Title: Emission Outlook for Industry'


1
Tasks Performed.
  • Emission Outlook for Industry.
  • Marginal Abatement Cost Curves for
    Industry.(Adjustment of existing detailed MACs
    for regions where little information was
    available).
  • Exploration of abatement Potentials.

Emission Outlook
HFC Sources HFC 134a is used as a refrigerant in
motor vehicle air conditioners also HFCs are used
in in foams and aerosols and from 1994 these
compounds also found applications as solvents.
HFC-23 is generated as a byproduct during the
production of (HCFC-22). Outlook Assumptions The
hfc emissions as ods substitutes increased
dramatically due to efforts to phase out cfc and
other ods. Nearly all producers in developed
countries have implemented process optimization
or thermal destruction to reduce HFC-23
emissions. Emissions are expected to continue
decreasing because HCFC-22 production, is
scheduled to be phased-out by 2030.

Emission Outlook.
  • N2O Sources
  • Nitrous Oxide is emitted during the production of
    both adipic and nitric acid (adipic acid is
    mainly used in the production of nylon - nitric
    acid is a major component of adipic acid.
  • Outlook Assumptions
  • 1)Shifts in chemical production to developing
    countries.
  • 2)Decrease in nitric acid demand 3)Aggreement of
    the major adipic acid producers to a voluntary
    reduction of their emissions by the end of 2000.

Emission Outlook.
PFC Sources Semiconductor manufacturing.(mainly
from the US, EU-15, and Japan),Solvents,Aerosols.
Outlook Assumptions Market demand for
semiconductors is projected to continue its
current rapid growth until 2010. Correspondingly,
a rapid growth in PFC emissions from the
semiconductor industry is projected for this
period. In April 1999, the World Semiconductor
Council (WSC) agreed to reduce PFC emissions.
6
Emission Outlook.
  • PFC Sources
  • Aluminium production is the largest source of
    PFCs (the magnitude of the emissions depends on
    the frequency of the anode effects).
  • Outlook Assumptions
  • Reductions in domestic aluminium production and
    actions taken to reduce the frequency and
    duration of anode effects (Voluntary Aluminium
    Industrial Partership.). The production growth
    results from additions to current aluminum
    capacity, mostly in the developing world, and
    improvements in cell technology that increase
    production efficiency at existing smelters
    worldwide. Emission rates, on the other hand, are
    expected to decrease as upgrades in process
    controls and alumina feeding systems will yield
    shorter, less frequent anode effects. The
    developed countries as a whole will see a
    substantial decrease in emissions because of the
    combined effect of production moving to
    developing countries and reduced emission rates.

Emission Outlook.
  • Emissions Sources
  • Cement manufacture results in the generation of
    carbon dioxide.The largest source of industrial
    co2 (non energy related) emissions is the cement
    production.
  • Outlook Assumptions
  • Anticipated Increase in Cement Production.

8
Emission Outlook.
  • Emissions Sources
  • The magnesium metal production and casting
    industry uses sulfur hexafluoride (SF6) as a
    cover gas to prevent the violent oxidation of
    molten magnesium in the presence of air.The
    industry adopted the use of SF6 to replace sulfur
    dioxide (SO2). SF6 is also emitted during the
    production of aluminium.
  • Outlook Assumptions
  • Voluntary SF6 Emission Reduction Partnership for
    the Magnesium Industry. Shift of aluminium
    production in the developing world,

2030.Total 2595 CO2 eq.

Abatement Technologies.
  • N20 from Chemical Industry
  • 1) Process Integrated measures that require new
    plants.
  • 2) End of pipe measures Emissions can be
    reduced through end of pipe equipment based on
    catalytic conversion .
  • HFC from Other Industries
  • 1) Process Optimization Process optimization
    and modifying production equipment can both
    optimize HCFC-22 production and reduce HFC-23
    emissions. Process optimization is relatively
    inexpensive and is likely to be most effective in
    reducing the emissions from plants that are
    generating HFC-23 at a rate of 3 to 4.
  • 2) Thermal Oxidation It has been estimated that
    the total installed capital costs for a thermal
    oxidation system are approximately 7 million per
    plant with total annual operational costs of
    200,000 per year (Honeywell, 2000) (30
    reduction).
  • CO2 from non metallic minerals
  • 1) Blended cements', using such ingredients as
    coal fly ash, where the CO2 emissions are
    slightly suppressed, by a maximum of 10-15.
    There is no known technology to reduce carbon
    dioxide emissions of Portland cement any further.

11
Abatement Technologies
  • SF6 from Other Industry
  • 1) Capture/Recycle SF6 Air Liquide developed
    an SF6 capture/recycle system that could reduce
    SF6 emissions by up to 95 percent from current
    levels (Li, 2000). The captured SF6 can be
    re-used by the industry onsite.
  • PFC from Other Industry
  • 1) PFC Capture/Recovery. Currently available
    capture systems are guaranteed to remove 90
    percent of emissions.
  • PFC from non ferrous metals
  • 1) Improving Alumina Feeding Techniques.
  • Using Improved Computer Controls to optimize cell
    performance (30 reduction).
  • Training Cell Operators on methods and practices
    to minimize the frequency and duration of AEs.
