In batch processing, there are several things to consider. It’s not unusual for a facility to average more than 1,000 alarms per month. But alarm-remediation projects can reduce total alarms by over 70%. When it comes to blenders, choice can affect end results. As for quality control, what you must understand is you need to focus first on your ingredients, not the product.
To help you improve your batch processing, Chemical Processing has put together an eHandbook. It includes insight on:
- Rethink Batch-Manufacturing Alarm Systems -- You can avoid common failings and improve performance.
- First, Select The Right Blender -- Understand the pros and cons of three key kinds of devices.
- Quell Quality Control Quagmires -- Understand the limits of possible improvements and when enough is enough.
Many companies have old DCS platforms. In computing terms, they’re ancient. Considering all that is connected and controlled by the DCS — thousands of field instruments, valves, operator interfaces and other devices working together to make the process run efficiently and reliably, having an ancient platform is flirting with disaster.
The risks are many:
- System failures
- Part availability issues
- Difficulty integrating new apps and systems
- Reduced support availability
- Operation inefficiency
While the headache of migration is sometimes too much to bear, fortunately, the DCS you install today may never have to be completely replaced because its modularity will allow it to be improved incrementally.
This white paper will detail the steps to make proper migration choices and manage the process to get more out of your DCS system.12/19/2018
The importance of selecting the right process automation technology can far outweigh the cost of an automation investment itself. Selecting the right technology and the right supplier can help your company respond quickly to changing market conditions, ensure long term maintainability, and minimize the Total Cost of Ownership (TCO) over the life of your plant.
The convergence of process automation technologies such as PLC, DCS and SCADA systems have created a situation where it is more challenging than ever for process manufacturers to select the best technology for their application.

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:
- How to better protect your control system - "Defense in depth" is crucial, and new and maturing technologies may help

The debate over the virtues of DCS vs. PLC has been ongoing since these two architectures came into existence 40 years ago. For certain industries, a distributed control system (DCS) provides substantially more value as the basis for automating the plant than a programmable logic controller (PLC)-based system. As functionality differences narrow and price points align, the debate over these virtues is getting more intense and the arguments for and against each system are getting more and more murky. This white paper discusses the “Top Ten” issues to consider when evaluating a DCS vs. building your own “DIY” distributed control system using a PLC-based architecture.07/15/2014
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.09/21/2012

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.02/25/2008
