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 thread – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, the world’s first commercial supercritical carbon dioxide power generation unit, “ChaoTan No.1”, was successfully put into operation, marking a significant step forward for China in the field of new energy power generation. The carbon dioxide diaphragm compressor units developed and manufactured by Jiangsu Hengjiu Machinery Co., Ltd. (hereinafter referred to as “Hengjiu Machinery”) play a key role in the closed-loop cycle of the entire system. They compress the low-temperature, low-pressure carbon dioxide fluid efficiently, cleanly, and leak-free to a high pressure in a supercritical state, thereby laying the foundation for the subsequent heat absorption and expansion processes. These units are among the key components that ensure the stable operation of “Chao Carbon No. 1”. As a **highly specialized and innovative “little giant” enterprise, Hengjiu Machinery has been focusing on the field of diaphragm compressors for over 40 years, always taking “technological innovation” as its core driving force. The carbon dioxide diaphragm compressor unit supplied for \"Chao Carbon No.1\" has been fully customized and upgraded in terms of technology, taking into account the high pressure, strong corrosiveness, and unique physical properties of supercritical carbon dioxide. By employing multi-layer metal diaphragm sealing technology, zero-leakage transportation of carbon dioxide is achieved, ensuring perfect compatibility with the harsh operating conditions of supercritical power generation units ； High-precision pressure control and stable gas delivery capabilities ensure the continuous and efficient operation of the supercritical carbon dioxide cycle power generation system, providing essential equipment support for the commercial operation of \"Chao Carbon No. 1\". Against the backdrop of the accelerated advancement of the \"dual carbon\" strategy and the rapid upgrading of the new energy industry, supercritical carbon dioxide power generation has become an important direction for global energy transformation, thanks to its key advantages of high efficiency, low energy consumption, and reduced carbon emissions. Leveraging over 40 years of technical expertise in diaphragm compressors, Hengjiu Machinery has not only made significant breakthroughs in the field of supercritical carbon dioxide power generation equipment; its products are also used across a range of key sectors in the new energy industry, including hydrogen storage and transportation, photovoltaic silicon material production, and the delivery of high-end specialty gases. Adhering to the product philosophy of \"customization, high-end quality, and intelligence,\" the company offers one-stop equipment solutions tailored to the specific needs of various application scenarios, providing equipment support for the high-quality development of industries such as new energy and semiconductors.
