大型氨厂改变原料路线调研

Survey of Change of Feedstock in Large Ammonia Plants

介绍大型氨厂原料路线的现状，提出了天然气、轻油、渣油型氨厂改变原料路线的方案及拓宽原料路线的具体措施，分析各种方案的利弊。在条件允许的前提下，应以煤为原料，采用德士古水煤浆气化技术。

The present status of feedstocks for large ammonia plants is briefly reviewed,and schemes forammonia plants based on natural gas,naphtha and residuum to change their feedstocks and concretemeasures for exploitation of substitute feedstocks are proposed,with analysis of the pros and cons ofthese schemes. When conditions permit,coal is to be chosen in change of feedstocks,and the Texacocoal-water slurry gasification process is to be employed.
