摘要

The present invention presents an integrated system for the production of Na₂HCO₃ from CO₂ captured from industries or power plants by means of a dry carbonate process starting from trona as raw material (Na₂CO₃ - NaHCO₃ - 2H₂O) and converting it into sodium carbonate (Na₂CO₃).;The optimized integration of the unit allows coupling the system with renewable energies at medium temperatures below 220ºC, such as biomass or medium temperature solar thermal energy systems. The use of this invention integrated in a CO₂ emitting plant results in a global system of almost zero CO₂ emissions, being able to meet the heat requirements of the global integrated system, minimizing the energy consumption of the CO₂ capture system and conversion to bicarbonate. This optimized integration reduces the energy and economic penalty of integrating the CO₂ capture system and conversion to value-added chemical.
