2. Description
• Integrated Gasification Combined Cycle (IGCC)
Technologies discusses this innovative power generation technology
that combines modern coal gasification technology with both gas
turbine and steam turbine power generation, an important emerging
technology which has the potential to significantly improve the
efficiencies and emissions of coal power plants.
3. Introduction
• In order to find an economic and cost effective process of carbon
dioxide (CO2) separation and hydrogen (H2) purification from the
integrated gasification cycle combustion (IGCC) syngas, a hydrate-
based technology in conjunction with chemical adsorption method is
proposed in this work.
4. Introduction
• With power generation from gas turbine and steam turbine the purified
hydrogen gas is also used as a fuel.
9. • the LCV gas produced by an air-blown, coal-fueled, fluid bed gasifier
will differ significantly in composition from an oxygen-blown,
vacuum residue-fueled, entrained flow gasifier. The resulting gas
composition, flammability and calorific value work in concert to form
the basis for the combustion system design and response
10. • For efficient use of all these fuels, IGCC process gives the best results.
• An integral part of IGCC is Hydrogen Gas Purification.
• With the use of Gas & Steam turbine the production of hydrogen fuel
can increase the efficiency of the process up to 73%
• Hence, a strong understanding of gas purification is important for
maximization of profit.
