Recently, Shaanxi Blower (Group) Co., Ltd. signed a 600,000-ton/year PTA equipment supply contract with Dongfang Hope Group Chongqing Pengwei Petrochemical Company, marking that Shaanxi Drum Process Air Compressor formally entered the PTA field and will be equipped with large-scale PTA equipment. Localization provides support.
Since the beginning of the development of the polyester industry in China in the late 1970s, nearly 20 PTA installations have been built in the country. Basically, they have introduced foreign patented technologies. Due to the high introduction cost of PTA key technologies and equipment, the production cost is high and the competitiveness is weak compared with foreign products. Therefore, the adoption of domestic technology and equipment is an important channel for the PTA industry to reduce investment costs and improve product competitiveness.
The process air compressor unit is one of the core equipment of the PTA plant and can provide air for the paraxylene oxidation reaction and recover some of the energy. Shaanxi Drum has mastered system technologies such as axial compressors, energy recovery turbines, and centrifugal compressors, as well as multi-unit set technology through the study of process systems and multi-machine sets. Up to now, nearly 2,000 units have been designed and completed. (Sets) Large-scale units. During more than ten years, Shaanxi Drum continued to invest funds in axial compressors and energy recovery devices to continue scientific research and re-innovation, so that the product's aerodynamic design technology, structural design technology, processing technology, automatic control, testing, The installation and commissioning as well as the machine set technology have reached the international advanced level, and thus won the second prize of national scientific and technological progress. In terms of centrifugal compressors, Shaanxi Drum has formed a high-pressure special medium centrifugal compressor design, manufacture and complete sets of technology with independent intellectual property rights through the combination of production, study and research, and has designed and manufactured suitable rich gas, synthesis gas, nitrogen oxide, and carbon dioxide. , Recycle gas, natural gas, hydrogen, gas, cracked gas, raw gas and other medium centrifugal compressor. At the same time, Shaanxi Drum's compressor technology and equipment have achieved remarkable results in the fields of coal chemical industry and air separation.
It is understood that the Pengwei petrochemical project is one of the 10 key new construction projects for the Western Development in 2007. After completion and production at the end of 2008, it will produce an annual output of 600,000 tons of PTA. The project will adopt mature domestic process technology. After the project is completed, it is expected to become one of the petrochemical projects with the highest localization rate, the lowest investment cost, the fastest construction speed, and the most competitive petrochemical projects, and will promote the localization of major technical equipment. It is of great significance.
