Insights:
BDP
delivers Advanced Regulatory
Controls that benefit daily
operations
BDP Inc. enhanced
regulatory control strategies
have been implemented at various
gas processing plants to deliver
improved product performance and
increased plant stability.
These advanced strategies are
typically configured directly in
the DCS or PLC control system,
using the native programming
features available in the vendor
software. Implementing
advanced control strategies
directly in the DCS/PLC
controller delivers robust and
reliable control strategies for a
minimal investment in process
control engineering skills.
Sample advanced regulatory
control strategies implemented by
the BDP team are further
described below.
Chiller
Level Management
<> In many
plants, inefficient chiller load
control results in varying
refrigerant level with vapor
superheating or refrigerant
carryover that has a negative
impact on compressor
performance. BDP Inc.
offers a Chiller Load Management
strategy that responds 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.
Industrial
Boiler Control
<>
Traditional power plant
applications for management of
direct-fired boilers, including
steam drum level control, can be
applied to industrial boilers
used in gas processing
plants. These BDP
engineered strategies determine
the steam demand based on the
steam consumers to manipulate the
DCS based Master Steam Header
Pressure Controller. The
individual boiler firing rate,
air-to-fuel ratio, excess O2
control, and three-element
feedwater control strategies
provide individual boiler
management and coordinated
control across multiple boilers.
Thermal
Oxidizer Control
<> BDP
engineered strategies have been
successfully implemented to
simultaneously regulate
incinerator temperatures for
emission control and regulate
waste heat recovery duty for
process control. These
automatic strategies
significantly reduce the level of
operator attention, provide rapid
response to process upsets, and
permit consistent attainment of
emission reduction goals, while
delivering a coordinated strategy
for heat medium temperature
control.
BDP Inc. offers
process control consulting,
advanced control strategy design
and implementation, and system
integration services to deliver
overall control system
performance enhancements.
