The 800,000-ton full-density polyethylene plant was successfully started up in o02 23,2023
Guangdong Petrochemical's 800,000-ton/year full-density polyethylene plant is PetroChina's first full-density polyethylene plant with "one head and two tails" double-line arrangement, and it is also the second full-density polyethylene plant with the largest production capacity in China. The device adopts UNIPOL process and single-reactor gas-phase fluidized bed process. It uses ethylene as the main raw material and can produce 15 kinds of LLDPE and HDPE polyethylene materials. Among them, the full-density polyethylene resin particles are made of polyethylene powder mixed with different types of additives, heated at a high temperature to reach a molten state, and under the action of a twin-screw extruder and a molten gear pump, they pass through a template and are processed underwater by a cutter. Granulation formation. Under normal working conditions, a single line can produce 60.6 tons of polyethylene pellets per hour. It is reported that the production line process uses ethylene as the main raw material and butene-1 or hexene-1 as the comonomer to produce linear low-density and some medium and high-density polyethylene granular resins. As of press time, the production line has successfully completed the whole process of refining-polymerization-degassing-recycling-extrusion granulation, the product indicators are qualified, and the production load is gradually increasing. Guangdong Petrochemical's 800,000-ton/year full-density polyethylene plant line I is scheduled to start operation in 8 days. The full-density polyethylene plant started on-site on September 14, 2020. During the construction period, the full-density polyethylene sub-project department gave full play to the advantages of the "general-department" integrated management model, united forces from all parties, fully carried forward the oil spirit and the Daqing spirit, and took the initiative to attack without waiting or relying on the project location. High temperature and high humidity, rainy and typhoon and other adverse effects. The party branch of the sub-project department gave full play to the role of the battle fortress, and successively organized a series of labor competitions such as "working hard for 60 days", "sprinting for the fourth quarter, and winning 3.30". , built a solid line of defense for safety and quality, ran out of the "acceleration" of project construction, and finally realized the mid-delivery of the device on June 27, 2022, which lasted 21.5 months. In the production preparation stage, in line with the attitude of "handing over the installation but not responsibility", and continuing to practice the concept of "the success of the owner's project is what the world wants", the full-density polyethylene sub-project department further upgraded the management, and the heart of the installation - the response system With the granulation system as the core, the load test run of large units, pickling and air-tightness of the process pipeline system, catalyst loading of raw material refining, and joint debugging of electrical instruments have been carried out in an orderly manner. Management personnel interspersed with on-site operations in depth to further speed up the "three investigations and four determinations" final items and PSSR sales items. The full-density polyethylene sub-project department has always maintained "resonance at the same frequency" with the owner. The design and driving team sticks to the site, with a sense of responsibility of "always rest assured", and goes all out to cooperate to solve hidden dangers in the pre-testing process, and carefully confirm the preparation status of the catalyst system , The injection of the chromocene system, and the strict implementation of various process parameters have laid a solid foundation for the successful start-up of the device at one time. In the initial stage of plant operation, the full-density polyethylene sub-project department will insist on serving wholeheartedly to ensure that the plant enters a period of stable production and operation, completes performance assessment, and contributes to the company's high-quality development.

What is the impact of a strong earthquake in Turkey on polyethylene?02 10,2023
Turkey is a country straddling Asia and Europe. It is rich in mineral resources, gold, coal and other resources, but lacks oil and natural gas resources. At 18:24 on February 6, Beijing time (13:24 on February 6, local time), a magnitude 7.8 earthquake occurred in Turkey, with a focal depth of 20 kilometers and an epicenter at 38.00 degrees north latitude and 37.15 degrees east longitude. The epicenter was located in southern Turkey, close to the border of Syria. The main ports in the epicenter and the surrounding area were Ceyhan (Ceyhan), Isdemir (Isdemir), and Yumurtalik (Yumurtalik). Turkey and China have a long-standing plastic trade relationship. my country's import of Turkish polyethylene is relatively small and is decreasing year by year, but the export volume is gradually increasing by a small amount. In 2022, my country's total polyethylene imports will be 13.4676 million tons, of which Turkey's total polyethylene imports will be 0.2 million tons, accounting for 0.01%. In 2022, my country exported a total of 722,200 tons of polyethylene, of which 3,778 tons were exported to Turkey, accounting for 0.53%. Although the proportion of exports is still small, the trend is increasing year by year. The domestic polyethylene production capacity in Turkey is very small. There are only two polyethylene plants located in Aliaga, both belonging to Petkim producer and the only polyethylene producer in Turkey. The two sets of units are 310,000 tons/year HDPE unit and 96,000 tons/year LDPE unit. Turkey's polyethylene production capacity is very small, and its polyethylene trade with China is not large, and most of its trading partners are concentrated in other countries. Saudi Arabia, Iran, the United States, and Uzbekistan are the main HDPE importers of Turkey. There is no LLDPE plant in Turkey, so all LLDPE depends on imports. Saudi Arabia is the largest import supplier of LLDPE in Turkey, followed by the United States, Iran, and the Netherlands. Therefore, the impact of this earthquake disaster on global polyethylene is almost negligible, but as mentioned above, there are many ports in its epicenter and surrounding radiation zone, among which Ceyhan (Ceyhan) port is an important crude oil transportation port, and the crude oil export volume Up to 1 million barrels per day, crude oil from this port is transported to Europe via the Mediterranean Sea. Operations at the port were suspended on Feb. 6, but supply concerns eased on the morning of Feb. 8 when Turkey ordered oil shipments to resume at the Ceyhan oil export terminal.

Sinopec made a breakthrough in the development of metallocene polypropylene cata01 11,2023
Recently, the metallocene polypropylene catalyst independently developed by the Beijing Research Institute of Chemical Industry successfully completed the first industrial application test in the ring pipe polypropylene process unit of Zhongyuan Petrochemical, and produced homopolymerized and random copolymerized metallocene polypropylene resins with excellent performance. China Sinopec became the first company in China to successfully independently develop metallocene polypropylene technology. Metallocene polypropylene has the advantages of low soluble content, high transparency and high gloss, and is an important direction for the transformation and upgrading of the polypropylene industry and high-end development. Beihua Institute started the research and development of metallocene polypropylene catalyst in 2012. After small test, model test and pilot test scale-up preparation, it solved technical problems such as catalyst structure design, preparation process and catalytic activity optimization, and successfully developed metallocene polypropylene catalyst. Propylene catalyst technology and the production of catalyst products. In the comparative evaluation under the same polymerization conditions, the catalyst has higher activity than the imported catalyst, and the prepared polypropylene product has better particle shape and no agglomeration. Since November this year, the catalyst has successively completed industrial tests in the Hypol process polypropylene plant of Yangzi Petrochemical and the ring pipe process polypropylene plant of Zhongyuan Petrochemical, and obtained good verification results. This industrial test in Zhongyuan Petrochemical is the first time in China to produce random copolymerized metallocene polypropylene on a ring pipe polypropylene device, which has laid a solid foundation for the high-end development of Sinopec's polypropylene industry.

2022 Polypropylene Outer Disk Review.01 06,2023
Compared with 2021, the global trade flow in 2022 will not change much, and the trend will continue the characteristics of 2021. However, there are two points in 2022 that cannot be ignored. One is that the conflict between Russia and Ukraine in the first quarter has led to a surge in global energy prices and local turmoil in the geopolitical situation ; Second, US inflation continues to rise. The Federal Reserve raised interest rates several times during the year to ease inflation. In the fourth quarter, global inflation has not yet shown a significant cooling. Based on this background, the international trade flow of polypropylene has also changed to a certain extent. First, China's export volume has increased compared to last year. One of the reasons is that China's domestic supply continues to expand, which is higher than last year's domestic supply. In addition, this year, there have been frequent restrictions on movement in some areas due to the epidemic, and under the pressure of economic inflation, the lack of consumer confidence in consumer consumption has suppressed demand. In the case of increased supply and weak demand, Chinese domestic suppliers turned to increase the export volume of domestic goods, and more suppliers joined the ranks of exports. However, as mentioned above, global inflationary pressures have increased sharply and demand has weakened. Overseas demand is still limited. Imported resources have also been in an upside-down state for a long time this year. The import window has gradually opened in the second half of the year. Imported resources are subject to changes in overseas demand. In the first half of the year, demand in Southeast Asia and other places is strong and prices are better than those in Northeast Asia. Middle Eastern resources tend to flow into regions with high prices. In the second half of the year, as the cost of crude oil fell, suppliers with weak overseas demand began to lower their quotations for sales to China. However, in the second half of the year, the exchange rate of RMB against the US dollar exceeded 7.2, and the pressure on import costs increased, and then gradually eased. The highest point during the five-year period from 2018 to 2022 will appear from mid-February to the end of March 2021. At that time, the highest point of wire drawing in Southeast Asia was US$1448/ton, injection molding was US$1448/ton, and copolymerization was US$1483/ton; Far East drawing was US$1258/ton, injection molding was US$1258/ton, and copolymerization was US$1313/ton. The cold wave in the United States has caused a decline in the operating rate in North America, and the flow of foreign epidemics has been restricted. China has turned to the center of the "world factory", and export orders have increased significantly. Until the middle of this year, overseas demand gradually weakened due to the impact of the global economic recession, and foreign companies began to underestimate due to sales pressure, and the price difference between internal and external markets was able to narrow. In 2022, the global polypropylene trade flow will basically follow the general trend of low prices flowing into high price regions. China will still mainly export to Southeast Asia, such as Vietnam, Bangladesh, India and other countries. In the second quarter, exports were mainly to Africa and South America. Polypropylene exports radiated many varieties, including wire drawing, homopolymerization and copolymerization.The year-on-year decrease in sea freight this year is mainly due to the lack of consumption power in the expected strong market due to the global economic downturn this year. This year, due to the conflict between Russia and Ukraine, the geopolitical situation in Russia and Europe was tense. Europe’s imports from North America increased this year, and imports from Russia remained good in the first quarter. As the situation entered a stalemate and sanctions from various countries became clear, Europe’s imports from Russia also decreased. . The situation in South Korea is similar to that in China this year. A large amount of polypropylene is sold to Southeast Asia, occupying the market share in Southeast Asia to a certain extent.
