China's titanium dioxide industry has entered the era of green manufacturing and rapid sustainable development

Titanium Dioxide Enterprise's Third-Quarter Growth Slowdown industry in China has experienced 60 years of development. During the “Thirteenth Five-Year Plan” period, the titanium dioxide industry has also entered a critical period of “transformation and upgrading”. At present, China's titanium dioxide industry still does not get rid of the extensive mode of high investment, high consumption, and high emissions. In order to achieve the energy saving, green, and sustainable development of the Chinese titanium dioxide industry, titanium dioxide enterprises must strengthen technological innovation, focus on scientific development and the body. Environmental construction.

To deal with environmental pollution, it is necessary for the government, society and the market to work together

In recent years, the State Council has successively issued the “13th Five-Year Plan” Pigment And Dye for the development of ecological environmental protection and the action plan for the prevention and control of atmospheric, water, and soil pollution, referred to as the “Three Ten,” with concrete data to define environmental protection goals. The State Council also proposed different ideas for the three goals. On August 29, 2016, the "People's Republic of China Environmental Protection Tax Law (Draft)" was first submitted to the Standing Committee of the National People's Congress for consideration. The draft changed the current "sewage charges" to "environmental protection taxes."

Mr. Yang Chaofei, the president of the China Industrial Environmental Promotion Association and former chief engineer of the Ministry of Environmental Protection, pointed out that the treatment of environmental pollution depends on the government, society, and the market. In his opinion, to change the notion of relying entirely on the government, “the Boric Acid Flakes government can no longer perform paternalistic and nanny-type supervision over enterprises. It is necessary to implement the responsibility of local governments for environmental quality, to substantially increase the cost of illegal pollutant discharge, and to use the market to allocate resources. It has a decisive role, establishes a working mechanism for polluting enterprises to achieve compliance, improves the environmental protection and social governance system, and relies on scientific and technological progress to solve pollution problems."

Titanium Dioxide Anatase is a production-type product. The three wastes produced in production—exhaust gas, waste liquid, and waste solids—are also among the emission taxes. The emission tax Melamine Powder of solid red gypsum from the sulfuric acid method is up to 25 yuan/ton. In the face of emissions taxes, Taiwanese companies must adopt innovative production models to achieve technological reductions and even reduce emissions.

Industrial Environmental Protection Policy Promotes Titanium Dioxide Industry Transformation and Upgrading

In 2016, the Central Environmental Protection Inspectorate stationed in various provinces and conducted special inspections on outstanding issues in the field of environmental protection. The company mainly inspected the production of enterprises, implementation of environmental protection, environmental protection issues of enterprises, toxic and hazardous pollutants, and discharge of hazardous wastes and air pollutants. In strict environmental supervision, the “Half-hour Economy” section of CCTV has exposed the environmental pollution problem in Panzhihua City. Panzhihua City subsequently imposed a cut-off on 36 companies. After careful investigation, the real culprit of water pollution from CCTV was mainly caused by the leakage of some mineral processing companies, including 16 companies in the Vanadium and Titanium High-tech Zone.

On December 20, 2016, Panzhihua City, Sichuan Province organized a symposium on the production and management of titanium dioxide and environmental protection. Although the pollution was not caused by the titanium dioxide company in the high-tech zone, the titanium dioxide companies in the forum jointly issued a joint commitment letter on environmental protection and took the initiative to make solemn promises to the environmental protection departments at all levels and the general public to firmly establish environmental awareness and strictness. We must abide by environmental laws and regulations, strengthen pollution prevention and control, and consciously accept social supervision, further strengthen self-discipline, regard environmental protection as the life of a company, and act as an honest and law-abiding business. Titanium dioxide enterprises are deployed according to their superiors, and they stop production, inspect, rectify, renovate, and formulate measures such as clean production, sewerage and stacking.

Dr. Li Xiaoliang of the Environmental Planning Institute of the Ministry of Environmental Protection of the People's Republic of China put forward several suggestions for titanium dioxide enterprises for the implementation of industrial environmental protection policies: First of all, we must pay attention to the discharge standards, especially the key limits; attach importance to innovation, focus on active promotion, open information, and take the initiative to participate. Relevant environmental policies are formulated and strived to be integrated into the scope of implementation of the environmental protection leader system. Relying on policies, self-discipline in the industry will be strengthened to promote the transformation and upgrading of the titanium dioxide industry. (In 2016, the Ministry of Industry and Information Technology selected “leaders” in the energy efficiency of ethylene, synthetic ammonia, cement, plate glass, and electrolytic aluminum industries, selected 16 “leaders” enterprises that have reached the leading level of energy efficiency in the industry, and reached advanced energy consumption limit national standards. The value of the finalists is 20.

Energy Saving Green Manufacturing Promotes Technological Innovation

Titanium Dioxide Clean Production, Strengthen Energy Management

After the innovation and technological transformation of the titanium dioxide production line, to achieve a joint production of sulfur iron and titanium, sulfur phosphorus and titanium and other co-production cleaner production process. In the establishment of a sound energy management system, through the strengthening of energy management, can reduce production energy consumption by 7% -20%. Titanium Dioxide Green Manufacturing and Energy Saving Production.

Titanium Dioxide Waste Treatment

Wastewater: The water consumption of titanium dioxide is greatly reduced. The vast majority of titanium dioxide in China is produced by the sulfuric acid process, and the production capacity of the chlorination process is less than 10%. Sulfuric acid method titanium dioxide is a large water-consuming household, and the early small-scale titanium dioxide plant had a water consumption of 200 M3. With the development of science and technology, advances in equipment, and technological innovation, water consumption has dropped dramatically. The production of titanium dioxide generally goes through three steps of washing, three washings can be washed with two, two washings with one washing, and the washed acid can be purified and concentrated for recycling. At present, the energy consumption per ton product of domestic sulfuric acid method titanium dioxide has fallen to below 100M3, and some plants have even dropped below 50M3.

Waste Acid: Sulfuric acid also becomes an impurity after the impurity removal task is completed in the production of titanium dioxide. It can recover 15-20% as a whole by using the acid and the initiator solution. A large amount of waste acid also needs to be processed. The current treatment method is to increase the utilization rate through the recycling economy industrial chain, produce iron sulfate-containing water purifiers for sale, or enter the sewage treatment for neutralization, and the waste gypsum is used in cement plants or landfills.

Waste solid: As a waste solid ferrous sulfate and gypsum, you can go through in-depth development, production of iron pigments, production of architectural gypsum and other products. Increased waste solids utilization.

Titanium Dioxide Enterprise Self-discipline, Practice Green Sustainable Development

The first China Titanium Dioxide Industry Energy Saving Green Manufacturing and Application Forum was organized by the China Titanium Coatings Association of China Paint Industry Co., Ltd. and was co-organized by the Shandong Daun Titanium Industry Co., Ltd., a subsidiary of the Daun Group. It was held in Longkou, Shandong Province on June 28. As the main co-organizer of the forum, Mr. Yu Xiaoning, chairman of the Daun Group, called on everyone to actively implement green sustainable development in accordance with the six requirements of green development of the China Petroleum and Chemical Industry Federation in strict accordance with environmental protection requirements. Titanium dioxide counterparts are urged to strengthen management, improve processes, strengthen environmental protection, and control costs.

Yu Zong also introduced Dawn’s advanced experience: Dawn Titanium Company has now reached a production scale of 130,000 tons of rutile titanium dioxide, using international and domestic advanced sulfuric acid process rutile titanium dioxide production process, the entire line to achieve clean production And integrated operations (ie, through the industry to achieve waste utilization and energy recycling). The company has made remarkable achievements in clean production, energy saving, titanium dioxide production process innovation, waste water, waste gas, waste residue treatment, and comprehensive utilization of waste by-products. It is a clean production and recycling economy focused on China's titanium dioxide industry technology innovation strategic alliance. One of the demonstration projects has been awarded by the China Petroleum and Chemical Industry Federation for three consecutive years as the "energy efficiency leader in benchmarking." Dawn Titanium, as a benchmarking company for energy efficiency leader, through the concept of green development, the introduction of advanced technology at home and abroad, in the use of wastewater, waste gas, waste residue has a certain amount of harvest, a qualitative leap.

Mr. Sun Peng, Chairman of the Titanium Dioxide Branch of China National Coatings Industry Association also pointed out that the discharge and emission reduction of titanium dioxide industry in China has become the top priority for titanium dioxide production. Titanium dioxide industry should strengthen technological innovation and pay attention to the development of ecological health. To achieve the sustainable development of the Chinese titanium dioxide industry and work hard!

At present, China's titanium dioxide manufacturing industry is in the middle and low end of the industrial chain. In 2016, the nation’s production of 2.7 million tons of titanium dioxide powder ranked first in the world, but China’s high-end titanium dioxide products still rely on imports. As a resource-consuming product, the self-sufficiency of raw materials for titanium dioxide in China is insufficient, which also restricts the rapid development of the titanium dioxide industry. Titanium dioxide must fully promote green manufacturing, accelerate technological transformation, and develop in the direction of high technological content, low resource consumption, and low pollution, and realize the green and healthy sustainable development of the titanium dioxide industry.
