摘要：

This paper introduces the model of flue gas desulfurization by small size coal-based sorbent and results of fundamental support test studies. The SO2-removing efficiencies of more than 90% are achieved during multi-cycle tests in the downward entrained bed reactor. Sorbent regeneration by indirectly heating leads to tail gas consisting of 40-50% of SO2. The tail gas after cleanup is pressurized up to 2.0-3.0 MPa and cooled down to 0-20 degrees C resulting in gain of liquid sulfur dioxide at rate of 80-94%.
