3Emissions Emission….?? Emissions are caused due to some reactions either on the surface or underground. Sometimes these emissions are harmful and dangerous to the environment and
create a pollute environment which further results in health problems.
4Emissions Associated with DrillingOil and gas drilling activities require equipment and materials to perform different operations. Generally, drilling involves the road construction and other infrastructure. The essential activities: Pad, Impoundment and Road Construction(truck traffic) Drilling Rigs Fracturing Flaring Condensate Tanks Compressor Stations Pipeline Leakage
5Explosions and Fires Explosion : due to the ignition of flammable gases or vapors. Emissions : well gases, vapors and hydrogen sulfide. Sources: Wells, trucks production equipment or surface equipment i.e. shale shakers and
tanks.
6Key Facts of Drilling Phase• Fracking Provides Many Opportunities For The Release Of Air Pollutants.
• Pipeline Leaks Are Main Contributor For Methane Emissions; Fracking Growing Contributor.
• EPA: Emissions From Drilling, Including Fracking, And Leaks From Transmission Pipes, Totaled 225 Million Metric Tons Of Carbon-Dioxide Equivalents During 2011, Second Only To Power Plants.
• Truck Emissions Carrying Materials To And From Sites Increase Air Pollution Around Fracking Operations.
• Increased Emissions Caused By More Fracking Could Speed Climate Change.
7Some Drilling Activities
8Emissions Likelihood Depends upon field characteristics, well depth, density and geological surrounding of
the producing formation. Venting releases methane and other hydrocarbons, including volatile organic
compounds and hazardous air pollutants. Methane has approximately 21 times the global warming potential of carbon dioxide.
9Planning and PreventionEach company should have its own safety programme : Know the Hazard Establish ways/methods Provide PPE’s Communicate the hazards
10Emissions from Production facilities Oil and natural gas production facilities emit pollutants such as hazardous air
pollutants (HAPs) and volatile organic compounds (VOC). These pollutants can contribute to health problems that may affect facility employees and the community. While Federal, state, local, and Tribal regulations limit the amount of emissions from oil and natural gas production facilities, dangerous releases of HAPs can occur if an oil and natural gas production facility does not operate in compliance with regulations.
11Emissions during O&G Production
Oil and natural gas production emits benzene, toluene, ethylbenzene, and xylenes (BTEX) as well as n-hexane and VOC.
Benzene Exposure to benzene may cause
Irritation of the skin, eyes, and upper respiratory tract.Blisters on the skin.
Exposure to benzene over a long period of time may cause blood disorders, reproductive and developmental disorders, and cancer.
12Other Pollutants and EffectsEmissions Effects
Toluene Irritation of skin, respiratory tract, headaches
Ethyl Benzene Throat and eye irritation, chest constriction
Xylenes Irritation of the nose and throat, vomiting
N-Hexane Dizziness, giddiness, and headache
VOC’s Breathing difficulties (asthma)
13Emission Reduction Techniques
Make Connections Make a Plan Locate Resources Reward Facilities
14Emissions during Storage
15LPG (Liquefied Petroleum Gas) A Clean Fuel. Mixture of Propane, Propylene, Butane and Butylene. Three Grades of LPG: Commercial grade propane Engine fuel-grade propane Commercial grade butane
16Emissions during LPG Plant Operation NOx, CO, Volatile Organic Compounds and SO2.Methane (CH4), CO2, and Nitrous oxide (N2O).
Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) emissions are all produced during LPG combustion.
17Factors affecting emissions Burner design Burner Adjustment Boiler Operating Parameters, and flue gas venting Improper design, blocking and clogging of the flue vent, and insufficient combustion air result in improper combustion and the emission of
aldehydes, CO, hydrocarbons, and other organics.
