Enabling Technologies

CENTUM VP Integrated Production Control System

The CENTUM VP integrated control system secures interruption-free “uptime only” plant performance for optimal productivity and profitability in the renewable energy field.


FAST/TOOLS SCADA

The FAST/TOOLS package optimizes performance for renewable energy applications. It ensures high availability and performance and supports online configuration.

 

Customer Challenge

Reducing the emission of CO, NOX, dioxins, and other substances into the atmosphere by burning off residual gas components in the stack gas

Solution

Yokogawa gas analyzers measure the oxygen concentration in the stack gas so that adjustments can be made in the O2 supply that will improve combustion efficiency and burn off more residual gas components.

ZR Series Zirconia Oxygen Analyzers

Yokogawa’s zirconia oxygen analyzers are used for combustion monitoring and control applications and are relied on by a wide range of industries to optimize combustion and reduce NOX emissions.


TDLS200 Laser Gas Analyzer

The TruePeak TDLS gas analyzer relies on a proprietary peak area integration method and is ideal for in-situ analysis in harsh process environments. It significantly improves the efficiency of boiler operations.


SG750 Stack Gas Analyzer

The SG750 stack gas analyzer consists of an infrared gas analyzer unit, a zirconia oxygen analyzer unit, and a sampling unit, and can simultaneously measure up to five components: NOX, SO2, CO2, CO, and O2.

 

Customer Challenge

Minimizing the difference between the planned load and the actual amount of waste loaded into an incinerator. The actual amount depends on the waste type and condition.

Solution

The human interface station (HIS) for the Yokogawa CENTUM distributed control system (DCS) displays a trend graph in which curves are plotted indicating the planned and actual (cumulative weight) incinerator load. If there is any divergence from the planned load, the operator can adjust the stoker speed accordingly.

Waste to Energy Process

Waste delivered to an incineration facility is dumped into a pit and then transported by crane to the incinerator. The waste is burned and the remaining ash is collected at the bottom of the incinerator. The combustion heat can be used in district heating systems, water heating systems for swimming pools, and other applications, as well as to heat a boiler that produces steam. The steam drives a turbine that generates electricity. The exhaust gas passes through a cooling tower and dust collector before being discharged through the stack.

Overview:

Facing serious environmental problems for the whole earth, clean energy using solar, wind, geothermal, tidal, etc... to reduce CO2 emissions is an inevitable matter. Renewable energy providers need economical/reliable/efficient solutions. Yokogawa provides a reliable data acquisition system with high accuracy for measurement and control instruments.

Overview:

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.

Overview:

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. 

Documentación Técnica
Overview:

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.

Overview:

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.

Overview:

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.
