There has been significant development in chemical processing equipment over the past decade; let’s celebrate the prosperity and strength of modern China. This is just a starting point – more participation from everyone will make things even more lively. The HaiChuan forum becomes better with your involvement; we welcome everyone to engage more in discussions here. With the high temperatures in July, be careful to prevent fires. ********************************************* In June 2023, Yanchang Zhongran’s 600,000 tons per year propane dehydrogenation plant was successfully commissioned after a single trial run, producing qualified products. It has now been operating steadily for over 200 hours, marking a complete success for the first trial run of Yanchang Zhongran’s Taixing light hydrocarbon deep processing project. Shenmu Group provided a total of four sets of centrifugal compressor units for the Zhongran Taixing Light Hydrocarbons Deep Processing Project, including product gas compressors, heat pump compressors, propylene compressors, and ethylene compressors. At the same time, SHENGU also received thank-you letters from its customers, who gave high praise to the company for its advanced technology, excellent quality, stable performance, and outstanding service. The product gas compressors and heat pump compressors for the 600,000 tons per year PDH plant in the Lummus process represent the first domestic production of such components, and the results have been very satisfactory. At the same time, we are deeply moved by the high level of attention your company has given to this project. SHENGU selected top-tier professionals who overcame the difficulties posed by the pandemic to ensure that the units were delivered on schedule, thus facilitating the smooth progress of the project. We are highly satisfied with SHENGU’s research capabilities, manufacturing skills, and service quality! Shenmu has proven with its capabilities and facts that our choice was absolutely correct! Compared to other similar devices, the “seven mosts” in the history of Taixing’s project development have enabled it to maintain a competitive edge in terms of technology selection, equipment choice, and management approaches. This project represents a rare case among similar facilities in the country, featuring the shortest construction period, the most efficient commissioning, and the most stable operation. The removal rate of non-methane total hydrocarbons for this project is 93%, which represents the highest environmental protection standard among similar facilities worldwide. In Project 98%, 98% of the key equipment features \"Chinese chips\"; its core component is the product gas compressor, which represents the first set of such devices to be manufactured domestically in this category, and it is at the leading level in China’s industry. The product gas compressor for the 600,000 tons per year propane dehydrogenation (PDH) plant, based on Lummus process technology, is a key core equipment for this project; it serves as a \"hub\" that connects the reactor above it with the product separation tower below, and is considered a technologically intensive type of major equipment. Previously, the product gas compressors used in domestic PDH units generally relied on imported equipment, resulting in long manufacturing cycles, high capital investment, and high maintenance costs later on. Shenmu provided it with a gas compression unit; the compressor features a configuration of \"motor + gearbox + high-pressure cylinder + low-pressure cylinder\", employing two-cylinder, three-stage compression, with 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 plant product gas, ending the reliance on foreign technology in such equipment in the country; its performance metrics are currently at the world’s leading level!
