NH_3-CO_2-H_2O三元体系相图查图方法的改进及其在氮肥生产中的应用

Improving of the Reading Technique of NH_3-CO_2-H_2O Terary System Phase-Diagram and Application in Nitrogenous Fertilizer Production

首先对以氨碳比和水碳比表示溶液组成的NH_3-CO_2-H_2O三元体系,在查阅其直角等腰三角形相图时不是采用传统的查图方法,而是借鉴了直角坐标的查图方法,使查图过程变得简单、准确和直观。然后,简单地探讨了新的查图方法在尿素生产中的应用。

First, the article uses the reading technique of the right angled coordinate for reference to replace the traditional reading way on the right angled isoceles triangle phase-chart in NH_3-CO_2-H_2O ternary system of using molecule-rate of ammonia and carbon dioxide, water and carbon dioxide to show the solution compose. The new way makes the reading process more simple and veracious. Second, the article simply discuss the application of the new reading way in urea producing.
