With the rapid development of China's economy, the demand for chemical products has increased rapidly. Many domestic acetic acid industry projects using zirconium tubes have been launched in batches. Feasibility research and research projects on the use of zirconium materials in more chemical production processes are also The rapid development has led to a rapid increase in the domestic demand for zirconium tube materials. Due to the limited production capacity of foreign zirconium materials, procurement is becoming more and more difficult (high purchase price and long delivery cycle). Obviously, the supply of foreign zirconium materials is far from meeting the needs of various industries in the day.
The demand for zirconium materials provides a rare opportunity for the localization of zirconium materials.
On April 26, 2009, the first domestic complete plant for oxo synthesis with an annual output of 200,000 tons of acetic acid passed the technical appraisal organized by China Chemical Equipment Association. The evaluation given by experts is that the manufacturing level has reached the leading level of similar devices in China, and it can completely replace imports and has broad application prospects. This complete set of acetic acid devices designed by Hefei General Machinery Research Institute and manufactured by Yunnan Dawei Equipment Manufacturing Co., Ltd. consists of 20 devices, including 5 key devices such as a dehydration tower and reactor, all of which are made of zirconium, zirconium-nickel alloy and other special materials. , In the manufacturing process, advanced technologies such as plasma welding, water jet cutting, and helium leak detection are used, which can save about 60 million yuan in equipment purchase costs. The completion of the development of the device has ended the history of my country's inability to design and manufacture complete sets of acetic acid special materials, formed independent intellectual property rights, and broke the foreign technology blockade.
At present, the Southwest Research Institute of Chemical Industry, Hefei General Machinery Research Institute, and other research units have the capacity to design a complete set of oxo acetic acid with an annual output of 200,000 tons. Special equipment manufacturing companies such as Nanjing Smaike Special Metal Equipment Co., Ltd., Western Metal Materials Co., Ltd., Nanjing Baose Co., Ltd., and Yunnan Dawei Equipment Manufacturing Co., Ltd. have the ability to manufacture zirconium equipment. The above enterprises have broken the technical blockade of foreign countries and adopted plasma in the manufacturing process. Advanced technology such as welding, water cutting, and helium leak detection has successfully designed and manufactured complete sets of acetic acid special materials.
