采用平准化贴现产水成本法和最新的海水淡化经济评价软件 (DEEP1.1) ,对中东、阿拉伯海和北非地区核能海水淡化和常规能源海水淡化大量方案的经济竞争性进行了比较研究。结果表明 ,核能海水淡化具有较强的经济竞争性 ,其竞争性普遍存在于反渗透膜法、多效蒸馏法和多级闪蒸法等 3种淡化技术。淡化水成本由于所采用的淡化技术和水厂规模的不同 ,具有很大的差别 ,变化范围为 0 .5 2～ 1.93美元 .m- 3 ,反渗透膜法最便宜 ,多级闪蒸法最贵。影响其经济竞争性的敏感因素依次为 :贴现率、水厂规模、化石燃料价格、能源厂比投资和海水温度与海水总可溶固体物含量 ,与基准方案相比 ,水成本的变化率最高可达 2 2 .6 %。
Using the standardized water discounted water production cost method and the latest DEEP 1.1 seawater desalination evaluation software, a comparative study was conducted on the economic competitiveness of a large number of nuclear desalination and conventional energy seawater desalination schemes in the Middle East, Arabian Sea and North Africa. The results show that nuclear desalination of nuclear energy has strong economic competitiveness, and its competitiveness is commonly found in three kinds of desalination technologies such as reverse osmosis membrane method, multi-effect distillation method and multi-stage flash evaporation method. The cost of desalinated water varies greatly depending on the desalination technology used and the scale of the water plant, ranging from 0.52 to 1.93 USD/m3. The reverse osmosis membrane method is the cheapest, and the multi-stage flash evaporation method is the most expensive. expensive. The most sensitive factors affecting their economic competitiveness are: discount rate, water plant size, fossil fuel price, energy plant investment, seawater temperature and total dissolved solids content of seawater. Compared with the benchmark scheme, the rate of change of water cost is the highest. Up to 22.6%.
