天然气水合物开采耦合重整制氢系统的能效和经济性评价
Energy efficiency and economic evaluation of coupled natural gas hydrate exploitation and reforming hydrogen production system
摘要
Abstract
To improve the energy efficiency of a coupled natural gas hydrate exploitation and reforming hydrogen production system,process design and modeling were conducted,and models for energy efficiency assessment and economic analysis were established.Focusing on the selection between fuel heating or electric reforming in the reforming process,whether offshore wind power is integrated in electric reforming,and the selection between membrane separation or amine scrubbing in H2 separation,the exergy efficiency ratio and annual total cost of different technical schemes were compared.The results show that System C,with electric reforming without offshore wind power integration and membrane separation,has the highest exergy efficiency ratio(2.25).System B,with fuel heating reforming and membrane separation,has the lowest annual total cost(5803.91 × 106 CNY/a).System F,which integrates offshore wind power and uses amine scrubbing for separation,has the highest annual total cost(5862.09 × 106 CNY/a),only about 1.0%higher than the most economically efficient System B,but with higher energy efficiency.This indicates that the application of membrane separation and offshore wind power on hydrate exploitation platforms has significant potential in both energy efficiency and economy.关键词
