How NOA can add value for process analytics

When it comes to NOA, there is much talk about leaving the classic automation pyramid and the resulting consequences, especially with regard to (data) security. There is no question that this must be ensured. Many initiatives are on their way. This blog article aims to show why these efforts are worthwhile. The PAT demonstrator, which was presented at the NAMUR Annual General Meeting in 2018, serves as an example here.

Safety needs friends… (Part 2/2)

As we have seen in part 1 of this article, there are processes that cause a system’s performance to (prematurely) deteriorate or that the system can no longer fulfil its purpose. As we will see, these processes are not so different for cars (part 1) and safety systems in the process industry. However, there is a big difference in the rules and regulations during operation. We drivers have a bit of the “main inspection” and perhaps the “inspection booklet” of the manufacturer on our backs. Otherwise the legislator more or less leaves it to us to admonish to be on the road with a “safe” vehicle. This is quite different with regard to safety in the process industry. There is a multitude of laws, rules etc. that must be observed.

Safety needs friends… (Part 1)

Security needs friends, because it has enemies! Also in the process industry. The example “Car” in part 1 of our new #Series tells you which enemies safety has!

Assistance systems 3 – The “signpost” & the “predictor”

Can you do that? Is there? Surely both production managers and plant operators have already asked themselves these questions. To become more concrete: You, as a production manager, have experienced plant operators and you know that you have taken good care of your control and alarm strategy. Functional safety is also up to date. You won’t burn anything. Nevertheless, something is bothering you: No matter how stable and safe your system is, you don’t really know how efficiently it drives. Isn’t there the famous “grain” left in it?
Or let’s put ourselves in your place as a plant operator: you have been operating your plant for years and know it well. From time to time she does her “talking tricks” and you don’t know why. Although you keep to the allowed temperature step in the reactor, it is about to go through or it is going through. Such an “early warning system” would be very practical. This runs in real time and warns you in advance that something is going to go wrong. Then you still have enough time to react accordingly. Something like a “process crystal ball” would be good. But is there such a thing?

Assistance systems – 2. Electronic stability control

It’s desperate. The level in the column sump is simply unstable and fluctuates like a drunken sailor. The process control system (PCS) and the plant operator are constantly occupied with keeping these fluctuations under control to such an extent that the plant is at least running and no permanent alarm is triggered. And what have we not already tried everything. Tuning the control loops in the PLS, improving the instrumentation, looking for process or control connections that cause these problems and so on.

Pharmaceutical Single-use Technologies: An Environmental Trade-off?

The motivation to reduce costs, meet regulatory requirements and improve process flexibility has led many pharmaceutical companies to consider single-use, pre-sterilised plastic equipment systems as an alternative to stainless steel. Single-use equipment makes the pharmaceutical manufacturing process increasingly efficient and less costly. However, with the environmental impact of increased plastic waste making headlines, and limited recycling opportunities facing the industry, is there an environmental trade-off happening?

Third column of Dr. Andreas Helget

BLOG / In his third column, Dr. Andreas Helget, Managing Director of Yokogawa Germany, deals with the topic of sustainability in the chemistry sector. It is an open secret that in view of the immense consumption of raw materials in this industry, the “key” to the future of sustainable chemistry is being feverishly sought. What role biomass, i.e. (micro)algae, play in this context can be read here.

Assistance systems – 1. Our little daily helpers

Even in the age of smartphones and the like, our car is one of our favourite technical toys. Whether for reasons of safety or comfort, more and more assistance systems have found their way into the process of driving a car – as in the process industry. The mini-series starting with this article deals with what assistance systems there are, what typical applications are and what benefits they bring.

System integration – when less is more

Yokogawa has been making ASI – Analyzer System Integration – successful for more than 50 years. But in addition to these so-called greenfield solutions, Yokogawa also offers customized, smaller solutions for brownfield systems if required. So it’s a kind of ASI light.

Hand in hand with the process data

Alarm! Is there now a hectic rush at the control station? Or does the operator lean back and relax, press a button to acknowledge the alarm and continue to sip the coffee he bought a minute ago?
Both are possible, both are interesting information – usually when it comes to alarm management for the analysis and reduction of alarms according to EEMUA 191, for example. But even at the beginning of a data analysis, a look at this data makes sense.
