Anhui Conch invests in wet desulphurisation pilot

Published by

Anhui Conch Cement Co. has invested CNY40 million in a wet desulferisation pilot project of kiln and end gas at subsidiary, Yangchun Chonch, in an effort to counteract the high sulfur content of the raw materials used at a number of its plants.

The pilot project produces limestone slurry out of the kiln dust generated in the cement production process. The limestone slurry is then added to the kiln exhaust gas, after the gas enters the absorption tower, combining with the SO2 to form a calcium sulphite.

When dried, this material can then be used as a cement admixture, replacing gypsum, within the cement production process. This provides an “economic value” to the process, the company said, in addition to the environmental benefits.

“The group intends to implement the improvement of wet desulfurisation at other plants in 2018,” the company said. According to the company’s annual sustainability report, it emitted 15 900 t of SO2 in 2017.
