公用工程消耗 
public project consumption
- 讨论了求解换热网络最小公用工程消耗量的三种方法;
The three methods solving minimum utility consumption of optimal heat exchanger network were discussed. - 文中阐述了几种气相法生产聚乙烯装置的技术指标、公用工程消耗和综合能耗;
The technical specification comparison, utilities consumption and comprehensive energy consumption are described in this article; - 通过积分方法来计算随时间变化的公用工程消耗,所建立的数学模型因此比以往文献更加严格。
As utility consumptions are acquired by integral approach, the established mathematical model in this work is more rigorous than those reported in literatures.
