As is evident from the table, the abatement costs are significant, especially for energy' intensive MSF plants. Vertical pumping requires 0.36 kWh/m3/100 m (derived in the transport section). Horizontal pumping requires much less energy, typically of the order of 0.04 kWh/m3/100 km. The energy, C02 emissions and abatement costs from the vertical and horizontal pumping components are presented in tables 8 and 9.
