Cost Effective Analysis of Reducing SO2 Emissions from Power Plants

Abstract

The aim of this work is to present and assess four alternatives for reducing sulfur dioxide emissions from thermal power plants. The 4 alternatives include using low-sulfur content fuels, installing flue gas desulfurization systems, switching to natural gas, and partially shifting to PV power.

An economic model was established to assess which of the alternatives is the most feasible. The model involves all costs and revenues associated with each of the alternatives. The model was also applied to the Zouk Lebanese power plant.

As there were plenty of uncertainties associated with various parameters, one-way and multiple sensitivity analysis were carried to assess which of the parameters had the biggest effect on the choice of technology to be used.

Results revealed that the natural gas alternative is the most economical for the Lebanese case in most scenarios. This alternative would be more appealing if this natural resource is found in Lebanese offshore territories, saving millions of dollars in purchasing and transporting.
