## 5.2.1.3 CO & VOC BACT A NALYSES FOR 

## I NTERNAL 

## C OMBUSTION 

## E NGINES



## CO & VOC are formed due to incomplete combustion of the diesel fuel in the

combustion chamber and depend in varying degrees on the extent of fuel

mixing, resulting air-to-fuel ratios, comb ustion temperature, and residence time.

Emissions of CO are an intermediate product produced by the incomplete

combustion of hydrocarbons. The emissions are formed in hot, oxygendepleted regions of the combustion chamber and at the edges of the lean flame

zone where the temperature is lower. Short residence times also contribute to

CO formation. Most of the VOC in diesel exhaust are the result of unburned

fuel, although some are formed as combustion products. Engine operating

conditions such as engine load and injec tion timing play a role in the formation

of VOC emissions from the diesel engine.

The maximum hourly electricity needed from 8 power plant engines for station keeping and drilling is 15,000 kW. Therefore, a total of 4 engines operating simultaneously at 96.8% load (16,200 kW) is assumed to represent maximum hourlyemissions. While it is possible that more than 4 engines may operate simultaneously, the total maximum hourly electricity generated will not exceed 16,200 kW. Wireline and cementing operations will not occur at the same time, therefore worst-case of the two operations is used in the worst-case hourly operating profile. Only 10% of the maximum hourly emissions of the emergency generator areincluded because in the worst-case hourly operating profile the emergency generators will be tested without applying a load (idling).TOTAL- Support VesselsTOTAL - C.R.

[1] Represents maximum power output of the generator in kilowatt electric.

[2] Represents annual average load for 8 main power plant engines calculated based on an annual average station-wide electricity need of 15,000 kW for station

keeping and drilling. Annual average load % = 15,000 kW /(4,184 kW x 8 Units).

[3] BHPB is proposing the use of Ultra Low Sulfur Diesel for all diesel combustion sources.

[4] Emission factors are based on AP-42 Chapter 3, Table 3.4-1, Emission Factors for Large Stationary Diesel and all Stationary Dual-fuel Engines (October 1996).

[5] PM 10 and PM 2.5 emission factors based on AP-42 Chapter 3, Table 3.4-2, Particulate and Particle-sizing Emission Factors for Large Uncontrolled Stationary Diesel

Engines (October 1996). An average brake-specific fuel consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr. PM < 3um taken as

PM 2.5 . Total particulate emissions is the sum of filterable and condensable particulate emissions.

[6] Represents proposed BACT limits developed based on "top-down" BACT analysis and using data from stack testing conducted from March 31, 2010 through April

3, 2010 by COMM Engineering. Three test runs were conducted at approximately 40% and 60% loads each.

[7] BHPB is proposing the use of Ultra Low Sulfur Diesel for all diesel combustion sources. Therefore, emissions have been calculated based on a maximum sulfur

content of 15 ppm in diesel fuel assuming that 98 percent of sulfur in the fuel is oxidized to SO 2 and 2 percent of sulfur in the fuel is oxidized to H 2 SO 4 based on Draft

[11] Emission factors based on AP-42, Chapter 3, Table 3.4-4, PAH Emission Factors for Large Uncontrolled Stationary Diesel Engines (October 1996).

[12] For all pollutants except NOx and CO, the maximum hourly emissions (lbs/hr) are calculated based on the appropriate AP-42 and EPA emission factor and the tot a

engine rating of 5875 HP (mechanical), as the AP-42 and EPA emission factors are based on brake HP. For NOx and CO, the maximum hourly emissions (lbs/hr) are

calculated based on the stack test emission factors and the maximum generator electric output of 4184 KW as the stack test factors are based on the actual KW

generated.

[13] Annual emissions are calculated similar to maximum hourly emissions except that annual average load% is applied, and emissions are based on annual operating

hours.

[14] An average BSFC of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr to calculate emissions.

[15] The emission factor for CO 2 is based on AP-42 Section 3.4. Large Stationary Diesel and All Stationary Dual-fuel Engines, October 1996. The emission factors for

CH 4 andN 2 O are based on Inventory of U.S. Greenhouse Gases and Sinks: 1990-2008 (April 2010), U.S. EPA # 430-R-10-006, Annex 3, Table A -81. Emission factor

The maximum hourly electricity needed from 8 power plant engines for station keeping and drilling is 17,500 kW. Therefore, a total of 5 engines operating simultaneously at 100% load (18,000 kW) is assumed to represent maximum hourly emissions.While it is possible that more than 5 engines may operate simultaneously, the total maximum hourly electricity generated will not exceed 18,000 kW. Wireline and cementing operations will not occur at the same time, therefore worst-case of the two operations is used in the worst-case hourly operating profile. Only 10% of the maximum hourly emissions of the emergency generator are included becausein the worst-case hourly operating profile the emergency generators will be tested without applying a load (idling).Allie (Work Boat) Storage Tanks - TOTALFast Skipper (Crew Boat) Storage Tanks - TOTALBHPB Sake - DD1 Emission Calculations_v2.0 - Hourly Emissions Summary10/14/2011Page 6 of 6

An average brake-specific fuel consumption (BSFC) of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr.

[10] Emission factors based on AP-42, Chapter 3, Table 3.4-3, Speciated Organic Compound Emission Factors for Large Uncontrolled Stationary Diesel Engines

(October 1996).

[11] Emission factors based on AP-42, Chapter 3, Table 3.4-4, PAH Emission Factors for Large Uncontrolled Stationary Diesel Engines (October 1996).

[12] For all pollutants except NOx and CO, the maximum hourly emissions (lbs/hr) are calculated based on the appropriate AP-42 and EPA emission factor and the total

engine rating of 5096 HP (mechanical), as the AP-42 and EPA emission factors are based on brake HP. For NOx and CO, the maximum hourly emissions (lbs/hr) are

calculated based on the stack test emission factors and the maximum generator electric output of 3600 KW as the stack test factors are based on the actual KW

generated.

[13] Annual emissions are calculated similar to maximum hourly emissions except that annual average load% is applied, and emissions are based on annual operating

hours.

[14] An average BSFC of 7,000 Btu/hp-hr was used to convert from lb/MMBtu to lb/hp-hr to calculate emissions.

[15] The emission factor for CO 2 is based on AP-42 Section 3.4. Large Stationary Diesel and All Stationary Dual-fuel Engines, October 1996. The emission factors for

CH 4 andN 2 O are based on Inventory of U.S. Greenhouse Gases and Sinks: 1990-2008 (April 2010), U.S. EPA # 430-R-10-006, Annex 3, Table A -81. Emission factor

for CO 2 e calculated using the GWPs obtained from 40 CFR 98.
