Precipitation Control of Calcium Carbonate Crystal Polymorph as Sequestration of CO2 Chemical Absorption in Amine |
| 초록 |
Technology existed for gas sweetening process is chemical absorption of CO2 using amine. Included in this process is regeneration of amine by heat. Regeneration process increase 70-100% cost of electricity mainly because of its heating duty. By this mean, mineralization as alternative to utilize and store the CO2 after absorption is proposed. Mineralization converts CO2 into stable mineral such as calcium carbonate, this process can be done through chemical precipitation. However, precipitation must be controlled to produce calcium carbonate with high yield. In this work; feed rate, calcium source, mixing rate, and temperature are varied to get the optimum parameter of precipitation. Crystal morphology is investigated as effect of each parameter used. |
