Balucan, R. D. & Dlugogorski, B. Mervine, E. M., Humphris, S. E., Sims, K. W. W., Kelemen, P. B. (PDF) Precipitation of magnesium carbonate - ResearchGate We have assumed that electricity will be generated off site, and that the emissions from generation are not captured. Sci. From the energy analysis on each unit operation, operating costs for the system were developed. For two reasons. The number of carbonation plots was determined to meet this operational capacity. Phys. The resulting MgO can be exposed to weathering again, and so on. Acta 68, 3145 (2004). Environ. Additionally, it was assumed that 9095% of the MgO will be recollected as MgCO3 or unreacted MgO, while 510% of this material will be lost to the environment. Eng. - 18239938 Finally, or in parallel, Mg-silicates from ultramafic rocksolivine-rich peridotite from the Earths mantle and its hydrated equivalent, serpentinitecould be used as a source of MgO. Zevenhoven, R., Teir, S. & Eloneva, S. Heat optimisation of a staged gassolid mineral carbonation process for long-term CO2 storage. Geochim. Int. Rev. Here, the material is fed to the calciner with additional magnesite feedstock to make up for environmental losses from the previous cycle. The costs of building and operating such reactors contribute significantly to integrated looping cost. Energ. Finally, capital expenditures for the process were annualized using capital recovery factors of 7.4% for the lower bound and 12.6% for the upper bound. For simplicity, peridotite can be simplified as nearly pure Mg-olivine (Mg2SiO4), and serpentinite as serpentine (Mg3Si2O5(OH)4) and brucite (Mg(OH)2). Fajardy, M., Chiquier, S. & Dowell, N.

Ultimately, the produced cost of CO2 is equivalent to the price at which CO2 could be sold for the process to break-even. Tribe, M. A. The produced MgO is then transported to land plots where it is deposited and allowed to carbonate over a year. With each energy source, there are associated CO2 emissions.
