几年来,化工企业的设计,在节约用地方面已做了多方面的努力。过去年产十万吨的合成氨厂要占用土地几十公顷乃至近百公顷,在通用设计中由于各方面的改进,大大压缩了工厂用地面积,现在用地只占过去的一半左右。在这已有的基础上,我们应当把节约用地的精种贯彻得更全面、更合理、更彻底,要使设计工作的各个环节紧密联系,专业间密切配合,为节约用地提供有利的条件。这里仅就氮肥厂在总平面布置中节约用 Over the past few years, the design of chemical companies has made many efforts in saving land. In the past, an annual output of 100,000 tons of synthetic ammonia plants occupied tens of hectares of land and nearly one hundred hectares. Due to various improvements in the universal design, the land area of ​​the factory was greatly reduced, and the land currently used accounts for only about half of the past. Based on this existing foundation, we should implement more comprehensive, more reasonable, and more thorough the intensive cultivation of land to be used for land conservation. We must closely link all aspects of the design work and closely cooperate with each other to provide favorable conditions for land conservation. Here only the nitrogen fertilizer plant is saved in the general layout
