Abstract: Abstract:In order to reduce greenhouse gas emissions, carbon peak should be achieved by 2030 and carbon neutrality by 2060. A coal-fired unit coupled molten salt energy storage carbon capture system was proposed, in which the reheated steam was used to heat the low-temperature molten salt and provide energy for the regeneration of the MEA solution in the reboiler. The results show that the thermal efficiency of the coupled molten salt energy storage carbon capture system is increased by 4.14 percentage points compared with that of the traditional carbon capture unit, and the atmospheric CO2 emission is reduced by 82.34 t/h compared with the single coal-fired unit. The reduction of the output power of the energy release process unit is lower than that of the unit under the energy storage condition, and the output power of the energy storage process unit decreases by 34.99MW at the minimum, and the output power of the energy release process unit decreases by 6.68MW.
