 Venezuela's
PDVSA calls on DeltaV for robust, flexible control
The complex production process for PDVSA's 56-well oil field
is extraordinarily dynamic and constantly expanding. PDVSA
called on Emerson Process Management's DeltaV digital automation system
for the robust automation, high-level flexibility and scalability
it needed. While quality was a factor, administration and
maintenance had to be held to a minimum in order to reduce
costs.
Continued success
The DeltaV system, with Emerson's PlantWeb architecture
and FOUNDATION™ fieldbus technology provides control for liquid
gas separation, an air-blown gas cooler, and mist eliminator
vessel. Four fieldbus segments connect a DeltaV digital automation
system with Rosemount intelligent level, pressure, and temperature transmitters.
What initially had been planned as a small trial installation
was so successful that PDVSA began expanding it almost immediately.
Bottom Line Benefits
Among the many benefits PDVSA gained from the DeltaV system and FOUNDATION
Fieldbus were:
- Scalability to match a constantly expanding process
- shorter installation (15 days compared to five or six
months or even longer for traditional solutions)
- faster configuration (almost 20 instruments in only 3
days)
- Better process stability, resulting in less waste and
improved regulatory compliance
 Says
PDVSA's project engineer Manuel Rangel, "Having an integrated
operating environment with robust control like the one offered
by fieldbus, integrated with PlantWeb, allows you to obtain
a stable operation, minimizing deviations in the processes,
and therefore minimizing the venting of contaminants into the
environment."
