Cost and Performance Baseline for Coal-to-SNG and Ammonia (Volume 2)
This report establishes performance and cost data for coal fueled plants producing synthetic natural gas and ammonia. The plants are based on a dry-feed entrained-flow gasifier and include cases using bituminous, sub-bituminous, and lignite coals. All configurations were studied with and without carbon sequestration. The analyses were performed on a consistent technical and economic basis that accurately reflects current market conditions for plants starting operation in 2012. This is believed to provide the most comprehensive set of cost and performance data available in the public literature to date. The cost and performance data were compiled from published reports, information obtained from vendor quotes and users of the technology, and data from designing and building projects.

Independent Assessment of the Potential of Chemical-Looping in the Context of a Fischer-Tropsch Plant Simulations of an integrated coal to Fischer-Tropsch (F-T) liquids process, including a chemical looping scheme, under development by Ohio State University, were performed and the technical results from this analysis were then compared to a conventional coal-to-liquids (CTL) system. Results of the comparative technical analysis between the chemical looping scheme and the conventional CTL scheme indicate that the chemical looping case increased liquid production from the same coal feed by about 10% and the total carbon emissions per barrel produced is about 19% less for the proposed chemical looping system compared to the conventional CTL configuration.

Metal sorbents for high temperature mercury capture from fuel gas The paper “High temperature metal sorbents for mercury capture from fuel gas” was accepted for publication in the Elsevier Journal - Fuel.  It was found that palladium can adsorb large quantities of mercury from simulated syngas upon extended exposures, whereas platinum captured somewhat less mercury.  Sorbents with palladium concentrations of between 2 and 9% by weight on alumina were exposed to simulated syngas at temperatures of 204 oC – 371 oC.  X-ray diffraction analysis of the used palladium sorbents exposed at 204 oC suggests the formation of a mercury-palladium alloy, with concentrations of 12.0 - 14.4 atom percent mercury.  The large capacity for mercury by palladium sorbents bodes well for its commercial prospects in gasification systems.

Polygeneration of SNG, Hydrogen, Power, and Carbon Dioxide from Texas Lignite The intent of this study is to investigate the feasibility of siting a lignite conversion plant in Texas at the mine mouth of the Wilcox lignite deposit. The concept is to coproduce at least three products: electric power, hydrogen or substitute natural gas (SNG), and carbon dioxide. The electric power would be sold to the grid, the hydrogen would be sent by pipeline to the Gulf Coast petroleum refineries, the SNG would be sold as a natural gas supplement, and the carbon dioxide would be pipelined to the West Texas oil fields for enhanced oil recovery.

Capital and Operating Cost of Hydrogen Production from Coal Gasification Due to wide differences in reported cost for capital and the need to provide a baseline cost for hydrogen production, prior plant designs and cost estimates for producing hydrogen from coal gasification utilizing commercial technology have been reviewed and updated. The key benefit of utilizing commercial technology is obtaining credible cost estimates for the plant with a minimum of process contingency. The results of the effort are intended to prepare a basis from which to utilize individualized financial parameters in the U. S. Department of Energy Integrated Gasification Combined-Cycle Cost Estimating Model to arrive at a selling price for hydrogen. From a common thermal gasifier throughput, plant gate costs for hydrogen produced from coal gasification from two coals, Pittsburgh #8 bituminous and Wyodak Powder River Basin sub-bituminous, were determined from two plant designs for hydrogen production, based on currently available process technology, and meeting current permitting regulations for environmental compliance. These baseline plants will not capture CO2. These cost estimates were prepared to quantify the differing plant characteristics associated with bituminous coal or sub-bituminous coal.

The Cost of Mercury Removal in an IGCC Plant - Final Report This report estimates the cost of mercury removal for applying a carbon bed filter to an IGCC plant. The carbon filter bed is assumed to achieve 99 percent reduction of mercury emissions, with outlet levels less than 1 ppbw. The cost format was based on the methodology used in the EPA Mercury Study Report to Congress while the cost estimate (capital and O&M) was based on Parsons on-site data and experience. The costs of mercury removal by a carbon bed in an IGCC are found to be much lower than from a utility boiler with carbon filter beds.
