ONLINE PROCESS SIMULATION
SCADA/HMI/DCS VISUALIZATION INTEGRATION WITH
CHEMSTATIONS SOFTWARE
SCADA2CC INTERFACE
2
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 Intellutions FIX,
OSIs PI, and Wonderwares Intouch. All
state-of-art SCADA systems are compatible with
Microsoft Excel.

STEADY STATE OR DYNAMICS
  • Steady State SCADA integration
  • Based on Online Process Simulation principle,
    modeling the plant behavior by continuous series
    of steady state approximations
  • Requires least effort to construct and calibrate
    the flowsheet
  • Ideal for economic analysis and online
    optimization
  • Requires CHEMCAD only
  • Can only be applied to process units between
    intermediate and storage tanks
  • Dynamic SCADA integration
  • Based on Real Time or Accelerated Dynamic
    Process Simulation principle
  • Takes into account true dynamic behavior of the
    plant, including equipment size, accumulation,
    and control system unit operations
  • Ideal for troubleshooting, control loop tuning
    and real time optimization
  • Requires CHEMCAD and CC-ReACS or CC-DCOLUMN or
    CC-POLYMER

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

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.
25
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

26
WHAT ARE THE OTHER SAVINGS?
  • If you could deliver the product with better
    specifications, and every production unit could
    be better controlledWhat 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 qualityWhat 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
