Who is the best PVC manufacturer in the country?
Thread Content
The PVC industry has seen significant development over the past few years. I wonder which company in China is the best in terms of PVC production (technology and efficiency). Please share your opinions.
The technology used by the Ningxia Qingtongxia Resin Factory was introduced from Shanghai Tianyuan Chemical Plant, and it has been further improved through adaptation; the power consumption per ton of alkali produced in this diaphragm cell process is around 2,350 kWh
There is no best, only better; different perspectives lead to different opinions.
Benefits: 4 x 70m3 reactors per system = 125,000 t/year
4 reactors with a capacity of 70 cubic meters each, resulting in a total capacity of 125,000 tons. Where are you from? Please share your experience. What kind of cooling water do you use?
It’s hard to say; there are advantages and disadvantages in terms of technology. The benefits also vary depending on the scale.
Actually, you shouldn’t ask questions like that; everyone has strengths and weaknesses. Without a place to stand, one loses the value of existing.
Then let me ask casually, which one offers better benefits to employees?
This output is quite high; generally, 2.5 WT per unit per year is already considered good. Where is it produced, and what are the secrets behind it?
Technically speaking, Beierhua’s PVC process is excellent; Shanghai Chlor-Alkali excels in caustic soda production and control. In terms of efficiency, Western Chemical and Tianye are the best. Last edited by shizhiyong001 on 2009-2-6 08:22.]
3wt per unit is also quite easy to achieve. The temperature here is relatively high, so the polymerization system uses chilled water throughout; electricity costs need to be low. Although all the materials used are of top quality, the molecular chain distribution is uneven
In 2007, there were 5 companies in China that produced PVC products recognized as national brand products (using the suspension process): Qilu Petrochemical, Tianjin Dagu, Shanghai Chlor-Alkali, Yibin Tianyuan, and Xinjiang Tianye. Among them, Tianjin Dagu, Yibin Tianyuan, and Xinjiang Tianye achieved the best results. Each of these companies has its own advantages in terms of technology; currently, the technologies that are widely used in China are those developed by Beierhua and Tianjin Dagu.
Cangzhou Cangjing Chemical should be missing from the list above; this company currently has a production capacity of 230,000 tons per year, and its technology comes from Japan’s Mitsubishi. It was acquired by Xingtai Jinniu Energy this year, and production is expected to reach 700,000 tons per year next year.
When it comes to economies of scale and brand, Tianjin Daguhua is certainly a good choice. Production in 2007 was close to 700,000 tons.
Cangzhou Cangjing Chemical is a joint venture between Canghua and the Japanese company Mitsui; I remember that one year, Canghua’s production volume and scale were the highest in the country. However, due to the rise in the price of dichloroethane, Sōi went bankrupt. The polymerization and post-treatment technologies of Soi, as well as those of Tianjin Dagu Chemical, all originate from Japan’s Chisso Corporation. In 2007, Tianjin Dagu’s PVC production reached 700,000 tons, and it developed its own post-treatment system with a capacity of 200,000 tons per line, while Cangjing went bankrupt. Sweat! ! !
:victory: :victory: :victory:
Who has the contact information for Beierhua?
Why is the quality control of Yili’s PVC not good? Impurities keep appearing; how should this be controlled?
In terms of scale and technology, I believe Tianjin Dagu Chemical Plant is the best; its designed production capacity reaches 840,000 tons, and it has polymerization reactors of various sizes, including 30, 60, and 108 ton capacities. It has also done an excellent job in introducing and integrating new technologies. The level of efficiency is related to various factors such as the size of the enterprise, the allocation of resources, its location, and the product structure. Taken all together, I believe that Yibin Tianyuan and Xinjiang Tianye are performing well.
Technical and economic indicators are comprehensive metrics, so it’s hard to say. Once we get through this cold winter, everyone will know for sure! This post was last edited by tfx511024 on 2009-1-2 at 12:25.]
Different people have different views; there is no perfect solution, only better ones.
