Treatment background of desulfuration and decyanation liquid waste

(1). Domestic present status: at present, the annual output of coke is 480 million tons, desulfuration waste liquid is 5 million tons. About 40% coke enterprises have applied desulfuration waste liquid treatment devices, and most of the other enterprises adopt waste liquid coal blending or emission. At present, the comparatively mature coking desulfuration and decyanation waste gas treatment technology is HPF method taking ammonia as absorbing medium, A.D.A. method taking sodium carbonate as absorbing medium, vacuum potassium carbonate method taking potassium carbonate as absorbing medium. 

(2). Liaoyuan mainly engages in coking desulfuration decyanation waste water treatment and thiocyanate production. The company firstly establishes all industrial chain system including waste liquid treatment, R&D, production, and sales in the industry, and it has domestic advanced coking gas desulfuration and decyanation waste water treatment technology with proprietary intellectual property rights. Liaoyuan is a national key high-tech enterprise and private science and technology enterprise of Jiangsu.
As the most influential manufacturer and exporter of thiocyanate products in China, the company has updated the coking gas desulfuration and decyanation waste water treatment technology. In 2011, the company added 60,000T salt extracting from coking gas desulfuration and decyanation waste solution in Shagang Group.

(3). Liaoyuan technology is suitable for the treatment of desulfuration and decyanation solutions produced from HPF method taking ammonia as absorbing medium, A.D.A. method taking sodium carbonate as absorbing medium, vacuum potassium carbonate method taking potassium carbonate as absorbing medium.
