On January 9, Hubei Sanning’s synthetic ammonia raw material structure adjustment and joint production of 600,000 tons/year ethylene glycol project (Phase I) ethylene glycol sewage plant #3 system continuously fed sludge for 12 hours, officially entering sludge domestication. stage, which marks that the device has initially acquired the ability to receive wastewater, and also laid an environmentally friendly foundation for the upcoming full-scale trial production.
It is understood that this set of equipment includes a 200m3/h circulating water backwash wastewater treatment system, a 300m3/h desalted water backwash wastewater treatment system, a 450m3/h comprehensive wastewater treatment system and a 10,000Nm3/ h odor treatment system. By the end of December, the conditions for mud acclimation are basically in place. Sludge acclimation in the comprehensive wastewater treatment system is a key step in the formal operation of the system and is directly related to whether wastewater can meet discharge standards.
At present, the circulating water backwash wastewater treatment system, desalted water backwash wastewater treatment system and odor treatment system have completed water intermodal transportation. It is expected that a set of system debugging will be completed before the year. By then, it will be based on the previous The drainage situation of the work section and debugging of the other two systems.
Hubei Sanning 600,000 tons/year ethylene glycol project
Hubei Sanning ammonia synthesis raw material structure adjustment and co-production of 600,000 tons/year ethylene glycol The project (Phase I) is based on the synthetic ammonia production capacity of Sanning Company’s urea plant and Tiantian Company’s 520,000 tons/year. On the premise that the production capacity will not increase, the existing atmospheric-pressure intermittent fixed-bed gas generators using anthracite as raw materials will be eliminated. Chemical furnace, atmospheric desulfurization, high-pressure ammonia synthesis urea plant and Tiantian Company’s ammonia synthesis unit and downstream urea and ammonium bicarbonate units. The estimated total investment of the project is 10 billion yuan. The new project will use Shenhua high-quality coal as raw material to produce 600,000 tons/year of ethylene glycol, 520,000 tons/year of synthetic ammonia, and 520,000 tons/year of urea; using sulfur as raw material, it will produce 800,000 tons/year. Industrial grade sulfuric acid.
Hubei Sanning Chemical Co., Ltd. is a coal chemical ethylene glycol project that fully implements the concept of circular economy development, selects energy-saving and environmentally friendly production routes, integrates advanced process technologies from many countries, and intelligent control systems and equipment. In order to achieve the purpose of green intelligent intrinsic safety. Hubei Sanning’s 600,000-ton coal-to-ethylene glycol project, which is nearing the end of construction, has automation and intelligence investment accounting for nearly 10%, far exceeding the proportion of all previous projects. As a life project for the transformation and upgrading of Sanning’s intelligent development, it adopts Lots of innovation.
Hubei Sanning Chemical Co., Ltd. was formerly known as Zhijiang County Fertilizer Factory and was founded in 1970. In 1993, it was transformed into a state-controlled joint-stock company as a pilot project. In 2001, it was reformed into a private enterprise through “two replacements”. In 2007, it became a controlling shareholder of Shanxi Jincheng Anthracite Mining Group Co., Ltd., a large state-owned enterprise.
