Baosteel Cuts SO2 Emissions by 50% in Four Years
02/16/2012 - According to its latest statistics, Baosteel Co., Ltd. has cut total SO2 emissions by over 50% since 2008. Its SO2 emissions in 2008 exceeded 30,000 tonnes, while in 2011 the emission was 15,000 tonnes.
According to its latest statistics, Baosteel Co., Ltd. has cut the total SO2 emissions by over 50% accumulatively since 2008. Its SO2 emissions in 2008 exceeded 30,000 tonnes, while in 2011 the emission is 15,000 tonnes. The company was recognized by the Shanghai Environmental Protection Bureau for its notable efforts in SO2 emission reduction.
Since installing a desulfurization device in No.2 generating set of Power Plant in 2004, Baosteel has successively carried out the construction of a desulfurization system for the sintering machine.
The desulfurization systems of the Stainless Steel Business Unit No.3 sintering machine and the Meishan Steel sintering machine are still under construction, but all the other generating sets and sintering machines within the scope of Baosteel have been completed and have maintained continuous operation.
To stabilize desulfurization efficiency, Baosteel promotes and makes improvements to the desulfurization operation procedure of generating sets, and strengthens the detection of process data of the desulfurization system, such as adding the detection analysis of slurry in the absorbing column for timely adjustment. Also helping was the exploration of the effective operation modes of dry desulfurization and wet desulfurization under different working conditions, and equipment defect elimination and process optimization.
Baosteel also encourages the production sites to keep improving the operating efficiency of desulfurization devices by strengthening the management and control. Thanks to the effects of various managerial measures such as SO2 total emission control, basic account management for operation of desulfurization device and online monitoring system of flue gas desulfurization, the operating efficiency and desulfurization efficiency of each set of desulfurization devices has steadily increased, the company claims.
The operation ratio and desulfurization efficiency of the generating sets of Power Plant reach 95% and 90%, respectively; the operation ratio and desulfurization efficiency of the sintering machine desulfurization devices in the directly affiliated plants and departments are also improved.
