深圳液化石油气低温常压储存工程可行性分析

Analysis on the Feasibility of Shenzhen LPG Storage Project.

深圳液化石油气（ＬＰＧ）低温常压储存工程拟建４×１０＾４ｔ丙烷、丁烷储罐各一座，５×１０＾４ｔ低温常压ＬＰＧ泊位一座，５０００ｔ常温高压ＬＰＧ泊位两座，总投资１．１亿美元。该工程系中外合资项目，现已开始建设，预计１９９７年底建成。介绍了该项工程的规划，工艺技术方案、经济分析、环境评价，经过分析比较，选用直接冷却式氏温常压储存加工工艺。这种工艺技术在相同储存温度下较间接冷却工艺流程简单。

Shenzhen LPG Storage Project, having an estimated investment of 110 million US dollars, consists of two 4×104t tanks (one for propane and one for butane), a 5×104t berth for low temperature atmospheric tanks, and two 5×1031 berths for high pressure tanks. This project involving Chinese and foreign investments is now under construction and will be completed by the end of 1997. Introduced in this paper are the project planning, process program, economic analysis, as well as environmental evaluation. Through analysis and comparison, the process of direct refrigerating, low temperature and atmospheric storage is selected. Comparing with indirect refrigerating mode, this process is featured by simpler flow process and lower operation and management costs. Double containment metallic tanks with suspended roofs are adopted. Also analyzed is the seismic impact on tanks. Having such characteristics as advanced technology, simple equipment, low investment and short construction period, this project will improve the energy stockpiling capacity and create better investing environment for Guangdong Province.
