1. A method of heat recovery in a carbon dioxide (CO2) capture and separation system, the method comprising:
introducing steam generated by an evaporator 101 into a reactor 102 of the separation system;
heating a sorbent material 103 in the reactor 102 using the steam, wherein the steam leaves condensed water, steam vapor, and CO2 within the reactor 102;
in response to a temperature reaching a first predetermined threshold and pressure within the reactor 102 reaching a second predetermined threshold, opening an outlet valve 202 downstream from the reactor 102;
directing, via the outlet valve 202, a product stream comprising the steam vapor and the CO2 from the reactor 102 to vapor re-compressor 111;
cooling and condensing the directed product stream from the vapor re-compressor 111 in a condenser 105; and
recovering latent heat from the product stream with the condenser 105 by directing a first portion of the vapor from the condenser 105 to the evaporator 101.
