TL;DR: In this article, a novel hydrogen pressure swing adsorption system has been studied that is applied to an advanced integrated gasification combined cycle plant for cogenerating power and ultrapure hydrogen with CO2 capture.
Abstract: A novel hydrogen pressure swing adsorption system has been studied that is applied to an advanced integrated gasification combined cycle plant for cogenerating power and ultrapure hydrogen (99.99+ mol%) with CO2 capture. In designing the H2 PSA, it is essential to increase the recovery of ultrapure hydrogen product to its maximum since the power consumption for compressing the H2 PSA tail gas up to the gas turbine operating pressure should be minimised to save the total auxiliary power consumption of the advanced IGCC plant. In this study, it is sought to increase the H2 recovery by increasing the complexity of the PSA step configuration that enables a PSA cycle to have a lower feed flow to one column for adsorption and more pressure equalisation steps. As a result the H2 recovery reaches a maximum around 93 % with a Polybed H2 PSA system having twelve columns and the step configuration contains simultaneous adsorption at three columns and four-stage pressure equalisation.

TL;DR: In this paper, the feasibility of clean gaseous fuels made from plastics, automobile tire rubber, municipal solid waste (MSW), and woody biomass feedstock using a high-temperature pure-steam gasification process was investigated.
Abstract: The main objective of this study is to investigate the feasibility of clean gaseous fuels made from plastics, automobile tire rubber, municipal solid waste (MSW), and woody biomass feedstock using a high-temperature pure-steam gasification process. Super-high-temperature steam at 1000 °C was used as the gasifying agent to generate the syngas which mainly contains hydrogen and carbon monoxide and can be used as a gaseous fuel. Since the process does not involve air, the syngas is free of nitrogen and its oxides which usually dilutes the syngas and lowers its heating value in the case of an air-blown partial-oxidation/partial gasification process. A lab-scale experimental apparatus was used to produce the high-quality syngas, and the gas was analyzed using a gas chromatography. The results showed that the syngas contained very high H2 concentrations, and the heating values of the syngas for all four types of feedstock reached 8–10 MJ/m3 which were approximately 2.5 times higher by weight and 1.6 times by vo...

TL;DR: In this article, the authors discuss coal-fired power plants, coal types, coal cleaning and processing, traditional coal-burning power plant technology such as boiler technology, and steam turbine design.
Abstract: This chapter discusses (1) coal-fired power plants, (2) types of coal, (3) coal cleaning and processing, (4) traditional coal-burning power plant technology such as boiler technology, and (5) steam turbine design. It also presents the emission control for traditional coal-burning plants, coal treatment, and environmental effects of coal combustion. Coal is the cheapest of fossil fuels—another reason why it is attractive to power generators. However, coal is expensive to transport; therefore, the best site for a coal-fired power plant is close to the mine that is supplying its fuel. The term coal embraces a range of materials. Within this range there are a number of distinct types of coal, each with different physical properties. These properties affect the suitability of the coal for power generation. Coal cleaning offers a way of improving the quality of coal, both economically and environmentally. The most well-established methods of coal-cleaning focus on removing excess moisture from the coal and reducing the amount of incombustible material that will remain as ash after combustion. Cleaning coal prior to combustion can significantly reduce the levels of sulphur emissions from a power plant, as well as reduce the amount of ash and slag produced. This can have a beneficial effect on plant performance and maintenance schedules. The chapter outlines the main approaches to physical coal cleaning.
TL;DR: In this paper, the authors evaluated the effects of coal quality and the selection of gasifiers on the overall performance of the baseline configuration of the integrated gasification combined cycle (IGCC) power plant delivering environmentally benign power from coal.
TL;DR: In this paper, the results of co-gasification tests with two types of biomass deriving from agricultural residues, namely 2% and 4% by weight of olive husk and grape seed meal, in the 335 MWeISO IGCC power plant of ELCOGAS in Puertollano (Spain) are reported.
Abstract: a b s t r a c t Integrated Gasification Combined Cycle plants (IGCC) are efficient power generation systems with low pollutants emissions. Moreover, the entrained flow gasifier of IGCC plants allows the combined use of other lower cost fuels (biomass and waste) together with coal. Co-firing with biomass is beneficial for the reduction of CO2 emissions of fossil source. In this paper the results of co-gasification tests with two types of biomass deriving from agricultural residues, namely 2% and 4% by weight of olive husk and grape seed meal, in the 335 MWeISO IGCC power plant of ELCOGAS in Puertollano (Spain) are reported. No significant change in the composition of both the raw syngas and the clean syngas was observed. Furthermore, a process simulation model of the IGCC plant of Puertollano was developed and validated with available industrial data. The model was used to assess the technical and economic feasibility of the process co-fired with higher biomass contents up to 60% by weight. The results indicate that a 54% decrease of fossil CO2 emissions implies an energy penalty (a loss of net power) of about 20% while does not cause significant change of the net efficiency of the plant. The mitigation cost (the additional cost of electricity per avoided ton of CO2) is significantly dependent on the price of the biomass cost compared to the price of the fossil fuel. © 2013 The Institution of Chemical Engineers.
