FGD 3 times greater in China then in US

The McIlvaine research also shows that China is operating 379,000 MW of scrubbers compared to only 130,000 MW in the US. China has these FGD scrubbers on 67% of its coal-fired plants which is a higher percentage than in the US. China is also the largest supplier of many types of air pollution control equipment and several Chinese companies are the world's leading suppliers of electrostatic precipitators. According to McIlvaine, in recent years, suppliers of FGD systems have grown rapidly and ten of these companies are among the 20 largest FGD companies in the world.
