discover."

"CVE cut our
process losses by 40% and de-bottlenecked part of our process - all
for zero capital cost." Senior Process

2%
increase in Efficiency, false alarms reduced from
49% to less than 10% at the first attempt, Start-up
time reduced by a factor of 6. IneosChlor, UK
"I found
CVE a really good way to quickly find answers to
the plant managers questions. It was especially good
because we have many process variables with tight
constraints to be met." - Senior Engineer, pX
Limited, UK
Geometric Process Control (GPC)
is focused on reduction of variable operating costs
in the process industries and shortening the product
development time in pharmaceuticals and speciality
chemicals by providing Faster Formulations. It is actually a very general
multi-variable technology
with wide application wherever data exists so call us if you are in
another sector but think GPC might help you.
GPC is in use at over
120 large process sites worldwide in Oil Refining,
Petrochemicals, Oil & Gas Exploration and
Production, Pulp and Paper, Minerals Processing, Elastomers and Polymers, Oil Well Drilling, Metals,
Commodity Chemicals, Pharmaceuticals, Glass,
Speciality Chemicals, Power Generation, Cement and
process applications in Defence and Aerospace.
If you would like to know how
you could benefit from Curvaceous Software
Solutions, please
Contact us
for more information or to discover how
GPC can be used for:
-
Operating Envelope Models
for Batch or Continuous Process Control - multi-variable
models including all variable interactions of the space where your process performs
best. Stay in this space and keep your process
working at its best all the time and not just
some of the time. Easily created without maths
and provide early detection of abnormal events
too. Includes optimisation for secondary
objectives such as least energy usage or minimum
cost operation.
-
Find your best
Operating Box. You
probably operate today using fixed operating
limits defined on individual variables.
Geometrically this is actually a box because you
have ignored interaction between the variables.
This is where you or we start using CVE's
patented Box Query to quickly find a set of
fixed limits that give the best yield of your
objective and simultaneously tell which process
variables should be improved first.
-
Alarm Management.
All the problems of alarm systems begin and end
with the values at which the alarm limits are
set. But there is nothing in the chemical
engineering literature about how to calculate
alarm limits. GPC is the first and only
method with a scientific basis for calculating
both Alarm Limits and Alerts. We do it for many
variables at once so it is much faster and the
alarm limits are better because they are
Consistent with each other. Users have found it
cuts the time spent in Alarm Rationalisation projects
by at least 20% as well as giving better alarms
and a safer and more efficient process. It makes
the subsequent Management of Change easier too
and you wont have to repeat the Alarm
Rationalisation project every 5-7 years either.

Process
Analytical Technologies
(PAT) THE only complete
solution taking you all the way to intrinsically
safe predictive control of multi-phase,
multi-stage batch processes.
-
Spectral Analyser Support
- wouldn't you like to see all of an NIR or
Rahmann spectra, visually compare it with
spectra for reference substances and then join
the spectral data to process operating data so
that you can see and discover the operational
causes of new or changed peaks in the spectra?
And all without needing any maths...
-
Problem
solving and process stewardship
- addressing the needs of front-line process
operations engineers for a quick and easy-to-use
method to answer the everyday questions in a
plant such as 'why isn't the process working as
well as it did last week?' as well as checking
that improvements already made remain made.
-
Quality by Design
(QbD)
be able to
demonstrate by showing visually how your process
knowledge is built into your product design
-
Multi-Phase
Batch Process Control.
Batch processes were always
difficult to analyse and control because there
were so many variables changing at once and so
many quite different sets of activities taking
place in sequence. Users were not able to
directly compare the many tens or hundreds of
process variables and quality results across
batches in a meaningful way let alone the
reasons for the differences in performance of
two or more supposedly identical reactors.
Process control has been limited to forcing the
trajectory of a single variable, such as reactor
temperature, to follow the same trajectory as
that in a ‘golden’ batch. That was the past. Now
they can compare many batches and many reactors
with ease and go on to build real-time control
models without maths.

Process Data
Mining without maths for the Support
Specialists. Explore datasets containing
hundreds of process and quality variables and
tens or even hundreds of thousands of rows
entirely visually using CVE's sophisticated but
simple to use Query capabilities to drill deeper
than you have ever drilled before. Discover
black holes, different operating Modes,
unsuspected relationships yet be able to
communicate your findings easily to anyone on
your site.
-
Faster Formulations -
A new way to
Formulate by giving the
experimenter the
ability to visualise and visually explore the Response
Surface created from a set of
Designed Experiments so
that he can apply his domain knowledge to the
full, save a lot of time and sometimes eliminate
an experiment. GPC methods eliminate todays
fitting of the surface with regression equations
and the mathematically-skilled and
time-consuming process of interpreting them.
