TPRI H2/CO2 Separation Separation methods Shortcoming Advantages Absorption Physical Bad absorption selectivity, CO2 can be separated only by so good absorbent decompressed and distilled, need little performance is the key regeneration energy. Chemical High energy penalty Good absorption selectivity, CO2 concentration can be up to 99.9%. Adsorption Pressure Limited sorbent capacity, Low energy penalty and simple Swing so need more sorbent and process Adsorption high automatization for (PSA) sorbent’s frequent desorption. Cryogenic High energy penalty and Simple principle bulky facilities Membrane Hard to get high Simple and compact facilities, so need concentration CO2 little space. It has good efficiency and flexibility, easy to operation and low cost. No additional pollution(the cost is 25% lower than absorption ) TPRI MeansMeans ofof GeologicalGeological SequestrationSequestration oror StorageStorage ofof COCO22 TPRI CO2 storage capacity in China COCO2 storagestorage inin deepdeep geologicgeologic formationformation andand TPRI enhanceenhance oiloil recoveryrecovery TPRI TPRI,GreenGen Co. joined the COACH and will join the cooperation with UK for CO2 capture and sequestration GeoCapacity COACH Geological map of the Bohai and Ordos Basins TPRI SummarySummary China needsneeds GreenGen Roadmap of GreenGen Program was ready in 2004 First stage demonstration project is based on the China’s intellective property, and will go into operation in 2009 Demonstration project is funded by MOST TPRI Thank you for your attention !
