Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. By contributing our ideas, we can foster more active participation from everyone. HaiChuan becomes even better with your involvement; we welcome everyone to participate more actively in discussions on this forum. Everyone should focus on safety and know how to handle emergencies. ********************************************* On June 21st, the official website of Shandong Dongming Petrochemical Group published a draft document seeking public opinions regarding the environmental impact assessment of Dongming Shenghai Chemical New Materials Co., Ltd.’s 300,000 tons per year UPC technology pilot project. The project mainly involves the construction of a 300,000 t/a UPC test unit, a 100,000 t/a butadiene extraction unit, 80,000/50,000 t/a MTBE/butene-1 units, a 550,000 t/a light aromatic hydrocarbons hydrogenation unit, and a 350,000 t/a aromatic hydrocarbons extraction unit. It also includes auxiliary and utility facilities such as power stations, circulating water systems, power transformation and distribution systems, and storage and transportation tank areas. 1.06 million tons of crude oil are processed per year. The predecessor of Dongming Petrochemical, the Dongming County Petroleum Chemical Plant, was established in 1987, and the current company was formed in 1997. Dongming Petrochemical is a mega-scale petrochemical enterprise group that focuses on basic oil refining and high-end chemical production, and integrates international trade, international logistics, retail sales, and more, forming a complete industrial chain. The Dongming petrochemical industry is distributed across five major bases in Dongming, Jiangsu, Rizhao, and other locations abroad, with overseas offices and international trade companies established in Beijing, Shanghai, Jinan, Rizhao, **, Singapore, and other places. Dongming Petrochemical holds the qualifications for importing fuel oil and for wholesaling refined petroleum products ； In 2015, it became the first among local private oil refining enterprises across the country to obtain the qualification to use imported crude oil as well as the qualification for non-state-owned trade in crude oil, with an allowed annual import volume of 7.5 million tons.
We welcome everyone to participate more in the forum discussions
Construction unit: Dongming Shenghai Chemical New Materials Co., Ltd. Project name: 300,000 tons/year UPC technology demonstration project. Location of construction: The plant is situated in the Dongming Petrochemical Industrial Park, at geographical coordinates of approximately 35°20′4″ north latitude and 115°8′9″ east longitude. Construction scale: Total investment of 1,107 million yuan, with a total land area of 93.24 hectares. Construction contents: The main facilities to be built include a 300,000 t/a UPC test unit, a 100,000 t/a butadiene extraction unit, 80,000/50,000 t/a MTBE/butene-1 units, a 550,000 t/a light aromatic hydrocarbons hydrogenation unit, and a 350,000 t/a aromatic hydrocarbons extraction unit. In addition, auxiliary and utility facilities such as power stations, circulating water systems, power transformation and distribution systems, and storage and transportation tank areas will also be constructed. 1.06 million tons of crude oil are processed per year. Working system: The design of the production unit takes an annual operating time of 8,000 hours into account. The proposed project will employ 989 workers, with a production schedule organized in four shifts operating three times a day.
Low-carbon olefins (such as ethylene, propylene, butenes, and butadiene) are very important basic raw materials in the organic chemical industry; in particular, the production capacity of ethylene is often regarded as an indicator of a region’s level of development in the petrochemical sector. The Upstream Cracking Process (UPC) involves first separating crude oil into light and heavy fractions, which are then cracked in a double riser reactor using catalysts under appropriate operating conditions. The total yield of low-carbon olefins and light aromatics in the products can exceed 50% (about twice that of conventional processes). The biggest advantage of the technology for producing olefins directly from crude oil is that it eliminates refining units such as atmospheric and vacuum distillation, thereby significantly shortening the process flow. However, it has a narrow range of suitable feedstocks and requires harsh operating conditions. The most representative technologies are ExxonMobil technology and Saudi Aramco/SABIC technology.
