​"I am currently working on the process design of a natural gas CO2removal unit using activated MDEA (aMDEA) solution. The design parameters are: gas flow rate of 77 MMSCFD, inlet CO2 concentration of 15%, and outlet CO2 concentration of ppm}. Preliminary calculations show that the amine regenerator reboiler duty is 26 MW, heated by hot oil. With such a massive heat load, a single kettle reboiler would result in an extremely large equipment size, which is causing me a major headache. Does anyone have suggestions on how to optimize this reboiler configuration
