Life cycle assessment comparison of technical solutions for CO2 emissions reduction in power generation

摘要: An exergetic life cycle assessment (ELCA) and a classical environmental (LCA) have been performed for three carbon dioxide low emission power cycles. The configuration of the cycles are: semi-closed gas turbine combined with CO2 reduction from exhausts by means amine solution chemical absorption; an integrated gasification synthesis O2/CO2 innovative where, burning methane in oxygen, becomes working fluid, excess, produced combustion, is removed liquid phase without any additional system. LCA mainly focussed on production during phases construction, operation dismantling plants. This necessary to verify if process effective terms reduction. Besides classic LCA, also ELCA was performed, whose aim assess cost, exergy losses, plants. The lifetime, sort classification studied plant obtained.
