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:

With the recent rapid advancement of technology, user equipment has become more and more complicated, diversified and faster. This has been imposing an increase in engineering costs and increasingly many users require devices facilitating customization and the reuse of past resources (legacies).

Overview:

Latest field devices have not only various self-diagnosis functions but also process-interface-diagnosis functions such as valve diagnosis of valve positioners and impulse line blockage detection of differential pressure transmitters. The YVP valve positioner can easily perform initial tuning, parameter adjustment, trend monitoring, and valve diagnosis, by using the ValveNavi YVP management software.

Overview:

Due to emerging competitors from the rapidly growing countries such as India and China and the global economic downturn triggered by the Lehman shock, many companies in the process industries are struggling to survive the severe global competition.

Overview:

The operation and monitoring functions of a plant control system are important means of understanding the condition of the plant and how it operates. Traditionally, user needs for the system focused on such features as increased operability and durability. As a result, these functions were developed for a dedicated machine in the form of dedicated human-machine interface software.

Overview:

Honeywell and Yokogawa have both been producing Distributed Control System (DCS) platforms for decades, and both are very active in this area. In 1975, Honeywell introduced its TDC2000 platform and Yokogawa brought out CENTUM. These two competing systems emerged from a similar place, oil refining and petrochemical industries, so they started out with similar basic concepts and use cases in mind.
