Alternatives for the reduction of sulfur oxide emissions from an existing 1300-MW coal-fired electric power station are compared with respect to technological feasibility, practicality, and cost. The two principal options available for near-term (1975-1977) application are (1) low-sulfur fuel oil derived from petroleum, and (2) low-sulfur western coal. Low-sulfur fuel oil is technologically practicable now, but the long-term outlook is for continued scarcity, high price, and unreliability of supply.
