Insights:
O&M
spending for plant performance
improvements continue as capital
spending is curtailed
While capital
budgets are constrained, plant
O&M budgets continue to
finance daily operations with
emphasis on energy efficiency and
production optimization. As
product demand and rig counts
fall, the resulting turn-down at
many gas processing plants calls
for control loop re-tuning and
operator re-training to handle
reduced rates while maintaining
product quality and minimizing
product giveaway. BDP Inc.
provides consulting services to
audit existing control
strategies, to evaluate current
plant performance, to tune
complex loops, to re-train
operators on loop interactions
and process constraints, and to
recommend control strategy
enhancements that improve product
recoveries and reduce energy
consumption. Cost effective
designs automatically control
within known constraints and
provide rapid response to process
upsets, which reduces callouts
and reduces wear and tear on
process equipment caused by
frequent trips and
restarts.
Recent BDP Inc.
projects have identified target
benefits such as the processing
opportunities listed below.
<> Cryogenic
gas plant strategies that
increase recoveries, coordinate
parallel train processing, and
maintain tighter product
specifications based on real-time
process demand.
<>
Refrigeration load management
strategies that respond to
disturbances in the plant inlet
rate and disturbances in the
refrigeration system, acting
rapidly to prevent carryover
while always returning the
chiller to efficient operation
once the disturbance has been
rejected.
<> Hot Oil
systems incorporating multiple
Waste Heat Recovery Units in
parallel with large fired
heaters have been optimized to
automatically drive the Hot Oil
system toward maximum utilization
of waste heat capacity and
reduced fuel consumption by the
fired heaters.
<> APC
solutions for NGL Fractionation
facilities that reduce the
variation in product quality and
provide optimization strategies
that drive product targets toward
more profitable operations.
In today’s
competitive market, implementing
reliable Advanced Regulatory
Control (ARC) strategies directly
on the installed control system
can deliver sustained benefits
while minimizing long-term costs
for strategy maintenance and
usually without additional
control hardware and software
purchases. BDP advanced
control designs and
model-predictive composition
controls have performed extremely
well to improve product yields
and to reduce operator workload
while delivering tighter
performance specs with automatic
response to load changes and
process upsets.
BDP Inc. offers
process control consulting,
advanced control strategy design
and implementation, and system
integration services to deliver
overall control system
performance enhancements.
