The reporter learned on the 26th that the PTA (pure terephthalic acid) project with an annual output of 1 million tons, which has the lowest investment, the fastest progress, and the highest localization rate of equipment (greater than 75%), is currently under construction in China. The project construction of Granville PTA has progressed smoothly and the goal of realizing the localization of large-scale PTA project equipment is just around the corner.
The Pengwei PTA project in Chongqing is a large petrochemical project invested by Dongfang Hope Group. As a privately-owned company, the company undertook the approval of the domestic design institute's process design and the level of domestic equipment manufacturing, and assumed the responsibility for the first domesticization of the first major petrochemical equipment. The project adopts the domestically-developed PTA process technology developed by the China Textile Industry Design Institute, which provides convenient conditions for the localization of key equipment.
It is understood that Chongqing Pengwei PTA project was designed with an annual output of 600,000 tons. With the upgrade of the economic scale of the installation, it has been adjusted to an annual output of 900,000 tons. With the design margin, the annual output can reach 1 million tons. As the realization of the process of domestic production and key equipment based on domestic manufacturing will greatly reduce the project cost, it is estimated that the total project investment is 2.644 billion yuan. In particular, the large-scale PTA plant process air compressor unit is the first realization of localization after more than 20 sets of imports in China. The air compressor unit can meet the process requirements in a stable and reliable manner, significantly saving equipment cost.
At present, some long-period devices that have been demonstrated by experts and have clear opinions have been ordered in Chongqing Pengwei PTA project. Including the PTA device's core equipment and supporting devices, all of which are Shaanxi Blower Group Co., Ltd., Hangzhou Steam Turbine Co., Ltd., Jinxi Chemical Machinery Manufacturing Co., Jiangsu Nanjing Baosili Titanium Industry Co., Ltd., Chengdu Xiangyun Aircraft Accessories Factory, and Aerospace Science and Technology Power. Institute and other design and manufacturing. Designed by China Textile Institute, the large-scale hydrotreating reactor manufactured by China Erzhong Group is the first domestic large-scale PTA refining reactor.
According to the “Implementation Plan for Accelerating Large-scale Petrochemical Equipment Autonomous Implementation†recently released by the National Development and Reform Commission, the goal of independently designing and manufacturing petrochemical complete sets of equipment such as 600,000 to 1 million tons/year of large-scale PTA during the “Eleventh Five-Year Plan†period is to achieve an autonomy rate. 75% or more. Yizheng Chemical Fiber, Jinan Chemical New Materials and Chongqing Pengwei Petrochemical Co., Ltd. three large-scale PTA projects have been identified as the projects relying on the localization of large-scale PTA project equipment.
