Single-absorption 对一转一吸制酸装置
– Reduce SO2 emissions by up to 40% with VK-701 LEAP5TM in the final pass 最后一段装填VK-701 LEAP5TM可减排二氧化硫高达40%
Double-absorption 对两转两吸制酸装置
– Cut SO2 emissions by 40% in 3+1 plants operating with VK69 by replacing the 3rd pass with VK-701 LEAP5TM 对于已装填VK69的3+1制酸装置，将第三段改为装填VK-701 LEAP5TM ，可 减排二氧化硫高达40% – Achieve 50 ppm SO2 emission from existing 3+1 plants 用于现有3+1制酸装置改造，可以实现50ppm的二氧化硫排放浓度 – Design new plants with 20-50 ppm SO2 用于新建装置，SO2排放浓度可低至20-50 ppm – Avoid tail-gas scrubbing 无需尾气洗涤装置
