Title: SNOX flue gas cleaning demonstration project: A DOE assessment

Abstract

The goal of the US Department of Energy (DOE) Clean Coal Technology (CCT) Program is to provide the energy marketplace with a suite of advanced, cost-effective, highly efficient, and environmentally responsible coal-utilization technologies through cooperatively implementing a series of demonstration projects with industry stake holders. These projects seek to establish at scale the commercial viability of the most promising advanced coal technologies that have developed beyond the proof-of-concept stage. This document serves as DOE's post-project assessment of a project selected in CCT Round 2, SNOX{trademark} Flue Gas Cleaning Demonstration Project. DOE's participation in this project through Cooperative Agreement No. DE-FC22-90PC89655 is consistent with Public Law 100-202 as amended by Public Law 100-446. The SNOX process is a combination of catalytic processes that remove sulfur dioxide (SO{sub 2}), nitrogen oxides (NO{sub x}) and residual particulate matter (PM) from flue gas that has been pre-cleaned with particulate removal. The process generates salable sulfuric acid (H{sub 2}SO{sub 4}) meeting an industry wide standard (US Government Specification O-S-801E) from the SO{sub 2} and converts the NO{sub x} to harmless nitrogen and water vapor. The integrated design of the process enables high-pollutant-removal efficiencies, no significant waste production (only very low quantities of flue gas ashmore » and catalyst degradation fines), and significant heat recovery potential that can be used in the commercial application of the technology to attain increased thermal efficiency of the system. The host site chosen for this CCT demonstration project was Ohio Edison's Niles Station located along the Mahoning River in Niles, Ohio, just northwest of Youngstown. There are two cyclone coal-fired, steam electricity-generating units at the plant. The performance objectives of this project were as follows: to demonstrate SO{sub 2}-removal efficiency greater than 95%; to demonstrate NOx-removal efficiency greater than 90%; to demonstrate the commercial quality of the by-product H{sub 2}SO{sub 4}; to satisfy all Environmental Monitoring Plan requirements; to perform a technical and economic characterization of the technology.« less
