PRE-COMBUSTION CARBON CAPTURE TECHNOLOGIES FOR COAL-BASED GASIFICATION PLANTS -- Topic Area 2: High-Efficiency Solvents: NOTE: This descriptive area provides an overview of Topic Area of Interest 2 only. YOU MUST READ THE ENTIRE FUNDING OPPORTUNITY ANNOUNCEMENT DOCUMENT FOR ADDITIONAL INFORMATION, EVALUATION CRITERIA AND INSTRUCTIONS ON HOW TO PREPARE AN APPLICATION UNDER A SPECIFIC TECHNICAL TOPIC AREA OF INTEREST. Please scroll to the bottom of this page to access the Funding Opportunity Announcement. Topic Area 2 High Efficiency Solvents: High efficiency solvents, physical, chemical, or hybrid, refer to capturing CO2 at high temperature and high CO2 partial pressures and low energy requirement to restore the solvent, thus reducing capital costs and making the capture of the CO2 more energy efficient and cost-effective. With respect to IGCC, pre-combustion capture is advantageous because of the high partial pressure of CO2 and capture at higher temperatures, as compared to cooler conventional scrubbing temperatures, thus providing a thermal efficiency advantage and potentially resulting in lower parasitic power load. Physical absorption, as with current physical solvents, has temperature and pressure dependence with absorption occurring at low temperature and high pressure, and is more applicable for feeds with high CO2 partial pressures. The CO2 is released at near atmospheric pressure, requiring recompression for transportation to storage sites. The solvents are regenerated by heating, or pressure reduction, or both. The interaction between CO2 and the absorbent is weak relative to chemical solvents thus decreasing the energy requirement for regeneration, a topic area objective. Capacity can be higher than chemical solvents, since it is not limited by the stoichiometry of the chemical system. Capacity improvement is also a topic area objective. CO2 capture by physical solvents is believed to occur by two mechanisms namely, solvent-solvent and CO2-solvent interactions. Maximizing the later parameter might allow good cohesion between CO2 and the solvent molecules in high-efficiency solvents and improve CO2 uptake. The attractive physical solvents for CO2 capture are those having such properties as high thermal stability, low vapor pressures, non-flammability, and non-toxicity. Such materials can capture CO2 with minimal solvent loss in the gas stream, and are expected to be environmentally benign. High-efficiency solvents with higher volumetric capacity and selectivity for CO2 compared to conventional physical solvents are of interest. Chemical absorption of CO2 occurs by acid base neutralization and is a suitable method for the separation of CO2 from exhaust gases, when CO2 has a low concentration in a gaseous stream at atmospheric pressure and low temperature, followed by the recovery of CO2 from chemical solvents by using low-grade heat, usually extracted from power plants. Problems of scale, efficiency, and stability are issues with chemical solvents for high volume gas flows with a relatively smaller fraction of the product to be separated. The processes require large amounts of solvents undergoing significant changes in conditions, leading to high investment costs and energy consumption, and solvents degrade and oxidize over time, and may be corrosive. For Topic Area 2, applications are sought for R D leading to optimal performance of novel, high-efficiency solvents allowing step-change reduction in energy requirements compared to conventional solvents. Advanced solvents with good absorption and desorption characteristics and those which oxidize slower, and hybrid solvents (mixed chemical-physical solvents) which can combine physical and chemical mechanisms to exceed the CO2 volumetric capacity of current solvents are of interest. Research and engineering development with respect to design and operating criteria including parasitic energy consumption, equipment size, by-products formation, appropriate hydraulic and process parameters, the thermodynamics and kinetics of the system, and performance, cost, and rate-based models of the capture system are of interest. Preliminary process systems analyses with integration schemes of the capture system in IGCC-CCS plants as well as energy recuperation along with recommendations for the design and manufacturing assessments of the solvent-based pre-combustion CO2 capture systems based on the R D results and system analyses are desired. In responding to the Topic Area 2, the applicant shall demonstrate a thorough understanding of the technology being proposed. The applicant shall describe, if applicable, the current level of performance of the proposed technology relative to CO2 capture efficiency and the path forward by the proposed approach to achieving DOE's Carbon Sequestration performance goal, available on DOE/NETL website (http://www.netl.doe.gov). The applicant shall provide information relevant to overcoming the key technical challenges and barriers discussed above and anticipated during the conduct of the technology R D efforts. The proposed R D shall be conducted according to a planned approach, including but not limited to the work such as suggested below, and the technical strategy modified and work emphasis shifted as necessary to accomplish the FOA Topic Area 2 objectives: Identify the most favorable high efficiency solvents, absorption device designs, solvent recovery, technology validation, and conceptual integration schemes with appropriate components of future IGCC-CCS power production systems; Perform tests on simulated WGS mixtures at commercially-relevant conditions and complete appropriate data interpretation and analyses. The data and results shall be presented in a format and engineering units suitable for engineering development and scale-up; Using the data from above, provide an analysis with details sufficient to permit a preliminary economic evaluation of the process and its scale-up and commercial potential.
