Thread Content
The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! ***********************************
The new type of centrifugal compressor jointly developed by SHENGU Group and Jiangsu Yanchang CNPC Chemical Co., Ltd. has successfully passed the factory testing phase and is now ready to enter the stage of on-site installation and commissioning. Low-carbon olefins are important basic organic chemical raw materials, which are primarily produced as a by-product or through co-production in processes such as steam cracking and refinery catalytic cracking. Their production is largely constrained by the output of ethylene as well as gasoline and diesel, making it difficult to meet the rapidly growing market demand. The overall propylene yield of the PHD process can reach 80%–90%, which is much higher than the 33% achieved by steam cracking; moreover, the equipment investment required is about 30% lower compared to hydrocarbon cracking. In China, the product gas compressors used in PDH units are generally imported; this results in long manufacturing cycles, high capital investment, and high maintenance costs later on. Localizing these equipment will bring long-term economic benefits to enterprises. Developed based on the LUMMUS process technology for the compressor of product gas in a 600,000-ton/year propane dehydrogenation (PDH) plant, this product is a key core equipment for the expansion of the Phase I project of Zhongran, and it constitutes a technology-intensive type of major equipment. The compressor features a configuration of \"motor + gearbox + high-pressure cylinder + low-pressure cylinder\", enabling two-cylinder, three-stage compression; it has a power output of 37 megawatts and an impeller diameter of 1.5 meters. The first stage of the unit features a dual-air-inlet design, with a volumetric flow rate equivalent to that of 100,000-class air separation compressors. It is China’s first domestically produced compressor for PDH units, ending the reliance on foreign technology in such equipment in the country; its performance metrics are currently at the world’s leading level.

The total investment in the expansion of the Zhongran Taixing light hydrocarbon deep processing project is approximately 10 billion yuan, with construction taking place in two phases. One phase of this investment involves around 3.8 billion yuan, with a land area of approximately 500 mu, to build a propane dehydrogenation plant with an annual capacity of 600,000 tons, along with associated utility facilities ； The second-phase investment amounts to approximately 5.8 billion yuan, with a land area of around 496 mu; it involves the construction of a propane dehydrogenation plant with an annual capacity of 600,000 tons, a polypropylene plant with an annual capacity of 300,000 tons, as well as facilities for producing high-value-added downstream products.
Shenmu Group Signs Technical Cooperation Agreement to Expand 600,000-ton PDH Plant of Yanchang CNPC Chemical 2022-01-11 15:03 Recently, a signing ceremony for the technical cooperation agreement between Shenyang Blower Group Co., Ltd. (referred to as “Shenmu Group”) and Jiangsu Yanchang CNPC Chemical Co., Ltd. (referred to as “Yanchang CNPC Chemical”) was held at Shenmu Group. Li Da, General Manager of Zhongran Chemical, and Shan Gu Group’s Deputy General Manager Shan Wei attended the ceremony. Before the signing ceremony, the two sides had a friendly exchange. Shan Gu Group’s vice general manager, Shan Wei, welcomed Li Da and his team from Yanchang CNPC Chemical to the group, and expressed his gratitude for the high level of trust and strong support that Yanchang CNPC Chemical has always shown toward Shan Gu Group. Shan Wei said that extending the CNRG project is of great significance to both parties. SHENGU Group will concentrate its superior resources and leverage its strengths to meet top-tier equipment standards, delivering satisfactory results to its customers and achieving a breakthrough of \"zero\" in terms of domestic production for the gas compressors and heat pump compressors used in PDH plants with an annual production capacity of 600,000 tons. Li Da, General Manager of Yanchang Zhongran Chemical, expressed his appreciation for SHENGU Group’s capabilities in research and development, manufacturing, and service quality. He said that the plant with an annual production capacity of 600,000 tons of PDH is Yanchang Group’s first chemical project outside the province, as well as Zhongran Group’s first physical facility, and it holds a symbolic significance. At present, the compression unit for this project has entered a crucial phase of manufacturing. It is hoped that through further cooperation, both parties will enhance their mutual trust and deepen their partnership, working together to ensure the project is completed on schedule and thus writing another chapter in the advancement of domestic production of major equipment. Subsequently, the two parties signed a technical cooperation agreement.
According to the Liaoning Daily, reporters learned on February 1, 2021, that the product gas compression units, propylene compression units, and ethylene compression units required for Fujian Meide Petrochemical Co., Ltd.’s 900,000 tons per year propane dehydrogenation to produce propylene (PDH) project would be supplied by Shenhua Gas Turbine Group. This means that Shenhua Gas Turbine Group has successfully won the bid for the world’s largest propane dehydrogenation to produce propylene project using the Lummus process. Fujian Meide Petrochemical Co., Ltd.’s 900,000 tons per year propylene production via propane dehydrogenation (PDH) project utilizes the Lummus process, and it is currently the largest facility of its kind in the world to employ this process. The successful bid for this project marked a significant breakthrough in the localization of compression units used in this process, and it strongly promoted the progress toward fully localizing the compression units employed in the Lummus process within the propane dehydrogenation to propylene (PDH) industry.
According to public data, the propane feedstock required for the normal operation of Fujian Meide’s propane dehydrogenation plant is supplied by Fujian Tianhui Petrochemical Logistics Co., Ltd. It is understood that the first ship carrying frozen propane, amounting to about 10,000 tons, arrived at the port in the first half of November 2019. In addition, the second-phase 900,000-ton PDH project is expected to start construction within this year. As early as November 2019, the official website of the People’s Government of Fuqing City, Fuzhou, issued a announcement regarding the approval decision for the \"900,000-ton per year propylene production project via propane dehydrogenation carried out by Fujian Meide Petrochemical Co., Ltd.\" To ensure the supply of propylene monomer, Fujian Meide Petrochemical Co., Ltd. plans to adjust the process and scale of the production facilities in its existing Phase II project. The production process will be modified to use the Catofin process developed by the American company Lummus for the hydrogenation of propane to produce propylene monomer, with the production capacity to be increased to 900,000 tons per year of propylene products. The propane, which is the raw material required for this project, will be imported from countries such as the United States, the Middle East, Indonesia, and Australia. The propylene produced will be used in the normal operation of the PP plants owned by Zhongjing Petrochemical and Zhongjiang Petrochemical. The construction of the propane dehydrogenation project creates a complete industrial chain that goes from propane dehydrogenation to produce propylene, followed by propylene polymerization to produce polypropylene, and finally the processing of polypropylene into BOPP – this will significantly enhance the competitiveness of China Soft Packaging Group.
