Integrated Gasification

Integrated Gasification Combined Cycle and Pressurized Fluidized-Bed Combustion power systems have made it possible to use coal while still protecting the environment. Such power systems virtually eliminate the pollutants associated with coal-fired plants built before the 1970’s. Superior environmental performance and high system efficiency requires that gas stream cleanup be conducted under high temperature and high pressure process conditions. To realize this high system efficiency, particulate cleanup levels must meet gas turbine particulate tolerance limits. Discussed below are some of the particulate cleanup requirements and challenges for these advanced power systems. Also presented is the work underway to support particulate cleanup technology and the Clean Coal Technology (CCT) Program through pilot-scale testing and filter component development.

The U.S. Department of Energy’s Office of Fossil Energy Turbine Program is implementing a new research program to develop turbines for integrated gasification combined cycle (IGCC) systems that capturer CO2. On September 8, 2005 the U.S. DOE Office of Fossil Energy announced a $130 million investment of government money in turbine related technology to promote the development of IGCC power systems that can capture CO2 and minimize the emissions of criteria pollutants. These funds will be matched at various levels by the industry partners. In part through this investment the FE Advanced Turbine Program is designed to attain three primary goals: 1) By 2010 develop advanced coal based power systems capable of 45–50% efficiency at < $1000 / kW, 2) By 2012, develop technologies for capture and sequestration of carbon dioxide that result in less than 10 percent increase in the cost of electricity and 3) By 2015 demonstrate coal based energy plants that offer zero emissions (including CO2) w/ multi product production. The program has an additional primary objective to provide turbine based technology for the FutureGen Project. To attain these goals the program is organized into four areas: H2 fueled turbines for IGCC and FutureGen applications, Oxy-fuel turbines for IGCC and FutureGen applications; MW-scale H2 fueled turbines and CO2 compression technology. The paper will report on the program goals, status of these new projects and early progress towards these goals and objectives.

Under the sponsorship of the U.S. Department of Energy/National Energy Technology Laboratory, a multidisciplinary team led by the United Technologies Research Center (UTRC) has identified a high performance biomass gasification/combined cycle system using Refuse Derived Fuel (RDF) as the major fuel resource. The system consists of fuel receiving/preparation/feed, advanced transport gasifier, high temperature gas cleanup and Pratt & Whitney Power Systems FT8 aero-derivative gas turbine with heat recovery steam generator and steam turbine. One of the team members, Connecticut Resource Recovery Agency (CRRA), currently processes approximately 2200 tons/day of municipal solid waste and delivers 1825 tons/day of RDF “across the fence” to a nominal 65 MWe steam plant. Based on the characteristics of the RDF from this plant, an 80 MWe combined cycle system having an estimated efficiency of 45% (RDF in/kW out) was identified. Other advanced cycle variations had even greater performance potential. The resulting cost of electricity for the biomass integrated gasification combined cycle (BIGCC) is competitive with that of natural gas fueled combined cycles, and the plant is projected to meet or exceed all environmental requirements.

Integrated Gasification

The Power Systems Development Facility (PSDF) is an engineering scale demonstration of advanced coal-fired power systems and high-temperature, high-pressure gas filtration systems that would be integral to an improved coal-fired power plant having efficiencies well over 40%, while exceeding all current emission standards for coal-fueled plants. The paper will describe such a plant before expanding the discussion on the operational experiences of the Kellogg Brown & Root, Inc. (KBR) Transport Reactor and the Siemens Westinghouse Power Corporation (SWPC) high-temperature gas filter system currently being demonstrated at the PSDF. A short survey of the process advantages (capital, operational, efficiency, and reliability) over current Integrated Gasification Combined Cycle (IGCC) plant designs, including hot gas clean-up, air-blown gasification, non-slagging gasifier operation and equipment commonality with existing pulverized coal power plants, will be highlighted; as will the potential of the power plant to be retrofitted in response to future carbon capture requirements.

The Cost

One of the ways to environmentally friendly use coal is an integrated gasification combined cycle. The most common oxidizing agent employed in gasification is oxygen. It is feasible to use air instead of oxygen to reduce the cost of generated electricity. The air gasification downsides can be reduced by using heated air and organizing a staged process. The paper is concerned with a thermodynamic analysis of the MHPS (Mitsubishi Hitachi Power Systems) air-blown staged gasifier. The analysis relies on an original approach that suggests investigating experimental data on a set of calculated ones. The experimental run nears the thermodynamic optimum, which coincides with the carbon boundary line. Cold gas efficiency can be increased from 78.6 to 81.5% by reducing the equivalence ratio. Thus, the temperature will decrease from 1 200 to 1 100 °C. The experimental run of the MHPS gasifier is not optimal thermodynamically, but it is probably optimal kinetically. The fact is that the rates of heterophase reactions decline near the carbon boundary, which leads to a sharp increase in fuel underburning and a decrease in efficiency. The experimental run is also located close to the region with the maximum thermal efficiency of the process, which is indicative of the high efficiency of converting air heat into chemical energy of producer gas.

The Cost

In this study a new multi-generation system which generates power (electricity), thermal energy (heating and cooling) and ash for agricultural needs has been developed and analysed. The system consists of a Biomass Integrated Gasification Combined Cycle (BIGCC) and an absorption chiller system. The system generates about 3.4 MW electricity, 4.9 MW of heat, 88 kW of cooling and 90 kg/h of ash. The multi-generation system has been modelled using Cycle Tempo and EES. Energy, exergy and exergoeconomic analysis of this system had been conducted and exergy costs have been calculated. The exergoeconomic study shows that gasifier, combustor, and Heat Recovery Steam Generator are the main components where the total cost rates are the highest. Exergoeconomic variables such as relative cost difference (r) and exergoeconomic factor (f) have also been calculated. Exergoeconomic factor of evaporator, combustor and condenser are 1.3%, 0.7% and 0.9%, respectively, which is considered very low, indicates that the capital cost rates are much lower than the exergy destruction cost rates. It implies that the improvement of these components could be achieved by increasing the capital investment. The exergy cost of electricity produced in the gas turbine and steam turbine is 0.1050 £/kWh and 0.1627 £/kWh, respectively. The cost of ash is 0.0031 £/kg. In some Asian countries, such as Indonesia, ash could be used as fertilizer for agriculture. Heat exergy cost is 0.0619 £/kWh for gasifier and 0.3972 £/kWh for condenser in the BIGCC system. In the AC system, the exergy cost of the heat in the condenser and absorber is about 0.2956 £/kWh and 0.5636 £/kWh, respectively. The exergy cost of cooling in the AC system is 0.4706 £/kWh. This study shows that exergoeconomic analysis is powerful tool for assessing the costs of products.
