Domestic application record of anodic protection shell-type acid coolers with a capacity of over 600 m2
Thread Content
Please provide information on the usage records of anodic protection shell-type acid coolers with a capacity of 600 m2 or more in China; it would be ideal if such units have been in use for over 5 years without any leaks. It is recommended that the performance format be as follows: 1. Anode protection area (m2) ； 2. Acid volume (m3/h), inlet and outlet temperatures on the acid side ； 3. Type of heat exchange tubes, such as domestic seamless tubes, imported seamless tubes, imported welded tubes, and domestically welded tubes made from imported sheets ； 4. Operating conditions, fault-free operation time, and whether there have been any acid leakage incidents ； 5. If there has been a leak, please indicate the cause ； 6. Manufacturers, etc ； 7. Others.

Tianhua Institute has a large number of equipment units with a size of over 600 m2, and the maximum heat exchange area is 1630 m2. The maximum diameter is 1800 mm. Tianhua Institute undertook the scientific research and development project for the development of concentrated sulfuric acid coolers for anode protection in large-scale sulfuric acid plants, as assigned by the Ministry of Science and Technology. A lot of foundational work was done. The Huuludao Zinc Plant, Jinchuan Company, Guixi Smelting Plant, Yanggu Xiangguang, Daye in Hubei, Baiyin Company, Yunnan Copper Industry, and Tongguan Metallurgy all have the equipment you mentioned ； Sinochem Kailin, Yunnan Furi, and Sanhuan also have them ； There are also ones abroad in the Chambeshi and Turkey (general contractor: Tianchenyuan). For large-scale equipment, it is essential to prevent fluid-induced vibrations from causing damage to the acid coolers ； It is necessary to conduct flow velocity analysis at all special locations within the equipment ； Special position stress analysis must be conducted. Large projects mostly use welded pipes imported directly from the United States. Tianhua Institute has developed a shunt-type shell-side acid cooler tailored to the actual characteristics of large-scale plant processes, which can help owners save approximately 25% on investment costs.

Which of the aforementioned devices has the longest fault-free operating time, and what is its manufacturer and location of installation?
I have been working on the design of large-scale anodic protection concentrated sulfuric acid coolers for many years. From my experience, if the owner and the design and manufacturing parties communicate thoroughly and ensure a proper profit margin, the design and manufacture of large-scale anodic protection concentrated sulfuric acid coolers can be carried out with complete confidence. Large projects require bidding processes. If thorough discussions can take place prior to the bidding, and based on those discussions and common understandings, the project owner or industry experts can establish a base price, this is highly beneficial for selecting equipment with a reasonable cost-performance ratio. In recent years, there have been many large-scale sulfuric acid plants, and the involvement of design institutes or project consulting firms is very beneficial for selecting equipment with a favorable cost-performance ratio. Many projects actually have tripartite contracts signed. Technology is the responsibility of the owner and the design firm, while business matters are the responsibility of the owner.
The acid cooler of Sinochem Kailin’s 600,000-ton plant has been replaced. It was replaced in 2006, I think.
No manufacturer dares to claim that their acid coolers have never leaked. In China, Tianhua and Lanzhou Xingye are the better ones. You can consult them.
The leakage in Sinochem Kailin’s 600,000-ton acid cooler has nothing to do with its design or manufacturing. You can contact the owner. I once again hope that you will not include specific factory names. It’s best to understand the issue clearly before expressing your opinion. Even though it’s the internet, it’s still necessary to seek truth from facts.
