According to online reports, at 2:36 a.m. on April 30, the 600,000 tons per year LNG production project in Tai’an, Shandong, operated by China National Petroleum Corporation’s Kunlun Energy and undertaken through EPC contracting by Beijing Global Company, successfully produced qualified LNG products, marking the successful commissioning of the project.
The Tai’an 600,000-ton LNG (liquefied natural gas) equipment localization project is China’s first large-scale natural gas liquefaction project built using domestic technology and equipment. It represents the first major initiative in China for the localization of LNG processing technologies and key equipment. Additionally, it is the only inland provincial-level LNG storage facility in Shandong Province, and it plays a crucial role in enhancing gas storage capacity and the system’s ability to regulate supply during peak periods, thereby ensuring a safe and stable supply of gas across the province.
The project has a daily natural gas processing capacity of 2.6 million cubic meters, and can supply 600,000 tons of LNG (liquefied natural gas) per year. The process technology utilizes the dual-cycle mixed refrigerant (DMR) liquefaction technology developed by Huanqiu Company, thereby achieving serialization and standardization in natural gas purification technology, liquefaction technology, and storage and transportation technology. During the project implementation, a total of 46 **patents** were obtained, 3 **standards** were established, and over 50 proprietary technologies and construction methods were developed.
It is reported that during the project construction, Huanqiu Company made full use of the advantages provided by its **Energy LNG R&D Center to lead domestic material and equipment manufacturing enterprises in joint technical efforts. As a result, the complete localization of key equipment such as refrigerant compressors and drive motors, low-temperature BOG compressors, cryogenic tanks, DCS systems, low-temperature valves, and high-pressure frequency converters was achieved. This reduced the costs associated with purchasing project equipment significantly, and the technical specifications of these devices reached international advanced levels. It is regarded by the industry as a major breakthrough in the development of China’s LNG equipment industry. The successful implementation of this project also holds significant strategic importance for Huanqiu Company in mastering large and medium-scale natural gas liquefaction technologies and developing its own proprietary natural gas technologies.
Guess how big this storage tank is
Another major step forward has been taken with all equipment now being domestically produced
Liquefaction unit – why two cold boxes?
