可再生能源电解水制氢-低温低压合成氨万吨级工业示范流程设计
Process design of 10000 t industrial demonstration of hydrogen production from renewable energy electrolytic water-low temperature and low pressure ammonia synthesis
摘要
Abstract
Hydrogen energy is one of the most promising clean energy sources.Green hydrogen production can be achieved by electrolyzing water from renewable energy sources,but the efficient storage and transportation conditions of hydrogen are difficult.Ammonia is an efficient hydrogen storage material,but the high temperature and high pressure reaction conditions required for ammonia synthesis lead to high energy consumption.Therefore,the process development of hydrogen production from renewable energy electrolytic water-low temperature and low pressure ammonia synthesis is of great significance for green transformation of energy and low-carbon development of company.Based on Aspen Plus process simulation software,this study designed and developed a process of hydrogen production from renewable energy electrolytic water-low temperature and low pressure ammonia synthesis.Combined with the production conditions of synthetic ammonia industrial demonstration enterprise,a 10000 t synthetic ammonia demonstration production process was reasonably designed.The photovoltaic power generation combined with network electricity was used to supply energy for the alkaline electrolytic water to produce hydrogen,and 1000 m3/h(standard condition)hydrogen with the purity of 99.999％was produced at 85℃ and 1.6 MPa.In order to meet the demand for 10000 t synthetic ammonia,further combined with the existing nitrogen and hydrogen-nitrogen mixture of the industrial demonstration enterprises,the reaction of ammonia synthesis was carried out at 400℃ and 7 MPa,and the liquid ammonia product with a purity of 99.9％was obtained by ammonia cold separation.In addition,the high energy consumption synthetic ammonia process is designed with four heat exchangers to save energy.This study can provide a reference for the industrial demonstration of low temperature and low pressure ammonia synthesis with hydrogen production from renewable energy electrolytic water.关键词
