This paper presents a polynomial model for the characteristic curves of the synthesis gas compressor of Kellogg-type ammonia plants and a regression model for vapor-liquid equilibria in ammonia separation as well as for loop pressure drop based on plant data .

文中建立了Kellogg型氨厂合成气压缩机特性曲线的多项式模型及氨 分离过程 汽 液平衡与回路压力降回归模型。

In addition there is no vapor-liquid interface when using a wash column for ice crystal separation . Thus freeze concentrated products also maintain original flavors .

此外，用洗床 分离冰晶时不会 形成 气液分界面，因此，冷冻浓缩后仍保持原有香味。
