Ningbo Taiji Environmental Protection Equipment Co Ltd FGD technology was officially put into operation successfully being used in 230 square meters sintering.

For the project, TAIJI chose to use steel slag as an absorbent instead of lime or other absorbents traditionally used in desulfurization. In comparison to the use of lime agents, the replacement reduces SO2 emissions by more than 6600 tonnes and carbon CO2 by more than 4600 tonnes equivalent to savings of CNY 3 million and 8000 tonnes of lime desulfurization agents.

TAIJI core offerings center on the breakdown of industrial solid waste pollutants. Using a desulfurization multi phase reactor, steel, nonferrous metallurgy, thermal power, residue from chemical and other industries, fly ash, zinc oxide, carbide, white clay, red mud and other absorbents of sulfur dioxide solid waste are employed to create a more efficient desulfurization process, as well as to transform desulfurization by products into alkaline sand.

According to statistics, China produced more than 600 million tonnes of steel in 2009, resulting in 100 million tonnes of steel slag emissions and 24 million tons of SO2 emissions. Approximately 90% of current desulphurization technology uses limestone or lime gypsum to absorb SO2. For every 10 million tons of SO2 that are absorbed, 30 millions of steel slag are used, reducing CO2 emissions by seven million tons, reducing the use of lime by 12 million tons, and saving desulfurization businesses CNY 4.2 billion in production costs. At the same time, the waste residue that is produced can be used to modify 80,000 hectares of saline alkaline land.
