Thread Content
On June 12, the "Third Generation" domestically produced PTA complete set of technology seminar and exchange meeting was held at Zhongtai Petrochemical, hosted by China Kunlun Engineering Company (hereinafter referred to as "Kunlun Engineering Company") and hosted by Xinjiang Korla Zhongtai Petrochemical Co., Ltd. (hereinafter referred to as "Zhongtai Petrochemical"). Zhou Huatang, deputy director of the Consulting Center of China National Petroleum Corporation, Li Lijun, deputy general manager of China Kunlun Engineering Company, Lu Zhengping, chairman of Zhongtai Petrochemical, Jiang Yunfei, general manager of Zhongtai Petrochemical, Yang Ming, general manager of Pengwei Petrochemical Company, and relevant leaders of Reignwood Petrochemical, Honggang Petrochemical Company, Urumqi Petrochemical Company, and Hailun Petrochemical Company participated in the technical exchange. The meeting analyzed and explained the development trends of the international PTA industry and the competitive landscape of "third generation" domestic PTA technology. It focused on the exchange of key technologies related to safety and environmental protection, energy saving and consumption reduction, quality improvement and efficiency improvement of "third generation" domestic PTA, and conducted interactive discussions on this technology. At the exchange meeting, Zhou Huatang and Li Lijun respectively elaborated on the purpose and significance of this exchange meeting. Li Lijun said that the "third generation" domestically produced PTA complete set of technology has verified the reliability of the process technology during the production and operation of Zhongtai Petrochemical through continuous technical optimization, continuous process improvement, and perfect production processes. It is believed that in the future, with the joint efforts of all enterprises, the "third generation" domestically produced PTA technology can make outstanding contributions to building our country into a major textile country and a powerful textile country. Lu Zhengping said that Zhongtai Petrochemical's annual output of 1.2 million tons of PTA project connects the downstream polyester refining of oil and coal, which has far-reaching significance for opening up the refining-chemical fiber-blending-textile and clothing industry chain and improving the structure of Xinjiang's chemical industry. Since the first half of this year, the company's main production unit, the PTA device, has achieved safe, stable and high-load continuous production, with stable product quality. ； The boiler system, utility system and storage and transportation system of the auxiliary production unit operate smoothly, are safe and controllable, and meet environmental protection standards. In the next step, Zhongtai Petrochemical will continue to strengthen business cooperation and resource sharing with various brother companies, build a good communication platform, continue to optimize process operations, and strive to become a benchmark company in the PTA industry. It is understood that the main companies in the world that master PTA production process technology include BP-AMOCO, INVISTA, Mitsubishi Chemical, IEC-Hitachi Technology, Kunlun Engineering Company and many other units. Among them, Kunlun Engineering Company is the only large-scale survey and design unit in China's textile industry that integrates consulting, research and development, design, procurement, construction management, start-up guidance and project supervision, general engineering contracting, project management contracting, technical services and other multi-functional international engineering companies.

Before 2000, the production capacity of PTA was less than 1.5 million tons. With the blowout of the polyester market, by 2008, the domestic* * Xiaoxiao has introduced more than 20 sets of PTA devices. However, behind the seemingly hot market are many distressing facts. These patented technologies all come from abroad. For each set of devices, Chinese companies need to pay a huge patent fee of about US$20 million. This reality deeply hurt the hearts of technicians, prompting them to embark on the road of independent research and development of PTA technology.
The PTA technology development team was formally established in 2000. The members include* * A total of more than 40 people, including design masters, professors, senior engineers, and engineers, have a very strong technical force. At the beginning of development, the leaders of Kunlun Engineering Company were under tremendous pressure to vigorously promote the development and research of PTA patented technology, and went deep into the development team to participate in overcoming every technological difficulty. The 70-year-old veteran experts in the team have deep feelings for PTA. Even after retirement, they are still fighting on the front line of scientific and technological development. At critical moments, they often have a high position to clear up the fog for comrades and point out the correct direction of scientific and technological development. Young technicians with high academic qualifications, quick thinking, and excellent professional knowledge join the R&D team.
In 2004, the team developed the first PTA technology software package with China's independent intellectual property rights. In 2007, the first set of equipment using domestically produced PTA technology was invested and constructed in Fuling, Chongqing. In 2009, the device was successfully started at one time, and all consumption indicators met the contract requirements.
From 2000 to the present, in the past two decades, the PTA technical team has been led by the old and the new, and three generations of scientific and technical personnel, old, middle and young, have alternated between the old and the new. The team has continued to grow, and the level of technical capabilities has continued to improve. Team members have always adhered to the concepts of innovation and competition, worked hard and strive for excellence in the field of PTA technology, and successfully completed each high-quality project, and also created a technical team that can fight tough battles and dare to fight and compete. In 2011, the PTA technical team lived up to their responsibilities and successfully developed the second-generation PTA technology featuring low-pressure and ultra-low-pressure waste heat power generation technology, reducing the energy consumption of PTA per ton of product from 100 to less than 80 standard oil, reaching the leading domestic level. And the single production capacity of the device has been expanded from 900,000 tons to 1.2 million tons and 1.4 million tons, reaching a new level in terms of technology.
In 2015, the technical team further upgraded and improved on the basis of the second-generation PTA technology and developed the third-generation PTA technology represented by the reuse of refined mother liquor, which reduced the energy consumption per ton of product from 77 standard oil to about 55 standard oil. The unit consumption of the main raw material PX also dropped from the initial 657kg/ton of product to 649kg/ton of product. The single-set production capacity of the device reached 2.5 million tons. The energy consumption and material consumption indicators of the third-generation PTA technology have reached the international advanced level.
Key technologies must not be shared casually. BP does a better job of keeping technology confidential. There is a phenomenon in China that in order to publish articles or show off, the results of hard-earned research are often given away, and the awareness of confidentiality and intellectual property rights is relatively low.
