1) temperature and pressure exceeding

超温超压
1.
After urea plant and melamine system are put into joint operation,the melamine process ammonium carbonate recycled to urea increased water/carbon ratio of urea system,resulting in the decrease of urea conversion,load increases of medium and low pressure systems,as well as temperature and pressure exceeding of steam condensate system.
尿素装置和三聚氰胺系统联运后,三聚氰胺返回尿素的工艺碳铵液造成尿素系统水碳比增高,尿素转化率下降,中、低压系统负荷增加,蒸汽冷凝液系统超温超压。
2) high thermal

高温超压
3) LTOP

低温超压
5) low-temperature and-pressure ammonia synthesis

超低温低压
6) normal temperature hypertension

常温超高压
