Purification of sulfur paste to produce pure industrial-grade sulfur paste

Thread Content

Currently, the coal chemical, petrochemical, and fertilizer industries need desulfurization; the waste generated as a result of this process is sulfur paste. Since sulfur paste contains impurities and can pollute the environment, manufacturers are forced to pay others to remove it for disposal. Through scientific research and experimentation, we have achieved success in launching projects or starting production in Inner Mongolia, Xinjiang, and Yunnan. We are able to produce industrial-grade sulfur with a purity of 99.9%, at a cost of over 200 yuan per ton, while the current market price for this product is 1,300 yuan per ton. With 20 tons of sulfur paste processed per day, the annual revenue amounts to over 4.3 million yuan, which is a considerable profit; with subsidies added, the annual earnings can reach over 6 million yuan.
