Regenerative Flue Gas Desulphurization in European Oil Refineries - Cost Estimates Based on a European Application

摘要

The petroleum refinery at Schwechat, Austria commissioned in 1985 a Wellman-Lord regenerative flue gas desulfurization plant (FGD) to control emissions essentially from the power generating sector of the refinery. This experience is used to estimate costs of Wellman-Lord FGD which would be more representative for other European refineries. Costs are given for the Schwechat-size FGD (600,000 N cubic meters/h flue gas) and a typical refinery-size FGD (150,000 N cubic meters/h flue gas). It is concluded that FGD cost-effectiveness is better when refineries burn higher sulfur fuels but small plant size has a significant detrimental effect. Wellman-Lord FGD can more than double the cost of liquid refinery fuel.
