用先进适用技术改造传统法尿素装置

对我国传统法尿素装置进行了技改论证和技改策略与原则讨论，以流程模拟计算数据为基础，指出传统法尿素装置合成效率低是造成经济指标落后的原因，提出了4种技改方案。

Reforming the Traditional Method Urea Plant by Advanced and Suitable Technology

Proof was made for technical reformation in the traditional method urea plant of China, and discussion was also made for strategy and principle of the technical reformation, having taken the analog calculation data of process as the basis, it was indicated that the low synthetic conversion rate of the traditional method urea plant was the reason making the economic indexes behindhand, four schemes for technical reformation were presented.
