DEVELOPED BASED ON MATURE & PROVEN TECHNOLOGY The gasifier reactor and burners used in the Bottom Quench technology are virtually the same as those used in SCGP. The syngas cooler, for heat recovery, has been replaced by a dipleg water quench bath. Key design features: multi-burner, membrane wall, bottom water quench. Bottom Quench Membrane wall Opposed multiple burner Dry feed system Flyash removal system Compared with SCGP SGC Same Same Same Proven at a commercial scale in Nanjing syngas plant 8
