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 Great Development 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 modular submerged combustion vaporizer (SCV) unit, which is a key component of offshore gas stations and represents the first of its kind in China to utilize a floating storage and regasification unit (FSRU), was delivered. It was developed independently by ZhongSheng HighTech, a company under Nanjing ZhongSheng Technology Group. It is also the first marine SCV modular unit in the country to be put into engineering use in marine environments. The modular submersion combustion gasifier unit delivered this time not only retains the advantages of land-based submersion combustion gasifiers, such as fast startup and high gasification capacity, but has also been comprehensively upgraded for marine use: its heat transfer efficiency is no less than 98%, and the nitrogen oxide emission levels are below the environmental standards set by international maritime conventions. Based on practical application scenarios, this FSRU vessel can carry 3 units of equipment, and its daily production capacity is sufficient to meet the gas demand of 5,000 households for one year. Within the same floor space, its vaporization capacity is superior to that of traditional seawater-heated vaporization units, providing a solid foundation for the efficient and stable operation of offshore gas stations. In simple terms, this huge device is the ‘super heater’ for offshore gas station ships. The core function of the SCV unit is to efficiently heat and vaporize the liquid natural gas, stored on board at around -160°C, into gaseous natural gas at normal temperature, which is then transported to land via pipelines. Currently, LNG regasification units in the industry are mainly divided into three types: intermediate medium-type gasifiers, open-type gasifiers, and submerged combustion gasifiers. Open-type gasifiers, due to their vertically installed open structure, are susceptible to the effects of sea waves and are not suitable for use on ships ； The intermediate medium gasifier was the conventional technology previously used in the industry for converting land-based systems to ship-based ones; Zhongsheng Gaoke also achieved a breakthrough in making this technology domestically available in 2015. Changing it from land use to marine use is as difficult as trying to build a stove to cook on a swaying ‘swing’. The stove becomes unusable with the slightest mistake. Moreover, it is necessary to automatically match and adjust the equipment’s operating parameters based on the gas demand of downstream users, which requires a very high level of intelligence. To address these challenges, Zhongsheng High-Tech Company and Zhongsheng Research Institute assembled a team of technical experts to work on research and development. After numerous rounds of effort, they upgraded the automatic control system of the equipment; by using AI algorithms, functions such as one-click start/stop, fault and accident alerts, real-time monitoring of performance parameters, and intelligent automatic load adjustment were implemented, eliminating the need for manual operation or supervision. The team also proposed a lightweight design concept for modularizing the vaporizer, keeping the total weight of the equipment below 100 tons – which is more than 50% lighter than the modules used by Landwind. This not only meets the strict requirements imposed by ships on the structural dimensions of such equipment, but also allows for significant savings in shipboard space. It is understood that Zhongsheng Technology Group plans to begin mass production of this modular unit in the future; in addition to being used in FSRUs, it can also be applied to other LNG carriers. At the same time, the group plans to introduce this domestic technology to regions with high LNG demand such as Europe, thereby boosting the process of making China’s core offshore engineering equipment domestically produced and available on the international market.
