Influence of the Selected Parameters on the Effectiveness of IGCC System Integrated With CCS Installation

Abstract

The paper presents the basic input data and modelling results of IGCC system with membrane CO 2 capture installation and without capture. The models were built using commercial software (Aspen and GateCycle) and with the use of authors' own computational codes. The main parameters of the systems were calculated, such as gross and net power, auxiliary power of individual installations and efficiencies. The models were used for the economic and ecological analysis of the systems. The Break Even Point method of analysis was used. The calculations took into account the EU emissions trading scheme. Sensitivity analysis on the influence of selected quantities on break-even price of electricity was performed.

Comparison of carbon capture IGCC with chemical-looping combustion and with calcium-looping process driven by coal for power generation

“…where C E represents equipment cost with capacity Q; C B represents the base cost with capacity Q B , which can be derived from published cost data (Black, 2010;Cormos, 2012bCormos, , 2014Olaleye and Wang, 2014); M represents the constant varying on equipment type, and M typically assumed in the range between 0.6 and 0.7 (Skorek-Osikowska et al, 2014).…”

Thermo-economic investigation: an insight tool to analyze NGCC with calcium-looping process and with chemical-looping combustion for CO2capture

“…where C E represents the capital cost of plant sub-system with capacity Q, $; C B denotes the capital cost of plant sub-system with capacity Q B , $, and it is derived from existing literatures [43][44][45][46]; M represents a constant, which is typically assumed in the range between 0.6 and 0.7 [47]. The market prices, basic parameters, and assumptions for calculating economic indicators regarding all cases are summarized in Table VII [43][44][45][46][47][48][49][50]. It should be noted that the market and utility prices mentioned herein are solely used as the base case for calculations assigned to the unstable price.…”

Investigation of a combined gas-steam system with flue gas recirculation

“…This results in a significant increase in CO 2 concentration in flue gases, which facilitates the gas further processing and condensation of water. This method is associated with the use of energy-intensive membranes separating O 2 from the air (Skorek-Osikowska et al, 2014).…”
