介绍了国电赤峰化工公司“30·52”煤制尿素项目尿素生产系统采用传统的CO2汽提法生产工艺,尿素合成高压系统所需的甲铵液,是利用美国圣达因有限公司提供的高压甲铵泵输送的,由于低压循环吸收系统吸收的甲铵液的密度无法满足高压甲铵泵所需的密度,致使高压甲铵泵出口压力不能满足系统需要,导致高压系统因缺少反应液而引起系统运行波动,为此进行了增加甲铵升压泵的技术改造。
Introduced the State Power Chifeng Chemical Company “3052 ” coal urea project urea production system using the traditional CO2 stripping production process, urea synthesis of high-pressure system required ammonium solution, is the use of the United States St. Darwin Co., Ltd. to provide Of the high-pressure ammonium pump delivery, due to low-pressure cycle absorption system to absorb the density of the ammonia solution can not meet the high-pressure ammonium pump required density, resulting in high-pressure ammonium pump outlet pressure can not meet the system needs, resulting in high pressure system due to the lack of reaction liquid Which led to fluctuations in system operation, for which an increase of ammonia booster pump technological transformation.
