[Project Information] Yangzi Petrochemical’s new 1 million tons/year ethylene and other equipment project has a total investment of 12.67 billion yuan

For the new projects in Yangzi, BASF in the surrounding Yangzi will also have corresponding IPS Phase III projects under construction.

The Nanjing Yangtze-Yangba Light Hydrocarbon Comprehensive Utilization and New Materials project had its environmental impact assessment announced as early as 2018, and has been progressing slowly since then. This time it has been included in the list of major projects in 2022. It is expected that the project will be accelerated this year. The main contents of the project are as follows: Project name: Nanjing Yangzi Petrochemical Co., Ltd. Light hydrocarbon comprehensive utilization and new material transformation project construction unit: Nanjing Yangzi Petrochemical Co., Ltd. project address: Construction scale of Liuhe District, Nanjing City, Jiangsu Province: This project will build a new 1 million tons/year steam cracking ethylene unit, a 350,000 tons/year HDPE unit, a 300,000 tons/year LLDPE unit, a 400,000 tons/year PP unit, a 400,000 tons/year gasoline hydrogenation unit, a 500,000 tons/year aromatics extraction unit, a 35,000 tons/year styrene extraction unit and corresponding system supporting projects. Total project investment: 12,673.77 million yuan

There is also a steam cracking system at Sinopec, and at Tahe Petrochemical, it is also 1 million tons. It seems that this is a way to replace the naphtha route.

Tahe Petrochemical has not started construction either. What are the benefits of steam cracking?

Found in the literature: Converting crude oil directly to chemicals has several benefits compared to processing naphtha, including reduced feedstock costs, energy and emissions savings due to the elimination of the naphtha production step, and the production of a variety of valuable by-products that can be further upgraded into specialty chemicals and other chemical uses. ExxonMobil mastered this technology in 2013, and Sinopec successfully tested it in the Tianjin petrochemical industry in 2021.

Crude oil steam cracking, Huizhou is also preparing to implement one

Sinopec attaches great importance to the research and development and application of direct crude oil to chemicals technology (i.e. "oil conversion" technology) and has independently developed two "oil conversion" technology routes. This crude oil steam cracking technology is one of the "oil conversion" routes, which directly converts crude oil into chemicals such as ethylene and propylene. Another route, crude oil catalytic cracking technology, achieved the world's first industrial application in April this year, which can directly convert crude oil into chemicals such as light olefins and aromatics. On November 17, it was learned from the Sinopec News Office that Sinopec’s key research project “Development and Industrial Application of Light Crude Oil Cracking Technology to Ethylene” was successfully tested in its affiliated Tianjin Petrochemical Industry, which can directly convert crude oil into ethylene, propylene and other chemicals, realizing the first domestic industrial application of crude oil steam cracking technology. This crude oil steam cracking technology is one of the "oil conversion" routes. It "skips" the traditional crude oil refining process and directly converts crude oil into chemicals such as ethylene and propylene, which is equivalent to wheat being directly made into bread, eliminating the need to grind it into flour. this will * * Shorten the production process, reduce production costs, and significantly reduce energy consumption and carbon emissions. This technology was developed and engineered by Beijing Research Institute of Chemical Industry and Engineering Construction Co., Ltd. organized by Sinopec Group Corporation, and industrial trials were carried out at Tianjin Petrochemical Company. Currently, it has applied for 45 Chinese invention patents and 1 international invention patent. It is understood that only ExxonMobil and Sinopec have successfully implemented the industrial application of this technology in the world. It is estimated that for every 1 million tons of crude oil processed using this technology, nearly 500,000 tons of chemicals can be produced, of which nearly 400,000 tons of high-value products such as ethylene, propylene, light aromatics and hydrogen are produced. The overall technology has reached the internationally advanced level and has huge economic value. On April 26, the crude oil catalytic cracking technology independently developed by Sinopec's Petrochemical Science Research Institute successfully conducted an industrial test at Yangzhou Petrochemical, directly converting crude oil into chemicals such as light olefins and aromatics. This is the world's first industrial application of crude oil catalytic cracking technology, marking a breakthrough in my country's direct crude oil to chemicals technology and becoming the world's leader in crude oil catalytic cracking technology. Crude oil catalytic cracking technology is another "oil conversion" route. This technology can also "skip" the traditional crude oil refining process and directly convert crude oil into light olefins and aromatics, significantly increasing the production of high-value chemicals such as ethylene, propylene and light aromatics, while significantly reducing overall energy consumption and carbon emissions. The test results show that the total yield of low-carbon olefins and light aromatics has been increased by 2 times, reaching more than 50%. That is, using this technology to process 1 million tons of crude oil can produce about 500,000 tons of high-value chemicals, which has huge economic value. Ethylene is the basic raw material for chemical products. It is known as the "mother of the petrochemical industry" and is a measure of a * * One of the important symbols of the development level of petrochemical industry. As people's living standards continue to improve, global demand for chemical products continues to grow. As the basic raw materials for chemical products, the demand for ethylene and propylene also continues to grow accordingly. Usually, the raw materials required for the production of ethylene and propylene need to go through the crude oil refining and processing process in the refinery. The production process is long, and only about 30% of the crude oil is used to produce chemical raw materials. The combination of the above two technologies is expected to increase the total amount of chemicals produced from crude oil to more than 70%, and will become an economically feasible technical route for "oil conversion" in the future. It is of great significance to resolve the contradiction between my country's overcapacity in refining and insufficient supply of chemicals. Not only Sinopec has made breakthroughs in the refining and chemical industry, but also PetroChina, which mainly produces upstream oil and natural gas energy products. In August this year, PetroChina achieved two consecutive breakthroughs in the refining and chemical industry - the first time, on August 3, the Yulin ethane to ethylene project was put into operation. ； For the second time, on August 30, the Tarim ethane-to-ethylene project was put into operation. PetroChina’s ethane-to-ethylene project is the first of its kind in China to produce ethylene from ethane cracking, giving China the ability to own large-scale ethylene cracking technology using pure ethane as raw material with independent intellectual property rights. It not only fills the domestic gap but also makes the project possible. The significance of PetroChina's two ethane-to-ethylene projects is not limited to the high-quality development of the company. China has 36 trillion cubic meters of recoverable shale gas reserves. Extracting rich ethane resources from shale gas as an alternative raw material for ethylene plants will also be the most effective and important measure for China's ethylene industry to resist external impacts. The pursuit of a better life cannot be achieved without ethylene. Therefore, ethylene is a commodity in short supply in China. Sinopec and China National Petroleum Corporation are using their respective research and development technology routes to provide ethylene for the Chinese market.

Huizhou's route is no longer crude oil cracking, but a naphtha cracking route.

In addition to Tarim and Changqing, which other gas fields are rich in ethane? ?
