1.The usage of ultrafiltration, nanofiltration, reverse osmosis technology for advanced treatment of titanium dioxide acidic waste water reaches the world leading level. It overcomes the blockage problem of impurities on the osmotic membrane, make the water consumption per unit of Titanium dioxide under 50t and sewage Unit Emissions under 20T.
2.The usage of imported high-titanium slag and ilmenite mixed raw materials that are difficult to be utilized reduces by 60% Waste residue discharge.
3.The achievement of industrialization of continuous acid hydrolysis technology makes titanium acid hydrolysis rate increase to 96% or more and increases the utilization rate of titanium resource to 87% or more from the 79% of the traditional process.
4.The 20% of the waste acid without concentration instead of 98% of the commercial acid for ammonium sulfate production is used firstly in the whole industry. Which Transforms waste into resources in energy-saving emission reduction methods and achieve Product Chain Coupling of Circular Economy.
Environment Protection:
Over the years, Zhengzhou SINO chemical Co.,Ltd conscientiously implement the national and all levels of government environmental laws and regulations, Regard the environmental protection as an important way for enterprise development and improve economic efficiency, adhere to the development of circular economy, comprehensive utilization of resources .
SINO circulating utilization the low-temperature heat recovery in the sulfuric acid production process , the annual recycling of steam 140,000 tons, 20,000 tons of coal, the steam value about 17 million yuan.
Using the original waste heat and pressure power generation projects, the annual power value of 13.68 million yuan, 2,950 tons of standard coal off ,400,000 tons of sulfuric acid project, supporting the waste heat power generation projects in generating 110 million KWh, two sets of basic networking to meet the Group after the production of electricity, the production process is no longer a ton of coal, the economic benefits significantly.
Water reuse project to achieve a "multi-purpose water, water use", water recycling rate will reach more than 90%. The introduction of advanced cooling system in Sweden, Switzerland advanced DRM washing device, combined with six sets of closed-circuit system and a water network can save water 400,000 tons / year.
4 sets low concentration of titanium dioxide acid water treatment system, processing capacity of 30,000 cubic meters dailly, to ensure that the outside drainage to a straight discharge standards.
Through a long-term efforts to significantly reduce the product consumption indicators, reduction of waste water 328,300 tons / year, the reduction rate of 9.9%, 113.75 tons of sulfur dioxide emissions / year, the reduction rate of 23%, COD 48.9 tons / Year, the reduction rate of 19%. Saving 950,500 tons per year, saving electricity 1080160KWh, 149,784 tons of steam section, product water, electricity, steam consumption unit, have reached the domestic advanced level.
Through our continuous efforts, the company efflux emissions, waste water quality is better than the national emission standards. Zhengzhou SINO has won the "national chemical environmental protection advanced enterprise", "Environmental protection work advanced Enterprise", "resource conservation advanced unit", "environment-friendly enterprise" honorary title. The company's existing "three wastes" emissions, titanium dioxide industry as the country will develop an important basis for one of the criteria.
Social Contribution:
With the continuous increase of our business scale, Sino Chemical now is one of leading enterprise in the titanium dioxide industry.In the passed years, Sino chemical has achieved great success, while we are always remember contributing to the Society. Charitable donations, disaster relief donations, golden autumn student aiding. Each penny of money, each piece of charity, takes the deep love of Sino people, also shows high social responsibility. We are honored as “Advanced taxpaying enterprises”which also contribute to our country fiscal revenue.
