I E SEmission inventory for industrial sites

• A toolkit for
• atmospheric emissions inventory

• 
  IES Toolkit
• Drivers
• increased demand for accurate accounting of
  pollutant emissions into the atmosphere
• Integrated Prevention and Pollution Control
  (annual emissions)
• EMAS environmental reports
• Sustainability Reports
• Certification of GHG emissions in view of future
  Emission Trading Schemes
• need for a standardised, user-friendly and
  portable expert system to be used
• in a large number of worldwide sites
• by many users
• consistently over the years
• with a detailed and verifiable documentation

3

• IES Toolkit
• Special requirements with regard to greenhouse
  gases
• possible introduction of ET schemes within the
  next three years (e. g. proposal for a UE
  directive establishing a framework for greenhouse
  gas emission trading within the European
  Community)
• need of detailed data to better identify
  possible GHG reductions
• possible request for certification

4

• IES Toolkit
• In the Oil Gas sector special focus on GHG from
  gas flaring
• gas flaring accounts for a substantial share of
  GHG emissions by oil companies
• gas flaring represents about 12 of gross gas
  production
• oil companies industrial sites feature very high
  energy efficiency (cogeneration, heat cascading)
• zero gas flaring can give important contribution
  to Kyoto commitment

• 
  The goal
  of the IES toolkit is ...
• to provide a standardised methodology for
  accounting atmospheric emissions, within the Eni
  Group.
• Objectives
• to offer best practices for estimating/calculatin
  g/measuring pollutant atmospheric emissions
• to deal with controversial emissions (e.g.
  fugitive emissions)
• to achieve uniform data reporting
• to provide a detailed documentation of emission
  inventory

requirements?
Data collecting Reporting
completeness
uniformity accuracy
(appropriate methodologies)
transparency consistency
clarity certification

IES Development phases

• Identification of the Eni Group atmospheric
  emission sources for each sector of activity
  exploration production, refining marketing,
  petrochemical production, gas distribution, power
  generation
• Analysis of reporting needs
• Development of an equations database for each
  tern
• pollutant
• source
• fuel

GHG inventory

• The software is already developed to account for
  greenhouse gases (GHG) emitted from industrial
  sitesAttention is now focussed on a more
  accurate accounting of GHG related to natural gas
  flaring
• chemical composition
• (CH4, C1, N2, CO2, H2S)
• flaring efficiency
• gas flow
• emission factors
