On August 25th, reporters visited Qinghai Guoyuan Chemical Technology Co., Ltd. (hereinafter referred to as "Qinghai Guoyuan Chemical") located in Delingha Industrial Park, Haixi Mongol and Tibetan Autonomous Prefecture. Inside the workshop area, a 4-storey building stood out prominently, with workers welding pipelines on aerial work platforms inside the structure.

"This building is 29 meters tall, currently the highest one in the factory area. Inside, it houses the main body of the MVR high-salt wastewater treatment unit supporting the 30,000-ton/year potassium perchlorate project. It adopts secondary steam compression evaporation crystallization technology to achieve classified recovery of salts," introduced Si Xuepin, manager of the company's General Department. He added that by recycling substances such as potassium perchlorate and sodium chloride, this unit has built a full-scale treatment system for high-salt inorganic wastewater, which stands as a core highlight of the project's environmental protection technology.

Qinghai Guoyuan Chemical settled in Delingha in 2019. As a subsidiary of Continental Hope Group, the company leverages the salt lake resources in Haixi Prefecture and has deepened its focus on the salt lake chlorate industry chain in recent years. Its current product range includes sodium chlorate, potassium perchlorate, sodium perchlorate, etc.

Si Xuepin revealed, "The construction of the 30,000-ton/year potassium perchlorate project kicked off in April this year, and 80% of the project work has been completed so far. During the '15th Five-Year Plan' period, we will also build a 120,000-ton/year sodium chlorate project and a 60,000-ton/year liquid ammonia project."

Entering the main production workshop of the 30,000-ton/year potassium perchlorate project, a bustling scene unfolded. The roar of machinery mingled with flying welding sparks, as the project pressed ahead at full "accelerated pace". Zhu Wei, manager of the company's Production and Technology Department, led his team through the workshop, closely monitoring every construction detail and the project's overall progress.

On-site, core equipment such as high-potassium recrystallization tanks and centrifuges had already been hoisted into position. Some 6,000 to 7,000 meters of process pipelines were undergoing precision welding, with each weld joint subject to strict grinding to prevent blockages during material transportation. Zhu Wei noted, "As a strong oxidizer, potassium perchlorate is widely used in aerospace, fireworks, pharmaceuticals, and other fields. Its stability is superior to traditional potassium chlorate, making it a clear replacement trend in the industry."

Zhu Wei further introduced that a more notable achievement is the company's successful development of the "sodium chlorate - sodium perchlorate - potassium perchlorate" co-production process route for the 30,000-ton/year potassium perchlorate project. Guided by innovation, Qinghai Guoyuan Chemical drew on industry experience and combined it with its own practical conditions to create this route. This innovative breakthrough has not only injected strong momentum into the company's development but also opened up a new, efficient, and eco-friendly production path for the industry, setting a benchmark for scientific and technological innovation.

Additionally, during the project construction, the company significantly enhanced its work practices. It established a dedicated project team to implement standardized management, strictly adhered to timelines, and ensured the project advanced efficiently and orderly. Meanwhile, using regular safety meetings and high-frequency on-site special inspections as key measures, the company has built a full closed-loop mechanism of "inspection - rectification - review", integrating safety concepts deeply into all aspects of construction. Through concrete actions to improve work style, focus on project delivery, and promote implementation, it has firmly safeguarded the bottom line of safety.

It is understood that equipment installation for this project will be completed in mid-September, and the linked commissioning scheduled to start in October has attracted wide anticipation. With a proactive stance of gratitude, striving, and pursuing excellence through solid work, Qinghai Guoyuan Chemical is transforming this plateau-based green chemical project into a vivid practice of high-quality development, and making every effort to accelerate its progress in the chemical industry.
