All the terms below mean exactly the same thing
• SCADA = Supervisory Control And Data Acquisition
• HMI = Human-Machine Interface
• Process Visualization software
• DCS console software
SCADA/HMI/Visualization/DCS console is a class of software that
presents data available at DCS (Distributed Control System) or
PLC (Programmable Logic Controller) in a form that a human can
understand. The plant personnel can also manipulate the settings of
DCS/PLC directly from such SCADA systems, as a modern
alternative to a traditional control room.
SCADA systems come from independent software houses or from
DCS vendors. The most popular independent SCADA systems are
Intellution’s FIX, OSI’s PI, and Wonderware’s Intouch. All stateof-art SCADA systems are compatible with Microsoft Excel.

from Nor-Par Online A/S
• SCADA2CC runs online process simulation driven by true
production data in CHEMCAD
• SCADA2CCD runs real-time process simulation driven by
true production data in
CC-ReACS and/or CC-DCOLUMN
• SCADA2CCP runs real-time process simulation driven by
true production data in
CC-POLYMER and/or CC-DCOLUMN

SAVINGS
The savings that can be achieved by using the integration
of SCADA with Chemstations software will be result of:
 Running the plant with high quality product, less
pollution, and faster using the existing equipment
 Online optimization of the production
 Maintaining better product and production
documentation, according to FDA and other
procedures/standards
 Reducing the duration and cost of start-up
 Limiting shutdowns only to planned ones
 Avoiding breakdowns and unpleasant failures
 Optimizing, calibration and tuning the control system in
short period of time
 Training operators to higher level of understanding
23
SAVINGS EXAMPLE
We are talking about substantial savings.
We have a client that makes and operates many 5 kt/y
units for on-site production of Chlorine Dioxide. This is
one the smallest production capacities at which
continuous processes are operated.
This technology was mastered by the client who had been
using CHEMCAD and a SCADA system for several
years.
Yet, applying the SCADA2CC has brought the client
additional savings estimated to $70,000 yearly per each of
aforementioned small units.
24
ECONOMIC JUSTIFICATION
We have understood from works we have done under
secrecy agreements with some of our clients that:

For a well operated advanced plant producing commodity
chemicals and already using SCADA systems for several
years, the savings could be estimated to 1 – 1½ % of
operating cost

For a commodity chemical manufacturer who has just started
using SCADA systems, the savings could be at least 1½ 3% of the operating cost

For a large plant such as Oil Refinery already using SCADA
systems for several years, the savings could be estimated to
0.2 – 0.5% of the operating cost

For a large plant such as Oil Refinery that has just started
with SCADA systems, the annual savings could be at least
0.5 – 0.8% of the operating cost
25
WHAT ARE THE OTHER SAVINGS?



If you could deliver the product with better specifications,
and every production unit could be better controlled…
What are the savings? Ask yourself
If you could quickly change to make another product with
existing equipment, especially if you need to follow the
FDA rules and get the FDA acceptance…
What are the savings? Ask yourself
If you could get a large contract based on better
production planning, better documentation, and better
product quality
What are the savings? Ask yourself
For some it could be 50% savings, and for some 5%.
We believe 10% of savings first year will return many
times the investment in CHEMCAD and the SCADA
integration
