据世界天然气网站8月17日消息 一项新的示范试验发现，新一代浮式储存再气化装置（FSRU）在最大额定再气化装置流量下的燃油消耗量和二氧化碳排放量可比传统的现有FSRU减少50%。
日本航运巨头三井轮船公司（MOL）和韩国造船厂大宇造船和海洋工程公司（DSME）已在DSME的Okpo造船厂对FSRU的低温动力再气化系统进行了演示试验。
FSRU的作用是通过热交换将-160°C液化天然气再气化。在过去，液化天然气的冷能并未用于FSRU，而是被释放。
两家单位解释称，通过安装低温驱动的再气化系统，这种冷能量将被转移到另一种加热介质，产生的蒸汽将被输送到涡轮机发电，从而降低FSRU的燃料消耗和二氧化碳排放。
该系统的小型版本是在DSME的研发场所建造，该系统中使用的涡轮发电机由三菱重工船舶机械设备有限公司专门为CPR系统设计和建造。
MOL和DSME从去年2月起就一直致力于该项目，通过这项测试，验证了该系统能够成功地发电至其额定容量。
据了解，低温动力再气化系统现已准备好在实际FSRU项目中实施。
将具有较低CO2排放率的燃油效率FSRU引入市场是MOL为实现MOL集团环境愿景2.1而采取的举措之一。该公司承诺努力到2050年实现温室气体净零排放。

Next-gen FSRU system cuts fuel consumption, CO2 emissions by 50 pct
Fuel consumption and CO2 emissions of new generation floating storage regasification units (FSRUs) can be reduced by 50 per cent at maximum rated regas flow rate compared to conventional existing FSRUs, a new demonstration test found.
Japanese shipping major Mitsui O.S.K. Lines (MOL) and South Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME) have carried out the demonstration test of the “Cryo-Powered Regas” system for FSRU at DSME’s Okpo shipyard.
The role of an FSRU is to regasify -160°C liquified natural gas (LNG) through heat exchange. In the past, LNG’s cold energy had not been utilized in FSRUs and was released.
By installing the Cryo-Powered Regas system, such cold energy will be transferred to another heating medium, and the generated steam will be sent to a turbine to generate electricity, which results in reducing FSRU’s fuel consumption and CO2 emissions, the duo explained.
A small-scale version of the system was built in DSME’s R&D premises. The turbine generator used in this system was designed and constructed by Mitsubishi Heavy Industries Marine Machinery & Equipment Co., Ltd. specifically for the CPR System.
Through this test, MOL and DSME — which have been working align="justify"> As informed, the Cryo-Powered Regas system is now ready for implementation in actual FSRU projects.
Introducing fuel-efficient FSRUs with lower CO2 emission rates to the market is one of the initiatives that MOL is pursuing towards the achievement of MOL Group Environmental Vision 2.1. The company committed to make effort to achieve net zero GHG emissions by 2050.
