Analysis of CO2 capture performance with supplying the regeneration energy by in-bed heat transfer horizontal tubes in the dry sorbent CO2 capture system |
| 초록 |
Fluidized beds are widely used in many fields, where the heat transfer characteristics of those systems become principal for successful operation. The target process of the study is CO2 capture process by dry sorbent, which is exothermic or endothermic gas-solid systems consisting of a fast fluidized bed reactor and a bubbling fluidized bed reactor. When a reaction is highly endothermic, the heat of reaction should be supplied by heat sources.We used bench-scale dry sorbent CO2 capture process with 2 Nm3/h of gas treatment capacity. Experiments have been conducted to analyze heat transfer characteristics between steam-heated multiple horizontal tubes and solid sorbents of which average diameter is 100 micron in the bubbling fluidized bed reactor. The regeneration temperature was maintained around 150oC and controlled by supplied steam flow rate. The CO2 removal in the carbonator was maintained around 75%, which indicated that the regeneration energy was appropriately supplied by the in-bed type heat exchanging tubes with steam. |
