- 摘要:
- 为合理确定LNG工厂厂址，优化工厂总图设计，减少工厂对外部设施的影响，使总图设计更加合理、安全、实用、经济、且节约用地，有必要明确影响厂址选择总图设计的影响因素。通过分析LNG工厂一般构成、工艺流程与天然气处理厂对比以及国家地方政策及法规，得出选址要点有：LNG储罐溢流、蒸汽云扩散、储罐区池火、火炬热辐射和LNG槽车运输因素。通过分析总图设计规范的使用，提出影响总平面布置的因素有工艺流程、LNG储罐形式、围堰尺寸、防火、防噪、环入式装车形式和倒入式装车形式。从竖向布置、管网综合布置方面论证了总图设计要点，使总图设计更优化合理，安全可靠。

In order to select liquefied natural gas (LNG) plant site reasonably, optimize plant plot plan design, reduce effect of plant facilities on external facilities and surroundings and make plot plan design be more reasonable, safe, practical and economic, it is necessary to make clear those factors affecting plant site selection in plot plan design. Conducted is analysis on general structure and technological process of LNG plant, compared are some characteristics of LNG plant with natural gas treatment plant and conducted is analysis on relative requirements specified in national or local policies and laws and regulations followed in LNG plant plot plan design and listed are such considerations in plant site selection design as LNG storage tank overflow, vapor cloud diffusion, storage tank area and flare thermal radiation range around LNG plant and transportation conditions. In addition, the following design essentials shall be considered in plot plan design: technological process, LNG tank type, cofferdam size, fire and noise prevention and tank loading type, etc.
