Gasification Technology

Integrated Gasification Combined Cycle (IGCC) is believed to be one of the most promising technologies to offer electricity and other de-carbon fuels with carbon capture requirement as well as to meet other emission regulations at a relatively low cost. As one of the most important parts, different gasification technologies can greatly influence the performance of the system. This paper develops a model to examine the feasibilities and advantages of using Ultra Superheated Steam (USS) gasification technology in IGCC power plant with carbon dioxide capture and storage (CCS). USS gasification technology converts coal into syngas by the endothermic steam reforming reaction, and the heat required for this reaction is provided by the sensible heat in the ultra superheated steam. A burner utilizes synthetic air (21% O2 and 79% H2O) to burn fuel gas to produce the USS flame for the gasification process. The syngas generated from USS gasification has a higher hydrogen fraction (more than 50%) then other gasification processes. This high ratio of hydrogen is considered to be desired for a “capture-ready” IGCC plant. After gas cleanup and water gas shift reaction, the syngas goes to the Selexol process for carbon dioxide removal. Detailed calculations and analysis are performed to test the performance of USS gasification technology used in IGCC generation systems. Final results such as net output, efficiency penalty for CO2 capture part, and net thermal efficiency are calculated and compared when three different coal types are used. This paper uses published data of USS gasification from previous research at the University of North Dakota. The model also tries to treat the IGCC with carbon dioxide capture system as a whole thermal system, the superheated steam used in USS gasification can be provided by extracting steam from the lower pressure turbine in the Rankine Cycle. The model will make reasonable use of various waste energies and steams for both mechanical and chemical processes to improve the performance of the plant, and incorporate CO2 capture system into the design concept of the power plant.

Abstract Operation of power plants in carbon dioxide capture and non-capture modes and energy penalty or energy utilization in such operations are of great significance. This work reports on two gas fired pressurized chemical-looping combustion power plant lay-outs with two inbuilt modes of flue gas exit namely, with carbon dioxide capture mode and second mode is letting flue gas (consists carbon dioxide and water) without capturing carbon dioxide. In the non-CCS mode, higher thermal efficiencies of 54.06% and 52.63% efficiencies are obtained with natural gas and syngas. In carbon capture mode, a net thermal efficiency of 52.13% is obtained with natural gas and 48.78% with syngas. The operating pressure of air reactor is taken to be 13 bar for realistic operational considerations and that of fuel reactor is 11.5 bar. Two power plant lay-outs developed based combined cycle CLC mode for natural gas and syngas fuels. A single lay-out is developed for two fuels with possible retrofit for dual fuel operation. The CLC Power plants can be operated with two modes of flue gas exit options and these operational options makes them higher thermal efficient power plants.

Removal System

This paper presents the study of a natural gas fired power cycle which includes a carbon dioxide capture plant based on an absorption and scrubbing system. The interest in this integration is due to the widespread use of combined cycles in the power generation sector because of their high energy conversion efficiency. Energy consumption of the capture and removal system and its influence on the energetic performance of the power plant have been calculated. Mass and heat balance calculations are carried out by using the software tools GateCycle for the combined cycle and Aspen+ Software for the absorption process. Results of plant performance calculations, including compression of the captured carbon dioxide, are presented. The results, compared to the combined cycle power plant with no carbon dioxide capture, have also been compared to the more commonly known carbon dioxide capture process based on atmospheric absorption with MEA.

The Impact

Abstract The impact of post-combustion carbon dioxide capture on the performance of a power plant is evaluated. A model of a coal power plant with post-combustion temperature swing adsorption CO2 capture using sorbent-loaded hollow fibers is presented. The resulting performance and cost of carbon capture are compared with those of other adsorption-based technologies. A parametric analysis of the performance of the power plant with respect to key parameters in the hollow fiber module operation is presented. It is found that electrical energy consumption for the compression of CO2 is a major parasitic load common to all absorption technologies and accounts for almost half of the total parasitic load. The effect of source temperature, flue gas fan and coupling fluid pump flow rates on overall system performance is presented. The impacts of different carbon capture technologies on the same coal-fired power plant are compared. Hollow fiber modules had the lowest parasitic load on the power plant, followed by KS-2 based carbon capture.
