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.
Efficient transfer of weighing process data to higher level PLC, MES or ERP systems makes manufacturing processes more efficient and more transparent. But identifying and implementing the most effective system for data transfer and integration can be challenging.
Ensuring the security of industrial control systems is hardly a new topic. The earliest users of modern control systems in power stations and chemical plants saw the need to protect access to vital control functions from unauthorized use. Similarly, in industries such as fine chemical or pharmaceutical
where the process is the product, manufacturers have always sought to protect the secrets of their unique processes from the prying eyes of industrial spies. This white paper by ARC describes how the Siemens AG PCS7 Security Concept bundles key security measures in seveal specific areas to create a deep hierarchy of security known as defense in depth.
Medium voltage VFDs are high cost, high consideration assets that greatly improve process control and efficiency in manufacturing facilities. It is vital that you and your company understand the TCO of this asset. Download the white paper for more information.
Level measurement, which is the detection of the phase split between vapor/liquid, liquid/liquid, vapor/solid and even liquid/solid, is a key parameter in the operation and control of modern industrial processes. A reliable outcome depends on the phase conditions being relatively consistent under all process conditions. Unfortunately, the importance of level control isn’t always understood. Failure to measure level reliably has resulted in some of the most serious industrial accidents, including those at the Buncefield, U.K., fuel storage depot and BP’s Texas City refinery. In this Chemical Processing Level Management eHandbook, we discuss best practices for level management including:
How to Select the Right Liquid Level Sensor - It’s important to consider a variety of factors when choosing the type of technology
Multivariable devices - gain operating and maintenance benefits
Achieving level control with dP transmitters - it appears simple but really is not

Synthesized is used in a variety of applications. The construction industry uses it as the primary ingredient in drywall, and as a setting inhibitor in Portland cement. The property of Gypsum that makes it valuable as a fire retardant in construction materials is also what makes it a good candidate for Loss on Drying analysis.
The key components needed to provide valuable information about the composition of a producer's FGD byproducts is an instrument that has capabilities to reach temperatures sufficient to drive the reactions of interest and to separate the tests so meaningful numbers are yielded at each stage.
This white paper outlines how the chemicals industry's leading operators are successfully transforming their operations to achieve a competitive advantage for decades to come. Learn what chemicals operators are doing to: improve integration and collaboration with supply-chain partners both upstream and downstream; Establish business processes and use management systems to better identify and manage both customer demand and volatile supply channels; Innovate both new products and feedstock sources and, Upgrade operations and optimize processes with improvement methodologies such as Lean.
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.
Implementation of rapid loss on drying and ash analyzers significantly reduces testing times associated with traditional methods, allowing companies to bring products to market faster, increasing production. These features will aide biomass material manufacturers in maximizing control of the market.
Gaseous oxygen measurement with amperometric sensors is the most direct and easiest solution for oxidation and explosion protection.
Unwelcome oxygen Tank blanketing is the process of filling the headspace in storage vessels and reactors with an inert gas to prevent its contents from exploding, degrading or polymerizing and to protect equipment from corrosion. A blanketing system is normally designed such that it operates under higher than atmospheric pressures, therefore preventing outside air from entering the vessel. As oxygen and moisture in the air can be undesired in numerous processes and applications, blanketing is done in a wide range of industries, varying from (petro)chemical to food and beverage, pharmaceutical to pure water.
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.
Patching process control system software to remove security vulnerabilities is fraught with risk. System issues can be the result of installing a patch, but a system is also vulnerable without patching. Fortunately, virtual patching can improve the process and raise the system’s security at the same time.
While upgrading process control systems is vital to maintaining a plant’s performance, the migration process often brings confusion and frustration for customers. See how Honeywell keeps control systems running at the best possible performance throughout the migration process and into the future.
Dependable pH determination in chlor-alkali brine is notoriously difficult. Process conditions and high impedance signals from pH sensors mean maintaining measurement accuracy has been a headache for instrumentation engineers - until now.
The Every Man’s Guide to OPC is an easy-to-read overview of the most popular industrial open connectivity standard - OPC. This paper introduces the main idea behind OPC, shows why OPC is different from conventional (often proprietary) communication protocols, and explains how OPC helps overcome the limitations of such native protocols. Next, the paper explains what the building blocks of OPC are (OPC Clients and OPC Servers) and how they work together to make data-sharing possible.
This guide to OPC helps readers of all technical levels quickly grasp what OPC is and how they can use it.
Harmonics can have a detrimental effect on power generators and other sensitive electrical equipment for the user and utility alike. The number of adjustable speed drives (ASDs) has increased significantly in the past decade. Their contribution to the total electrical load of a power system is significant and cannot be neglected. This white paper discusses various passive techniques for reducing input current harmonics.
With an aging installed legacy Distributed Control System (DCS), the PRALCA petrochemical plant needed advanced control strategies to improve plant efficiency. Find out how a comprehensive migration solution extended the life of plant equipment and provided a cost-effective path forward to the latest automation technology.
Oxygen measurement for safety and control is essential for process optimization in many chemical manufacturing processes. This white paper provides application details of probe-style TDL oxygen analyzers.
