| BUSINESS UNITS:
OPTIMIZATION |
This is another core service
where we stand above our competition.
We believe that unit based optimization is more powerful, more
robust, easier to understand and implement and less costly than
plant wide optimization.
We have developed several proprietary methods of optimizing each
facility unit taking into account all the parameters that can affect
the profit margin. We will incorporate these optimization solutions
into the advanced controls schemes.
We provide several on-line calculations that demonstrate the
performance of the unit. Once trended, these values can be used to
pinpoint areas where the plant performed above or below expectation
and analysis could be made to find out the root cause. This tool has
been very successful in the past and has been very beneficial to our
clients.
We provide both open-loop and closed-loop solutions. An example of
where we have implemented a closed loop solution is where we have
calculations that will reduce the profitability of a particular
product once there is reduced demand or once the tank(s) is/are
full. A closed-loop solution will then optimize production of the
other products at the expense of the undesired product.
Here is an example where we implemented an open-loop solution in an
Air separation plant where we had just installed Model Predictive
Contols (MPC). Upon analyzing the data, we discovered that two weeks
after implementing MPC, our profit margin had taken a dive from
about $260/hr profit to about $63/hr. We made an inquiry and found
out that the Liquifier warm turbine was leaking and some Main Air
Compressor (MAC) coolers/chillers were not functioning properly. A
quick calculation showed that at the average Air flowrate, the plant
was loosing about $5,000 per day. The problem was escalated and
resolved in 2 day. The problem had existed for a little over two
weeks prior. Had the plant personnel made it a priority to utilize
our tool earlier, they would have saved about
$75,000 because they eventually had to repair the
problem and customer demand was high. Many of these problems exist
today and need immediate attention. This is where we thrive and
enjoy bringing solutions to such complex issues.
Our solutions help point out the most optimal conditions to run the
process at every instance by calculating the instantaneous profit
margins.
We will not only implement these solutions but will like to work
with you in analyzing the data be it daily, weekly or monthly. It is
easy to transfer data these days. Artcon has the will capability of
analyzing your plant data and recommending solutions without setting
foot at the site. Artcon Engineers will come to the plant only to
install the solution saving you time and money. |
