In the decade before Stuxnet attacked process control systems in Iran, there were just five known supervisory control and data acquisition (SCADA) vulnerabilities for all control systems in the world, according to the U.S. Department of Homeland Security's Industrial Control Systems Cyber Emergency Response Team (ICS-CERT). In 2011, the year after Stuxnet, that vulnerability count jumped to more than 215. Last year, it reached 248. No surprise then that Chemical makers are increasingly focusing on protecting their process control systems from intrusion both from the inside and outside. In this Chemical Processing Special Report: Protect Process Control Systems, we take a look at:

Welded vessels play a key role in most processes. However, few plants now have in-depth expertise in materials selection, fabrication and design of such vessels. As a result, plant staff often make errors that can be costly as well as compromise the suitability and life of the vessel. This three-part special report provides practical pointers that can help you avoid common mistakes and get the most appropriate, durable and cost-effective vessel.
Part 1 looks at a dozen important factors to consider in materials selection, including metal selection and appropriate use of corrosion allowances and coatings. It includes pointers gleaned from first-hand experiences that can help you avoid costly mistakes and delays.
Part 2 provides tips on how to avoid delays and achieve savings in the fabrication process. It also covers techniques that can improve vessel reliability and thus forestall costly repairs down the road.
Part 3 gets into design issues. It condenses the 5,000+ pages of the ASME Boiler and Pressure Vessel Code into a simple guide when specifying vessels, heat exchangers and tanks. It focuses on 10 key factors.

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.
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.
Precise process control strategies have accelerated the use of on-line chemical composition analyzers in plant applications. Contaminants in plant samples are the most frequent cause of problems with on-line analyzers. Trace contaminants can rapidly build up and cause instrument failure.
All of the benefits of Product Lifecycle Management can be erased by significant non-compliance events that impact a company through fines, penalties, negative publicity, or prohibition to sell a new product in key markets. Without a sustainability strategy, the PLM value proposition is at risk.
The pressure of international competition is being felt in the field of plant engineering with a demand for shorter development times and reduced project costs. A consistent and efficient approach to plant design can help to dramatically save both time and money. Download this white paper to learn more.
The use of spray nozzles to rapidly cool or quench gas streams is an essential application in many industrial processes, such as chemical reaction vessels, incineration, and power plant absorber gas inlet. An optimized spray quench design requires engineering analysis of the operating environment, spray nozzle performance and process reliability.
This technical paper describes the design considerations for spray gas quench systems such as nozzle selection, process control, system configuration and reliability. Application of this knowledge can result in a gas quench system that operates efficiently and reliably with reduced vessel size, reduced atomization energy consumption, and minimized downtime, to achieve capital and operational cost savings for your process.
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.
The performance of wireless networks can change over time due to increased performance demands, changes in the radio frequency (RF) environment and changes in the physical environment. This article will explore the use of a wireless diagnostic OLE for Process Control (OPC) server technology to embed diagnostic information in human machine interfaces (HMIs), thus optimizing industrial wireless network performance.

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.
Batch process control security is becoming a critical concern for the process control domain, IT technology infrastructure and the business enterprise. This paper explores several key security concerns in batch control system architectures and methods for addressing these issues.
Industrial automation is no longer limited by the walls of a production facility. More and more automation is being handled via remote communication, whether its from the office or from the comfort of your own home. Todays PLCs give you the ability to access your control system to
handle such tasks as monitoring via a website to determine the condition of a machine or check other statistics.
This document describes best practices for the reference architecture for a process control system network and its interfaces to a corporate network. The papers objective is to give the reader an understanding of the techniques utilized to securely connect these networks.
This application note from Delta Controls outlines selection and installation criteria for using admittance probes to monitor the level of powders, liquids and other materials. Dielectric constants of more than 200 materials are included.
