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】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On December 22nd, the printed circuit board-type heat exchanger PCHE used in the regasification system of China’s first floating storage and regasification unit, FSRU, which was developed under the leadership of the 725th Research Institute of CSSC, completed full-condition operation tests as part of the second phase of the Zhuhai LNG expansion project. According to a responsible official from the 725th Research Institute of CSSC, an FSRU integrates various functions such as the reception, storage, transfer, and regasification of liquefied natural gas for transportation, and it also possesses the core functions of an LNG carrier. It is a key engineering device that connects offshore LNG production with onshore terminal consumption. The PCHE vaporizer, which serves as the vaporization function module, is the core component of an FSRU. Its primary role is to efficiently heat ultra-cold liquid natural gas at minus 162 degrees Celsius into gaseous form at normal temperature, enabling its stable transportation; its performance directly determines the operational stability, energy supply efficiency, and safety level of offshore gas stations. Previously, the core technologies for such equipment had been monopolized for a long time by a few foreign companies.
To overcome these challenges, Institute 725 relied on its technical expertise in marine materials, offshore engineering equipment, and special heat exchangers, and collaborated with companies such as CNOOC Gas & Power Group and Hudong-Zhonghua Shipbuilding to work on solutions. It succeeded in developing a series of key technologies, including those related to the design of high-efficiency heat transfer structures for microchannels. The PCHE vaporizer developed as a result set multiple domestic records in terms of structural dimensions and vaporization capacity. This full-condition operation test is the ultimate test of its practical application capability. During on-site testing, this gasifier was subjected to rigorous tests including multiple operating condition changes and long-duration continuous operation. Its overall performance showed that the gasification rate remained stable at 185 tons per hour; its volume was reduced by over 80% compared to traditional gasifiers. It met all the key requirements for the actual operation of FSRUs in terms of heat exchange efficiency, long-term operational stability, and resistance to corrosion in harsh marine environments, with some of its core performance indicators exceeding the design standards. Note: As a key project in the oil and gas infrastructure sector, the second phase of the Zhuhai LNG expansion project has an LNG processing capacity of 3.5 million tons per year. It is an important part of the natural gas production, supply, storage, and distribution system, and represents a vital measure for achieving the goals of carbon peak and carbon neutrality. It plays a significant role in optimizing the energy structure of the Guangdong-Hong Kong-Macao Greater Bay Area, as well as ensuring a stable supply of natural gas and energy security in the region.
