- Name of the facility:
Northwestern Whatcom County, 7 miles southeast of Blaine, Washington.
- Distance from the US/Canada border:
- Type/size of the facility:
Large complex petroleum refinery (225,000 barrels crude processed per day) is proposing a Clean
Gasoline Project. The project consists of a Straight Run Naphtha Dehexanizer, a Naphtha Hydrotreater,
and a Benzene Saturation - Isomerization Unit (UOP Penex-PlusT). The purpose of the project is to
process light naphtha feedstocks to produce a gasoline blend component that has essentially no
benzene, olefins, or sulfur, and is higher in octane than its feed. The project will allow the
refinery to meet the 2005 federal standard for sulfur in gasoline and will decrease benzene in all
gasoline produced at the refinery.
- Source of emissions:
New Isomerization Unit (process heaters and fugitive emissions from equipment leaks), Existing
Boilers, Existing Hydrogen Heaters, Existing Storage Tanks, Existing Sulfur Recovery Unit.
- Type of fuel:
- Type/quantity of emissions &
Emission control technology:
BP is required to install best available control technology (BACT) on new Isomerization Unit process
heaters. For the two new process heaters (100 MMBtu/hr & 18 MMBtu/hr), BP estimates the following
potential emissions and proposes the following controls as BACT:
|Pollutant ||Quantity of Emissions |
(tons / yr)
|Emission Control Technology|
|NOx ||18.1 ||Callidus Ultra BLUE Low NOx burners (or equivalent)|
|PM10 ||3.9 ||Proper combustion|
|SO2 ||28.9 ||NSPS Subpart J compliant refinery fuel gas|
|VOC ||2.8 ||Proper combustion|
|CO ||23.7 ||Proper combustion|
- VOC emissions from new Isomerization Unit equipment leaks will be controlled through compliance
with EPA's Refinery MACT requirements at 40 CFR Part 63, Subpart CC. This MACT is considered
BACT for this project.
- BACT is not required of units simply experiencing an increase in utilization. These units
include existing boilers and hydrogen heaters.
- BP anticipates increased feed to the Sulfur Recovery Unit by less than 1 percent, and no
detectable increase in emissions is anticipated.
- BP estimates that evaporative VOC emissions from existing tanks will decrease by 2 tons
annually as a result of this project.
The overall project's emissions increases (not considering contemporaneous emissions increases and decreases)
are as follows:
|Pollutant ||Quantity of Emissions|
(tons / yr)
