* Go beyond condition monitoring
While the activity of alarm rationalization is straightforward, its application can range from simple to extremely complex depending on resources and objectives. This white paper introduces two basic methodologies: Bounded or Unbounded, and evaluates the benefits of each.
Best Practices in Demand and Inventory Planning for Chemical Companies
It's a classic scenario in chemical manufacturing- struggling to coordinate the opinions of sales with manufacturing and supply chain initiatives on what, when, and where products should be produced. The lack of supply chain coordination can lead to frequent changes in production schedules, expedited shipments, excessive stock outs, poor customer service levels, lack of visibility into future demand, inventory in the wrong place and at the wrong time, and erosion of your margins.
There are a host of enterprise resource planning (ERP) and supply chain management applications available to chemical manufacturersthe challenge is selecting the right one that offers a baseline product with industry-specific functionality. Many ERP applications available today are not industry-specific enough for chemical manufacturers and require major modifications, or, one must select from an industry template that may or may not fit specific needs.
There is also the chance that the software provider may not exist in two to three years (e.g., it may be acquired and the products future may become unknown), or the provider may not be financially secure, adding long-term risk.
Benefits of State Based Control
State Based Control is a plant automation control design based on the principle that all process facilities operate in recognized, definable Process States that represent a
variety of normal and abnormal conditions of the process. State Based Control, implemented with the latest developments in object-based technologies, delivers
direct benefits to its adopters in a variety of Operational Excellence categories. It results in productivity increases, higher asset utilization of both people and process,
automated responses and recovery for abnormal conditions and provides an environment for knowledge capture directly into the control design.

Special Report -- Control With Flow
With changes in temperature, pressure, density and viscosity all affecting volumetric flowmeter measurement, how can continuous processors accurately measure the flow of fluids? Download this Special Report to find out how Coriolis flowmeters provide a direct mass measurement that is unaffected by changing process fluid characteristics improving both accuracy and optimizing operations at your plant.
MES Harmonization in a Multi-Site, Multi-Country and Multi-Cultural Environment
Case Study of a Plant to Enterprise Solution
This white paper describes a case study of a real-life case harmonizing thirteen chemicals plants on one MES platform and bringing the plant floor at enterprise
level the Plant to Enterprise initiative (P2E) . The chemical plants are located on seven different production sites in four European countries: The Netherlands,
Germany, Denmark and Sweden.
Successful Process Communications Best Kept Secret
Sure, the process engineer is proud of his HMI (human machine interface) and the operations manager is pleased with his KPI (key performance indicators) dashboard and how effectively the system is running with the implementation of his new MES/MIS solution. The historian and analytic solution get all the credit when a field equipment crisis is averted. Does anyone ever think to thank the lowly driver? Without data, the HMI is just a pretty picture, and the best analytics in the world are only ideas without any basis in fact. Plus, tens or hundreds of thousand dollars are spent on that, while the driver budget isn't even a line item on the spec sheet. The communication arteries and veins reach out to all areas of the field equipment, sending and receiving data, efficiently and tirelessly ensuring the ability to acquire, analyze and adapt to the situations at hand.
Improving Plant Production with Wireless Condition Monitoring
Mechanical failure of motors, drives and other vital electromechanical equipment are among the most common reasons for production stoppages. Fortunately, recent advancements in vibration monitoring and data analysis have lead to condition monitoring systems that can accurately detect a problem before failure, thus reducing costly machine shutdowns and maximizing production output. These systems are installed on the monitored equipment and are typically networked back to a central computer for data analysis and alarm annunciation. Because the machines may be in remote locations where network infrastructure is not available, or on moving platforms where hardwired network connectivity is not practical, wireless communications is a networking alternative that offer installation cost savings, quicker deployment and even improved reliability in certain situations.

Particle Image Understanding A Primer
This paper will discuss the use of pattern recognition techniques to identify and differentiate different particle types contained in a heterogeneous solution. This application involves imaging the microscopic particles in real-time as they flow in a solution, segregating each individual particle as a separate image, and then applying pattern recognition techniques to differentiate the individual particle types.A framework for discussing the complexity of a pattern recognition operation in this application will be proposed, along with some specific examples showing how this framework applies.

Intelligent Rotary Control Valve
NELES rotary control valves with Q-Trim have greater capacity than comparable globe-style linear valves with noise reduction trims widening rangeability, reducing weight and valve dimensions, and a 50% cost reduction compared to linear valves of comparable Cv. NELES rotary control valves from Metso Automation. Intelligent Reliability leads to Intelligent Results.
Many automation engineers are coming face to face with real fieldbus applications for the first time. Fieldbus offers many benefits, but installation requires some additional considerations over and above normal 4-20mA projects. This whitepaper discusses some of those issues, and shows you how to deal with them.
Why WirelessHART? The Right Standard at the Right Time
The WirelessHART standard provides a robust wireless protocol for the full range of process measurement, control and asset management applications. Based on the proven and familiar HART protocol, it enables users to quickly and easily gain the benefits of wireless technology while maintaining compatibility with existing devices, tools and systems.

Design Considerations for High Liquid Rate Tray Applications
Except for a few odd services, high liquid rate applications are typically the domain of either trays or random packings. Aside from the distributors, random packing designs are rather straightforward with the designer choosing the proper size to accommodate the fluid flow rates and achieve the desired efficiency. Trays, on the other hand, have a large variety of adjustable parameters and can be especially complex, especially when designed for high liquid rate applications.

Applying ISA-S88 to Software Migration Engineering
Dow Chemical maintains thousands of batch control systems world-wide built on its proprietary MOD 5 computer system. Over decades, they have been meticulous to preserve and enhance these systems. Dow intends to preserve and reap the rewards of this diligence by developing reverse engineering best practices and tools to migrate this intellectual property to next-generation platforms.
Managing Complex Equipment Status in a GMP Environment
Batch manufacturing systems must maintain the status of equipment, including which are available, dirty, out of service, etc. In industries that enforce Good Manufacturing Practices (GMPs), additional status types and values for process equipment must be maintained. Rules associated with the equipment status can be complex and involve the equipment class, current equipment state and time in the current
state. This paper covers the operator interface used to review the equipment status and the interlocking requirements between the recipe and batch phases based on multiple status types.
