Overview:

Steam is still one of the most popular methods of providing an energy source to a process and its associated operations. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality.

Application Note
Overview:

Level transmitter configuration can be very time consuming. DPharp transmitters with advanced software functionality eliminate this time consuming task. With maintenance shops getting smaller, finding equipment that allows us to do more with less becomes a priority.

Application Note
Overview:

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.

Application Note
Overview:

Recently, air pollution legislations such as the Clean Air Act to reduce the amount of air pollution are increasing worldwide. The Clean Air Act address numerous air quality problems. One of these problems is acid rain caused by sulfur dioxide and nitrogen oxide emissions from fossil-fueled power plants and other industrial and transportation sources.

Overview:

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.

Industry:Chemical, Power

Overview:

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.

Overview:

Cogeneration systems that improve overall energy utilization by simultaneously generating electricity and heat from a single fuel source have been in the news a lot recently. Distributed generation equipment, a type of cogeneration system, is driven by a gas or diesel engine. Advantages of the gas engine, which is widely used, include high thermal efficiency and secure fuel supply.

Overview:

A package boiler operates more efficiently if the oxygen concentration in the flue gas is reduced. Optimizing air intake for boiler operation requires continuous measurement of the oxygen concentration in the flue gas.

Overview:

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.

Overview:

Exhaust gases from a pulverized coal-fired boiler contain a large quantity of dust. To prevent this from being released into the atmosphere, an electrostatic precipitator (ESP) is used to remove the dust. To maintain the collection efficiency of an ESP and prevent dust emissions, abnormalities must be detected immediately. 

Overview:

Yokogawa ensures a reliable heat and CO2 transfer system by using the standard GPRS protocol. The exclusive use of webbased technology enables the market gardeners to go online to order heat and CO2 and view information.

Overview:

This paper introduces the ADMAG AXR 2-wire magnetic flomwmeter solution for chilled water application in air conditioning unit.

Overview:

The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement. The TDLS200 Laser Analyzer is the solution to all these problems.

Overview:

Industrial Combustion sources such as thermal cracking furnaces and, process heaters play a critical role in the process industry. Because the large amount of fuel such as gas or fuel oil which is consumed in these processes, their combustion efficiency directly affects the performance and operational costs of the production facilities.

Overview:

In a pulverized coal-fired boiler of a large power plant, an oxygen analyzer is essential for combustion control. A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust).

Overview:

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.

Overview:

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.

Overview:

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.

Overview:

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.

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. 

Overview:

Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.

Overview:

Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.

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.
