HYSYS的FRSU系统性能优化分析
本文着眼于FSRU再气化系统中常用的气化器——中间介质气化器（IFV）。在我国四大海域不同的地理气候条件下，对IFV中气化器不同的布置方式，即整体式与分开式，结合不同的中间介质利用HYSYS软件进行过程模拟，模拟结果表明：在渤海海域以丙烷为中间介质的整体式IFV综合性能最佳。其次，本文在该基础上，针对具体的气化流程，从调温器流程选择、海洋工作状况防晃动、参数优化以及换热面积分析这四个不同的角度对FSRU再气化模块提出进一步的优化方案，为我国在该领域的发展提供技术支持。

Abstract In recent years, with our country and the world changed the development pattern, oil, coal energy gradually growth slowly, and the growing demand for clean energy promote the fast growth of natural gas consumption。 In our country especially coastal areas,Natural gas resources is pinch and most rely on imported which makes the LNG floating storage and regasification unit(FSRU) attract people's attention。 However,the technology was monopolized by foreign at present, it is the key for the related staff to realize the localization and optimization。This paper focuses on the common heat exchanger in the FSRU regasification system - the intermediate fluid vaporizer(IFV)。Under the four sea areas of different geographical and climate conditions in our country, different arrangement of the vaporizer in IFV, namely the integral and separate type, are taken process simulation by HYSYS combined with different intermediates。And then based on these,the paper also put forward some further optimization schemes for specific gasification process from four different angels which are thermostat process selection, ocean working condition to prevent shaking, parameter optimization and the analysis of the heat transfer area,which can provide technical support in this aspects of the development of our country。
