تاثیر فشار مویرگی بر تعادل فازی در سیستم CO2 در آب: استفاده برای جداسازی کربن در ترکیب با انرژی زمین گرمایی

For mixed CO2–water injection into a geothermal reservoir, the influence of capillary pressure on the phase equilibrium reduces both the heat recovery up to 37% and the CO2-storage capacity up to 37%. We construct a plot of the recuperated heat energy versus the maximally stored CO2 for a variety of conditions; we compare the results including and excluding the effect of capillary pressure in the phase-equilibrium calculations. We also provide a cursory evaluation of the energy and economics of mixed CO2–water injection into a geothermal reservoir.
