Book Description
The NOXSO process is a dry, post-combustion flue gas treatment technology which uses a regenerable sorbent to simultaneously adsorb sulfur dioxide (SO2) and nitrogen oxides (NOx) from the flue gas of a coal-fired utility boiler. In the process, the SO2 is reduced to elemental sulfur and the NOx is reduced to nitrogen and oxygen. It is predicted that the process can economically remove 90% of the acid rain precursor gases from the flue gas stream in a retrofit or new facility. The objective of the NOXSO Demonstration Project is to design, construct, and operate a flue gas treatment system utilizing the NOXSO process at Ohio Edisons̀ Niles Plant Unit {number_sign}1. The effectiveness of the process will be demonstrated by achieving significant reductions in emissions of sulfur and nitrogen oxides. In addition, sufficient operating data will be obtained to confirm the process economics and provide a basis to guarantee performance on a commercial scale. Ohio Edisons̀ Niles Plant Unit {number_sign}1 generates 115 MW of electricity and 275,000 scfm of flue gas while burning 3.5% sulfur coal. The project is presently in the project definition and preliminary design phase. This phase was included in the project to allow completion of process studies and preliminary activities which could be conducted in parallel with NOXSOs̀ pilot plant project being conducted at Ohio Edisons̀ Toronto Power Plant.

Book Description
The NOXSO process is a dry, post-combustion flue gas treatment technology which uses a regenerable sorbent to simultaneously adsorb sulfur dioxide (SO2) and nitrogen oxides (NO3 from the flue gas of a coal-fired utility boiler. In the process, the SO2 is converted to a sulfur by-product and the NO3 is converted to nitrogen and oxygen. It is predicted that the process can economically remove 90% of the acid rain precursor gases from the flue gas stream in a retrofit or new facility. The objective of the NOXSO Demonstration Project is to design, construct, and operate a flue gas treatment system utilizing the NOXSO process. The effectiveness of the process will be demonstrated by achieving significant reductions in emissions of sulfur and nitrogen oxides. In addition, sufficient operating data will be obtained to confirm the process economics and provide a basis to guarantee performance on a commercial scale. The project is presently in the project definition and preliminary design phase. Data obtained during pilot plant testing which was completed on July 30, 1993 is being incorporated in the design of the commercial size plant. A suitable host site to demonstrate the NOXSO process on a commercial scale is presently being sought. Preliminary engineering activities involved evaluating various design options for the major process vessels with the principal focus being on the sorbent heater vessel, which is operated at the highest temperature. Additionally, the impact of the NOXSO system on power plant particulate emissions and opacity was estimated. It is predicted that particulate emissions will decrease slightly while opacity will increase slightly. Neither change will be significant enough to have an impact on emissions compliance. Advertised performance of the proposed adsorber separator is being verified by laboratory testing. Process studies activities included POC equipment inspection and materials evaluations.

A suitable host site to demonstrate the NOXSO process on a commercial scale is presently being sought. The plant general arrangement has been revised to incorporate principles used in the design of fluidized catalytic cracking (FCC) plants. A NOXSO plant availability analysis was prepared using operating experience from the recently completed pilot plant as a basis. The impact of water desorption in the sorbent heater and water adsorption in the sorbent cooler has been quantified and incorporated into the NOXSO process simulator. NOXSO process economics has been updated based on the present design. Capital cost for a 500 MW plant designed to remove 98% of the SO2 and 85% of the NO3 is estimated at $247/kW.

A suitable host site to demonstrate the NOXSO process on a commercial scale is presently being sought. Preliminary engineering studies provided information to decide on the basic plant arrangement. A scaled up POC design was selected as the general arrangement of choice based on a cost versus technical risk assessment. The first step in developing an adsorber computer simulation was completed. Several processes for producing liquid SO2 from the regenerator offgas were developed and evaluated. It was concluded that the Claus and burn process which involves making elemental sulfur as an intermediate product was the best choice. The NOXSO process computer simulation was updated to include semi-plug solids flow through the fluidized beds of the sorbent heater and cooler. Heat loss calculations were also added.

Book Description
This environmental assessment (EA) was prepared to evaluate the potential impacts of a proposed demonstration project to be cost-shared by DOE and NOXSO Corporation under the terms of Clean Coal Technology (CCT) Demonstration Program. The project would demonstrate the NOXSO flue gas treatment technology, which is designed to reduce sulfur dioxide (SO2) and nitrogen oxides (NO3 emissions from existing coal-fired electric generating units. Its objective is to introduce advanced, efficient, reliable, and environmentally improved coal utilization technologies to the U.S. energy marketplace, in order to reduce or eliminate economic and environmental barriers to the continued use of coal as an energy source. This EA represents the third level of DOEs̀ NEPA strategy: the preparation and public distribution of NEPA documents for each project selected for financial assistance under the PON. It contains a site-specific environmental impact analysis of the proposed federal action, and will result in either a Finding of No Significant Impact, or a determination that significant impacts may occur, in which case an Environmental Impact Statement must be prepared. The sources of information for this EA include the technical proposal for the project submitted by NOXSO in response to the CCT Round III PON; discussions with NOXSO and their consultants; discussions with federal, state and local agencies; the April 1995 NOXSO Environmental Information Volume provided to DOE for the project; and visits to the proposed project sites.

Book Description
The objective of the NOXSO Demonstration Project (NDP), with cost-shared funding support from DOE, is to design, construct, and operate a commercial-scale flue gas cleanup system utilizing the NOXSO process. The NDP consists of the NOXSO plant and sulfur recovery unit, designed to remove SO[sub 2] and NO[sub x] from flue gas and produce elemental sulfur by-product, and the liquid SO[sub 2] plant and air separation unit, designed to process the elemental sulfur into liquid SO[sub 2]. The NOXSO plant and sulfur recovery unit will be constructed at ALCOA Generating Corporation's (AGC) Warrick Power Plant near Evansville, Indiana, and will treat all of the flue gas from the 150-MW Unit 2 boiler. The elemental sulfur produced will be shipped to the Olin Charleston Plant in Charleston, Tennessee, for conversion into liquid SO[sub 2].
