Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. Your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】A continuously updated summary post is available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** The first domestically produced feed pump for coal-to-oil production has been successfully put into use. As of August 3, 2024, the five-plunger oil-coal slurry feed pump developed by this company has been operating stably for over 5,000 hours, successfully meeting all the required performance criteria. This marks a breakthrough in breaking foreign technological monopolies in this field, providing reliable equipment support for the implementation of coal-to-oil projects, and it holds positive significance for advancing China’s efforts to become a manufacturing powerhouse. The oil-coal slurry feed pump is a key component of the million-ton-scale direct coal liquefaction demonstration project. Its main function is to raise the pressure of the low-pressure oil-coal slurry, which has a solid content of 50%, and transport it to the oil-coal slurry heater for heating, before it enters the coal liquefaction reactor where the hydrogenation reaction takes place. This equipment operates for extended periods under harsh conditions of high pressure and high solid content, which makes it difficult to design and requires high standards in production; it has previously relied on imports. To meet the demands for domestic production and larger-scale equipment in high-flow conditions, the company’s task force focused on the domestic development of oil-coal slurry feed pumps worked together with domestic manufacturers to address various technical challenges related to structural design, material selection, sealing and flushing methods, as well as manufacturing processes. By adopting a pump structure designed to prevent sedimentation and a special hydraulic end design, issues such as the short lifespan of vulnerable components in imported pumps and inadequate design of the feed collection pipes were resolved. The rated flow rate of these pumps has increased by 25% compared to before; they are now the high-pressure, high-solid-content coal slurry piston pumps with the highest flow rates available. After being produced domestically, their price and delivery time have decreased significantly compared to imported versions, thereby reducing project costs and equipment maintenance expenses substantially. Throughout the years, the company has thoroughly implemented the new energy security strategy of \"Four Revolutions and One Cooperation\" as well as the innovation-driven development strategy. By collaborating with large domestic equipment manufacturers, research institutions, and universities, it has actively worked on developing domestic versions of the key equipment needed for direct coal liquefaction, filling several gaps in China’s technological capabilities and making significant contributions to ensuring energy security.
