With the rapid expansion of Sinopec's new projects and the modernization of existing facilities, numerous foreign companies have taken advantage of China’s booming petrochemical industry to engage in technology transfer and project contracting using their proprietary and advanced technologies. This collaboration not only accelerates the development of China’s petrochemical infrastructure but also fosters mutual benefits between Chinese and international partners. One significant example is CNPC’s investment in a world-scale oil refinery in Dushanzi, capable of processing 10 million tons per year, along with an ethylene plant producing 1.2 million tons annually. This project is a key component of energy cooperation between China and Kazakhstan. In January 2005, the refinery project incorporated UOP technology from the United States, while leading engineering firms like Linde were also involved in the project’s execution. Sinopec and CNOOC have partnered with global giants such as BASF, Shell, and BP to establish a joint petrochemical venture. This has attracted several multinational firms. For instance, JGC (Japan Volkswagen) was responsible for constructing the Huizhou cracker, the Nanjing ethylene oxide/ethylene glycol plant, and the pure benzene and butadiene unit in Nanhai. Meanwhile, a Japanese consortium led by Chiyoda handled the styrene/epoxy and propane plants in Nanjing, with Mitsubishi assisting in the South Sea project. Lummus has a long-standing presence in China, having supplied its technology for the country’s first large-scale ethylene plant at Beijing Yanshan Petrochemical. Since then, Lummus has executed over 80 projects in China, with 60% of the nation’s ethylene and styrene capacity relying on its technology. Its largest project in the country is the ethylene and ethylbenzene/styrene monomer units at Shanghai Secco, where it collaborates with Sinopec on highly selective pyrolysis furnaces. Basel is also actively transferring polyolefin technology to China. It signed a second Lupotech T patent agreement with PetroChina for the Lanzhou LDPE plant and provided Spheripol technology for the PP plant. To date, five Lupotech T licenses have been transferred in China, making it a preferred choice for LDPE production. Technip-Coflexip used BP’s Innovene technology to build two PE units for Shanghai Secco, and also constructed the world’s largest polytetrahydrofuran/tetrahydrofuran integrated facility, fully operational since 2023. Held-Topsoe recently signed two contracts with China for methanol synthesis loop technology, which will be used to build two new methanol plants. The deal includes technology, engineering services, catalysts, and equipment supply. Other chemical projects have also benefited from foreign technology. Jilin Petrochemical’s carbonyl alcohol plant is the fourth implementation of Kvaerner Process Technology (KPT)/Dow’s carbonyl synthesis process in China. Shanghai Petrochemical uses Borealis’ Borstar technology to construct the world’s largest 250,000-ton/year bimodal PE unit. UDE employs Basel Hastalen technology for HDPE equipment in Jilin, while Novolen Technology Holdings provides PP technology for Fujian’s petrochemical project. Additionally, Singapore SembCorp and Taiwan’s CTCI built a LDPE plant for Nanjing Yangba Petrochemical, Foster-Wheeler constructed an isocyanate complex in Shanghai, and Aker Kvaerner expanded an acetic acid plant for Chongqing Yangtze River Acetyl. Foreign technology has also helped Chinese companies grow. China Bluestar (Group) Corp. and British Davy Technology signed a contract for a 55,000-ton/year 1,4-butanediol project, with Davy providing its fourth-generation technology. Once completed, this project will strengthen Bluestar’s product chain and enhance its global competitiveness, while advancing domestic 1,4-butanediol production capabilities.

Braille Cards

Braille cards are typically made from durable materials, such as plastic or heavy-duty cardstock, to ensure they can withstand frequent use. The braille markings are raised and easily distinguishable, enabling players to feel the patterns and read the cards without difficulty.These cards are used in various card games, including popular ones like poker, blackjack, and bridge. They provide an inclusive and accessible gaming experience for individuals with visual impairments, allowing them to participate and enjoy playing card games with their sighted friends and family members.Braille cards are an essential tool for promoting social interaction, entertainment, and cognitive stimulation among individuals who are blind or visually impaired. They help foster inclusivity and equal participation in recreational activities, ensuring that everyone can enjoy the fun and challenges of card games.
