摘要： A system and a process for capture and absorption of sulfur dioxide and carbon dioxide by an ammonia method at normal pressure are disclosed. The system has a dilute ammonia water supply device connected with sulfur dioxide and carbon dioxide absorption devices; an induced draft fan is connected with a heat exchanger connected with the sulfur dioxide absorption device; a sulfur dioxide absorption tower is connected with a carbon dioxide absorption tower; cooling devices in the sulfur dioxide and carbon dioxide absorption towers share a cooling water inlet and outlet pipe; the sulfur dioxide and carbon dioxide absorption devices respectively restore ammonia concentration to original ammonia water concentration by supplementing concentrated ammonia water; the sulfur dioxide and carbon dioxide absorption devices respectively pump solutions into the heat exchangers, then the solutions enter crystallization tanks; solid-liquid separation is performed through centrifuges, and the liquid continues to circulate in the system.
