日产千吨大型天然气一步法尿素装置国产化预设计简介（上）

Brief introduction to preliminary designing of uationalized manufacturing 1000t/d large natural gas-based urea plant containing one-step process

我国天然气一步法尿素生产技术已居世界领先水平，且已具备大型装置国产化条件．日产千吨尿素装置设计表明，吨氨天然气耗８５０Ｎｍ３，能耗３０．５８ＧＪ（７．３１Ｇｅａｌ），年万吨尿素投资约２０００万元．

Natural gas-based urea production techndogy with one-step process in our country is in the lead in the world. There have been necessary requisites for large scale plant with this process to be manufactured natively. The design of 1000t/d urea plant shows figures: natural gas consumption per ton ammonia 850 Nm3, energy consumption 30. 58 GJ(7. 31Gcal), and the capital investment per 10,000 ton urea 20 million RMB.
