Cost and performance of some carbon capture technology options for producing different quality CO2 product streams

摘要: Abstract A techno-economic assessment of power plants with CO2 capture technologies a focus on process scenarios that deliver different grades product purity is presented. The three leading are considered, namely; oxyfuel combustion, pre-combustion and post-combustion capture. study uses combination simulation flue gas cleaning processes, modelling plant cost performance calculator literature values key criteria in order to evaluate the performance, considered options. For combustion plants, raw processing strategies compression dehydration only, double flash system purification distillation considered. Analysis options based integrated gasification combined cycle using physical solvent systems for capturing sulfur species via routes; co-capture impurities stream Selexol™ solvent, separate Selexol™, Rectisol® CO2. was made without some conventional pollution control devices. results highlight wide variation scenarios. devices offers high (99.99 mol%) average technologies. calculations performed will be use further analyses whole chain CCS safe economic capture, transport storage
