, the operation and monitoring screens for the CENTUM VP.
We have developed the "Econo-Pilot" energy-saving system for water pumps, which reduces the power consumption of motors for water supply. In the energy-saving control field, the conventional method used is that of constant pressure control of the water supply with inverters.
The engineering phase holds the largest ratios in control system configuration in terms of both time and money, so improving engineering efficiency is one of the biggest issues when it comes to system integration. In the STARDOM, Application Portfolios (APPF) are devised to dramatically slash engineering costs and increase software reliability.
Yokogawa Electric Corporation, one of the leading manufacturers of industrial recorders, put the DAQSTATION DX series stations on the market in 1999, which added information processing and transmission functions to conventional recorders.
Yokogawa has been offering the EXA200 series two- wire liquid analyzer for processes since 1990. This analyzer has been used in various fields including the quality control of raw materials in process plants in the electric power and petrochemical industries, reaction management of products, quality control in waste water facilities, and quality monitoring of river water and tap water.
