Eraring Power Station, located just north of Sydney, is one of the largest power stations in Australia, comprising four 660MW coal-fired units. The power station has operated reliably since 1981. To ensure continued reliability for the next few decades, Eraring Energy, the owner of the power plant, decided to replace the original hard-wired control equipment with a modern integrated control and monitoring system (ICMS).

At the age of approximately 30 years the plant underwent $A 72 million technology upgrade in 2001, to improve operating reliability and performance. Macquarie Generation, Yokogawa Australia and Ralph M Lee concluded an alliance agreement to supply and install the replacement control system at Liddell.

The customer has successfully brought online a greenfield 800 MW supercritical power plant, using a Yokogawa full-replica plant simulator to ensure a fast and smooth plant commissioning process.

The construction of Tuas Power Station started in the mid 1990s. The plant has steadily grown to be a significant player in the competitive Singaporean electricity market.

Con talleres de mantenimiento cada vez más pequeños, la búsqueda de equipos que nos permiten hacer más con menos se convierte en una prioridad.

Recientemente, las legislaciones de contaminación del aire, como la Ley de Aire Limpio para reducir la cantidad de contaminación del aire están aumentando en todo el mundo. La Ley de Aire Limpio aborda numerosos problemas de la calidad del aire. Uno de estos problemas es la lluvia ácida causada por las emisiones de dióxido de azufre y las emisiones de óxidos de nitrógeno de las centrales eléctricas alimentadas con combustibles fósiles y otras fuentes industriales y de transportación.

In flue gas desulfurization systems that use magnesium hydroxide (Mg(OH)₂) slurry, the consumption of the desulfurization agent (Mg(OH)₂) is controlled by using online pH analyzers. A great concern in the pH measurement is heavy staining of the pH electrodes by the Mg(OH)₂ slurry. To ensure accurate measurement, frequent cleaning of the electrodes with an acid is required, adding to both maintenance workload and cost.

In limestone-gypsum flue gas desulfurization systems, the consumption of a desulfurization agent (lime) is controlled using online pH analyzers.

Current trend for increasing mercury awareness throughout the public sector has caused the government to take action. Recently, the Environmental Protection Agency (EPA) has focused their efforts on controlling mercury levels produced in various coal fired power plants. Based on information from several case studies, the EPA developed the Mercury and Air Toxics Standards to cut back mercury emissions. The most popular technology utilized by coal plants to meet the new standards is a scrubber which cleans the off gas from the combustion process. ORP sensors can further monitor the effluent from these scrubbers to ensure optimal mercury emission levels are achieved. By closely monitoring the mercury concentrations in the effluent, plant managers will be able to easily confirm their plants are meeting the EPA's standards.

The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.

Power plants concerned with lowering NOx emissions are making tremendous changes to accommodate EPA regulatory requirements. A substantial number of these changes include the expansion and upgrade of the plant combustion oxygen measurement equipment. There is a striking relationship between the number of NOx reductions projects and the sales quantity of insitu oxygen detectors.

From engineering to installation, commissioning, operations, and maintenance, FOUNDATION fieldbus offer significant cost reductions of 30 percent or more versus conventional analog systems. Many of these cost reductions come from the advanced functions that fieldbus offers versus analog technology.

The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.

In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action. 

Yokogawa ha recorrido un largo camino en hacer que su mensaje sea claro en el mundo de la automatización de procesos. El año pasado, la compañía se embarcó en una campaña global de marketing a gran escala para que los clientes conocieran el enfoque de la compañía en la confiabilidad del sistema, su seguridad, constancia y durabilidad. Denominado "Vigilancia", la campaña creó un mensaje unificado para la empresa y en gran medida ayudó a aumentar la difusión de la marca Yokogawa y la filosofía de la empresa.

Los usuarios finales de procesos automatización están bajo más presión para hacer más con menos. La situación económica actual hace que muchos proyectos de capital de automatización estén en espera. Con los presupuestos de capital más limitados que nunca, los usuarios en lugar de enfocarse en los presupuestos de operaciones (en donde también la reducción de costos es una preocupación clave), o en las inversiones de automatización con un rápido retorno de inversión.

In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.
