2009
Borger Gasoline Benzene Reduction
As Systems Team Lead for distillation units Bob -
together with the
client -was
responsible for the HAZOP action items that identified the PSV and CSO decisions,
including validating the design case flaring scenarios. He reviewed the PSV calculations
done in EPCON’s software. In addition, he implemented all Emergency Isolation
Valve and Safety Integrity Level design decisions into the final design.
2009 Ras
Tanura Integrated Project
Part of his work as Project Interface Coordinator - between licensed units and
infrastructure/offsites utilities - involved selection of which stream should go
to which flare, and siting of the flares. This included identifying upset cases
for streams with nitrogen-based compounds to be directed to a special ammonia
flare.
2008 ExxonMobil
Odoptu First Stage Processing
As HSE Lead, Bob was responsible for quantifying the loads to the flare for
well-completion, startup, compressor upset, emergency shutdown and planned
shutdown. With sub-zero temperatures, he sized a larger knockout pot to handle condensables. The design included
specifying lower noise tip to enable
workers to get some sleep during startup. This was complicated by – but
resolved with added soundproofing in bunkrooms– by the impracticality of using steam-assist at -40 C.
2007 ADMA-OpCo Habshan Alpha Platform
As HSE Lead, Bob checked PHAST and
dispersion calculations for H2S-containing vent to flare. Implemented
flow-switch based supplemental natural gas in the event of a sour gas release,
to ensure mix was still combustible at the flare tip.
2007
Marathon Garyville Major Expansion
This was the first major refinery project to be impacted by Jan 2007 upgrade of API 521
from RP to Std – doubling in size plus became an international standard. Bob provided client with a cogent summary of these changes, reviewed unit plot
plans for necessary rearrangement and reviewed the PSV calculation
documentation – now 48 pages thick.
2006 Yorktown
Refinery Low-Sulfur Gasoline
Bob ran FLARENET
scenarios for the worst design case: loss of reflux to a debutanizer column on
a cold winter’s day, Together with bare-pipe radiant heat loss calculations,
proved this release would not condense before reaching the flare knockout pot –
avoiding the complication of a second unit-specific knockout pot.
2005 BP
Cherry Point Canadian eXtra Heavy Oil
As part of debottlenecking study for
processing alternate extra heavy crude, Bob developed scenarios around feasibility
of tieing into the existing high-pressure or low-pressure flare. Determined
conclusively that – even with HIPPS – the site would still need a new
intermediate flare. This also meant the new flare could be tied-in as areas
were shut down one at a time, rather than require a total refinery shutdown.
