Abstract
Living the Process Safety from
Instrumentation and Control Projects, a successful case
safety management system, and the importance of implementing it in the
organization, but the question is: how come true and strengthen the process culture,
getting a real risk reduction in the facility?. The area of Instrumentation
and control plays a key role in achieving this objective and Equion reflects
this.
a company to develop projects and identify opportunities to improve efficiency
or production, but are we evaluating their impact on Process Safety? Equion was
no stranger to this situation, and as a need and opportunity to reduce
operational issues and optimize production, started three (3) years ago an
action plan for updating the control systems of plants, prioritizing aspects of
Safety process, aiming to increase reliability, simplicity of operation and
maintenance, and understanding that the operator is a critical protection layer
but with a very low reliability who requires maximum support by technology aiming
to reduce errors.
systems fulfill the objective of allowing the operator to quickly identify the status
of the plant and prevent an incident escalation?
to have a stable process, but we are aware what involves reducing process
variability accompanied by a loops management control system to allow
continuous monitoring of the tuning of facility?
adequately and timely respond to flood of alarms greater than to 1000 alarms per
hour? An alarm management system to make a right identification, prioritize
based on severity and response time, using a tool based on software to manage
on real-time is the key.
the Maintenance of control and instrumentation systems is reduced to have a
preventive or corrective maintenance, but from the perspective of process
safety is not enough, and an Asset Management System is the solution.
results obtained because of these developments are:
we havenxt had unplanned shutdowns of plant due to process upsets, while three
(3) unplanned shutdown occurred in 2010 and during stabilization process of
one of our facilities , four (4) unplanned shutdowns.
control hardware diagnostics originated 4 events in 2 years, with the asset
management system installed, we havenxt had such problems.
(500) average Alarms per hour in the last year, currently eighty three (83)
alarms per hour , it is a high rate, but we sure that we are on the right way.
implemented or in going and their impact in Process Safety.
