H. Schütz, MFA training workshop 31.8.07

EW-MFA Training Workshop – 31. August 2007

Training Session: -Balancing items and NAS – Net Additions from Stock

H. Schütz, MFA training workshop 31.8.07

Balancing items and NAS - Intro

Correct for inconsistent accounting of inputs and outputs to derive consistent material balance

H. Schütz, MFA training workshop 31.8.07

Balancing items and NAS – Input side

Oxygen for combustion processes-> based on air emission data -> requires to account in addition for H content in energy carriers -> requires to account for net demand (less oxygen content of energy carriers)

Include real oxygen demand for production – steel production

Exclude CO2 emissions from cement and lime production (intrinsic CO2)

Oxygen for respiration - coefficients Nitrogen for Haber-Bosch – estimate Nitrogen for NO, NO2 emissions – feasible?

H. Schütz, MFA training workshop 31.8.07

Balancing items and NAS – Output side

Water vapour from fuels -> requires to account for H2O content in energy carriers

Water vapor from oxidised hydrogen in fuels -> based on H accounted at input side

CO2 and H2O from respiration of humans and livestocks – coefficients
