1、  概述：

Introduction

    合成氨是氮肥工业的基本原料，氨是由氮和氢两种气体在高温、高压和催化剂存在条件下化合而成的。根据制取氮和氢两种原料的方法不同，分为气体原料法、固体原料法和液体原料法三种。

尿素是高效氮肥，尿素的生产是用合成氨装置的氨和二氧化碳为原料，在高压和高温下合成的。

Ammonia is one of basic raw material for nitrogen fertilizer industry. Ammonia is produced by nitrogen and hydrogen at high temperature and pressure with catalyst. The process of ammonia is as gas raw material process, solid raw material process and liquid raw material process because of the method producing the nitrogen and hydrogen.Urea is high efficiency nitrogen fertilizer. Urea is produced by ammonia and CO2 at high temperature and pressure.
