CO2 capture RD&D proceedings in China Huaneng Group

Abstract

CO 2 capture is an important carbon management route to mitigate the greenhouse gas emission in power sector. In recent years, China Huaneng Group (CHNG) has paid more attention on CO 2 capture technology development and launched a series of R&D and demonstration projects. In the area of pre-combustion CO 2 capture technology, GreenGen project initiated by CHNG is the first integrated gasification combined cycle (IGCC) power plant in China. Located in Tianjin, GreenGen aims at the development, demonstration and promotion of a near-zero emissions power plant. An IGCC plant of 250 MW has successfully passed full-scale trial operation. In the next phase, a pre-combustion CO 2 capture unit will be integrated into the system. Pre-combustion process based on coal chemical process has been developed with lower costs successfully. Regarding to post-combustion CO 2 capture (PCC), in 2008, CHNG built a 3,000 tpa CO 2 capture plant, which was the first CO 2 capture demonstration plant in China. In 2009, CHNG launched a PCC project in Shanghai with a capture capacity of 120,000 tpa CO 2 . Recently, Huaneng Clean Energy Research Institute (CERI) and Powerspan formed a joint venture, Huaneng-CERI-Powerspan (HCP). HCP has completed the technology qualification program to supply carbon capture technology for the CO 2 capture Mongstad project. Besides these activities mentioned above, feasibility studies and system design for large scale PCC system, have been undertaken by CERI and its partners from Australia, US and Europe.

Novel Process of Removal of Sulfur Dioxide by Aqueous Ammonia–Fulvic Acid Solution with Ammonia Escape Inhibition

“…Typically the flue gas from coal-fired power plant contains around 4% O 2 , so the effect of the O 2 volumetric concentration on SO 2 absorption should be also taken into account. Under the same experimental condition, the volumetric concentration of O 2 was varied from 0 to 10%, and its effect on SO 2 absorption is shown in Figure .…”

Coal Bed Methane Enhancement Techniques: A Review

“…Hydraulic fracturing, coal dissolving using solutions and porosity increase can increase coal available surface area for decomposition. [218][219] Increasing bioavailability of coal organics-Decomposition of coal to intermediates is considered as a rate determining step. Kinetics of this step can be catalysed by solvents (such as alcohols) [220] and some surfactants & biosurfactants.…”

Post-synthesis modification of porous organic polymers with amine: a task-specific microenvironment for CO2 capture

“…The rapidly increasing concentration of atmospheric carbon dioxide generated from combustion of fuels (include coal, petroleum and natural gas) has aroused environmental concern, as a result, carbon capture and sequestration (CCS) gradually gain their growing popularity (D'Alessandro et al 2010;Sumida et al 2011;Goeppert et al 2012;Lu et al 2013;Wang and Xu 2014;Romanov et al 2015). Chemical absorption by aqueous solutions of ethanolamines (Brennecke and Gurkan 2010), which is most widely used CCS technique, suffer from several fatal defects including solvent loss, corrosion, and tremendous energy cost for the regeneration (Service 2004).…”
