The new process generates no wastewater during the production process, achieving zero discharge of wastewater from the source of the process. All hydrogen sulfide waste gas is converted into sulfur for recycling, resulting in significant social, economic, and environmental benefits. In May 2009, this process passed the technological achievement appraisal in Henan Province and applied for two national patents.
Furthermore, the new process improves key production equipment such as high-pressure reactors and electric heating devices, reducing reaction time, increasing yield and product quality, and reducing raw material and energy consumption. The energy-saving and consumption-reducing effects are also remarkable.
