Chemical Processing Special Report: Secure plan(t)
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 (Figure 1). 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: Secure plan(t), we take a look at:

OPC: The Ins and Outs to What it’s About, The Every Man's Guide to OPC
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.
Whitepaper: On-Line Instrumentation Helps Lower DAF System Costs
Many industrial plants use dissolved air flotation to remove fats, oils and grease, and suspended solids from wastewater. Chemical additions are often kept higher than necessary to account for variations in influent water quality that are characteristic of industrial facilities. Continuous monitor
Integrating Process Weighing Data
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.

Chemical Processing Flow eHandbook: Monitoring Flow
The purpose of installing a flowmeter system is to accurately measure flow in a reliable manner. Issues related to physical properties, process parameters, electronic features and interconnections are often given much consideration. Relatively little emphasis, however, is given as to how well the flowmeter will perform its intended purpose. Adding to the confusion are the differences in how performance is expressed and the incomplete nature of the available information. Nevertheless, the quality of flow measurement should be a concern. This Chemical Processing eHandbook takes a look at technologies and solutions affecting flow including:
* Coriolis meters - steps you can take optimize performance when faced with entrained gas
* Magmeters -- why you should consider using them
* How to achieve effective flow control with centrifugal pumps
White Paper: Helping Business Users Understand and Measure Data Quality
Many companies have invested heavily in mission-critical business software initiatives. Much time and effort has gone into deploying sophisticated customer relationship management solutions, adaptive supply chain software, ambitious data migration projects, and other endeavors. All too often, however, these worthy but expensive initiatives fail to deliver anticipated benefits because theyre hobbled by poor data. Download this white paper to learn how to understand and measure your business data for successful application.
Maximizing Power from Biomass
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.
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.
