Igcc Power Plant

Most of the scenarios presented by different actors and organizations in the energy sector predict an increasing power demand in the coming years mainly due to the world’s population growth. Meanwhile, global warming is still one of the planet’s main concerns and carbon capture and sequestration is considered one of the key alternatives to mitigate greenhouse gas emissions. The integrated gasification combined cycle (IGCC) power plant is a coal-derived power production technology which facilitates the pre-combustion capture of CO2 emissions. After the establishment of the baseline configuration of the IGCC plant with CO2 capture (reported in GT2011-45701), a techno-economic evaluation of the whole IGCC system is presented in this paper. Based on publicly available literature, a database was established to evaluate the cost of electricity (COE) for the plant using relevant cost scaling factors for the existing sub-systems, cost index, and financial parameters (such as discount rate and inflation rate). Moreover, an economic comparison has been carried out between the baseline IGCC plant, a natural gas combined cycle (NGCC), and a supercritical pulverized coal (SCPC) plant. The calculation results confirm that an IGCC plant is 180% more expensive than the NGCC. The overall efficiency of the IGCC plant with CO2 capture is 35.7% (LHV basis), the total plant cost (TPC) is 3,786 US$/kW, and the COE is 160 US$/MWh.

The Impact

A detailed economic evaluation was carried out to determine the impact of biomass and coal co-firing on power plant carbon capture by methods of plants equipment designing factors and performance, and the sum up of the associated breakdowns of CAPEX and OPEX. Based on the assumptions of the CO2 neutrality of biomass and likely governmental incentives to reduce CO2 emissions, the study results show that biomass and coal co-firing would result in both lower cost of carbon avoided (carbon capture) and lower incremental cost of electricity generation when MEA solvent carbon capture is applied. Two scenarios for co-firing with carbon capture, 30% biomass blending and 90% or 60% CO2 capture from stack, indicate different preference depending on lower or higher incentives.

Igcc Power Plant

Within this study energetic and exergetic theoretical analyses of a novel IGCC power plant concept with CO2 capture are carried out. The core process of the concept examined is based on the high pressure steam gasification of high moisture low grade coals where CO2 is captured reacting exothermically with CaO-based sorbents and high hydrogen-content carbon-free fuel gas is produced without using additional shift reactors and CO2 separation stages. The carbonated sorbents are continuously fed to an oxygen blown calcination reactor where pure CO2 is released and active CaO is reproduced. This concept can be realised in a dual fluidised bed reactor system where coal gasification and CaCO3 calcination are taking place simultaneously. In this paper possible plant configurations are presented and detailed simulation of 400 MWe IGCC power plant based on a state of the art gas turbine cycle with a three pressure stage heat recovery steam generator is performed using the ASPEN Plus simulator. The calculated results demonstrate the capability of the power plant to deliver almost decarbonised electricity while achieving net plant efficiencies at about 38.4% of coal lower heating value (LHV). Based on the energy analysis and the data generated from the simulation an exergy analysis was performed in order to quantify and localize the thermodynamic irreversibility in each process component as well as to asses the overall thermodynamic imperfection of the proposed process.
