Over the past two years, the chlor-alkali industry in Henan province has risen at an alarming rate. There have been large-scale calcium carbide-based PVC manufacturing companies such as Yuhua Yuhang Chemicals Co., Ltd., Henan Shenma Chlor-Alkali Development Co., Ltd. and Henan Hengtong Group. Henan became one of the important chlor-alkali production bases in China.
Not only along the river and not along the coast, there is no market and logistics advantages, there is no coal power resources, Henan Province, an agricultural inland provinces, how can chlor-alkali into a fist industry? The reporter investigated with doubt.
Thanks to "No East West"
The polyvinyl chloride production process mainly includes ethylene oxychlorination using petroleum as a basic raw material and acetylene using calcium carbide as a basic raw material. China's chlor-alkali industry is mainly distributed in eastern and western China. The strength of the east is the ethylene method, and the strength of the west is the calcium carbide method. However, these two major strengths of the East and West have encountered challenges in recent years.
In the east, since 2003, the international crude oil price has been operating at a high level. By this year, the price of crude oil has exceeded 100 US dollars/barrel, resulting in a substantial increase in the cost of ethylene-based polyvinyl chloride (PVC). This has led to an increase in the cost of ethylene-based PVC in the eastern region and long-term losses. .
Western, Xinjiang, Ningxia, Inner Mongolia, and other provinces and regions rely on energy, resources, and other advantages, are good at calcium carbide polyvinyl chloride, chlor-alkali industry has developed rapidly. However, an unavoidable fact is that due to the small consumption in the local liquid caustic soda market, sales have been seriously affected, and its PVC products are further away from consumer markets such as East China and South China. Therefore, one end is that caustic soda, liquid chlorine and other products are weak in local digestion capacity, and the other is the restriction of long-distance transport of polyvinyl chloride. The weakness of these two headaches will compromise the development advantages that chloro-alkali enterprises in the western region originally had.
The advantages of the eastern and western regions have all been discounted. The advantages of Henan Province in the Central Plains, such as cost, resources and labor, have been highlighted. It was at this time that the chlor-alkali enterprises in Henan Province narrowed their eyes and took advantage of this golden opportunity for development.
Former Yuhang Aerospace, which was “just a small chemical plant†in the eyes of people, started to produce caustic soda and polyvinyl chloride in 2002. It is almost a year-long step, and it has become a domestic large-scale calcium carbide process polyvinyl chloride for several years. Production enterprises, caustic soda and polyvinyl chloride reach a scale of 400,000 tons at the same time, and they have a considerable scale of competitiveness in domestic counterparts.
After more than 30 years of development, Shenma Chlor-alkali Company had a capacity of caustic soda and PVC of only 80,000 tons/year by 2003. However, it is precisely because of the rare historical opportunity that has been seized. After two large-scale expansions in 2005 and 2006, Shenma Chlor-Alkali's annual production capacity of caustic soda and PVC has reached a scale of 200,000 tons. Chlor-alkali in the company's big chain of the industry chain from the "little brother" transformed into a large profit tax, sales in 2007 increased by 164% year on year, profit growth of 883%. By the second half of this year, the company's annual production capacity of caustic soda and polyvinyl chloride will reach 400,000 tons.
Henan Hengtong Group is the first PVC manufacturer in Henan Province. After restructuring in 2003, it has implemented an annual expansion of 60,000 tons, 120,000 tons, and 300,000 tons of expansion projects in just over four years, making the company PVC. The scale of production has soared. By August this year, the group will have an annual production capacity of 400,000 tons of PVC.
As of 2007, caustic soda and polyvinyl chloride in Henan reached a million-ton level, making it one of the largest and most important chlor-alkali production bases in China.
Benefit from the downstream market
The main reason why the chlor-alkali industry in Henan can grow up quickly is the market. The chlor-alkali industry in Henan Province can grow rapidly. The biggest advantage is the cornucopia-like market.
Caustic soda is mainly based on aluminum processing, chemical fiber, papermaking and protopine processing industries. After entering the 21st century, the Henan provincial government has developed the aluminum processing industry as a pillar industry, which provides a huge marketing market for chlor-alkali enterprises in Henan. It can be said that the formation of industrial clusters of Henan aluminum processing industry has created a cluster of chlor-alkali industry.
The market share of alumina and electrolytic aluminum in Henan Province has been the first in the country for many years. China National Aluminum Corporation's Zhongzhou Branch and the Henan Branch have alumina production capacity ranking first and third in the country respectively. Zhengzhou, Luoyang, Sanmenxia and Jiaozuo regions have concentrated more than 90% of alumina production capacity and 70% of electrolytic aluminum production capacity in the province, forming the largest aluminum industrial cluster in China. And its technical level is also in a leading position in the country. During the "11th Five-Year Plan" period, Henan Province will continue to vigorously develop the coal, electricity and aluminum processing industry chain and vigorously cultivate aluminum industrial bases with international competitiveness. This excellent market has provided unique conditions for the development of Henan chlor-alkali chemical industry.
Geographical advantages have also extended Henan's chlor-alkali industry beyond the province. China's PVC consumer market is mainly concentrated in East China and South China, accounting for about 70% of China's total consumption capacity. Henan is located in the hinterland of China's Central Plains, east to west, north to south, and this location advantage and transportation logistics advantages have all been transformed into market advantages by its chlor-alkali enterprises, making Henan PVC easily accessible to East and South China. market.
Henan Hengtong Group has more than 50 fixed customers, mainly distributed in Guangdong, Zhejiang, and Jiangsu. Each customer uses about 3,000 tons of polyvinyl chloride per month, and the annual demand of customers is more than 500,000 tons. Since the establishment of the company, all sales of PVC have been pre-paid and shipped, achieving zero inventory. Yuhua Aerospace's PVC products cover almost all PVC products in East China, South China, and in and around the province. At the same time, in order to circumvent the highly competitive domestic chlor-alkali market, Yuhuan Aerospace also participates in the international market competition. Since 2005, it has started its international operations and achieved 5,000 tons of PVC exports. In 2006, Shanghai Haoyu Company was established and an international trade platform was established. The business structure of “Industry and Trade Integration†was formed and the products were sold to 13 countries and regions.
Benefit from circular economy
The chlor-alkali industry is a typical high-energy, high-pollution and resource-based industry. However, the development of chlor-alkali enterprises in Henan in recent years has shown a new look to chlor-alkali experts and colleagues both at home and abroad, and wiped out the impression of “energy guzzlers†remaining in people's minds.
Most chlor-alkali enterprises in Henan Province use the world's most advanced ion-membrane electrolysis process, tower stripping and de-elution of vinyl chloride technology, 70-cubic-meter polymer autoclave isothermally closed feed technology, DCS automation control technology, etc. Leading position in the industry. High-tech means low cost, and Henan chlor-alkali companies have proved this.
In the interview, the reporter saw that the heads of Henan chlor-alkali enterprises are deliberately doing a good job of circular economy. As Xu Haohong, Chairman of Yuhua Aerospace, said: “The circular economy is a compulsory course for the chlor-alkali enterprises to do energy-saving and emission reduction work, and it is the only way for chlor-alkali enterprises to reduce costs and increase their core competitiveness.†These companies exert their efforts and create chlor-alkali. There are many “most of the best†in energy saving and emission reduction in the industry.
Hao Hua Aerospace has achieved many miracles in energy saving and emission reduction that are difficult to believe for its national counterparts: The national standard for environmental protection boiler smoke and dust indicators is below 800 mg/m3, and Suihua Aerospace is actually below 100 mg/m3; the national standard for sulfur dioxide is Below 1200 mg/m3, Suihua Aerospace is actually 200 mg/m3 or less; the national regulations stipulate that the quality of polyvinyl chloride is less than 20 for fisheyes, and Yuhuan Aerospace should be controlled below 10, and be implemented as an enterprise standard; vinyl chloride Residual national standards are 8 micrograms/gram, and Sinochem Aerospace controls below 5 micrograms/gram.
Henan Hengtong Group is unique in its operation mechanism, making full use of the complementary advantages of the related companies in the industrial cluster area of ​​Kongshan, and developing circular economy to protect the ecological environment. For example, the waste heat boiler is built, and the production waste heat of the local cement company is used as the heat source for the production of the enterprise. At the same time, the calcium carbide slag of the industrial waste is pressure-filtered, dried, and then directly delivered to the cement company for cement production. Every year, 500,000 tons of calcium carbide slag is eaten on the spot, forming a circular economy industrial chain that is reduced, reused, and resourced. They used a pressure swing adsorption device to recover monomer and acetylene, established a comprehensive exhaust gas utilization network, increased the use efficiency of calcium carbide by 20% compared with traditional chlor-alkali enterprises, and reduced the consumption of calcium carbide to 1.4 tons, which is the lowest in the domestic industry. .
Shenma Chlor-alkali Company has the most innovation in consumption management over the past few years: The indicators for the best months of the previous year have been used as the worst indicator of the year so that the indicators have steadily declined year-on-year. Its 200,000 tons/year caustic soda and polyvinyl chloride project not only takes into account the comprehensive utilization of waste slag, but also complements many projects such as energy, fine chemicals, deep processing of products, etc., creating “energy use, energy consumption, circulation Increase economic efficiency."
The development trend of the chlor-alkali industry in Henan Province in the coming years will remain strong. Shenma Chlor-alkali Co., Ltd. said that in 3 to 5 years, it will reach an annual output of 1.2 million tons of caustic soda (100%) and 1.2 million tons of PVC production capacity, becoming a world-class chlor-alkali chemical base. Yuhua Aerospace will also use 2 to 3 years to make caustic soda and polyvinyl chloride form a million tons, and the sales revenue will reach 10 billion yuan.
Not only along the river and not along the coast, there is no market and logistics advantages, there is no coal power resources, Henan Province, an agricultural inland provinces, how can chlor-alkali into a fist industry? The reporter investigated with doubt.
