综合利用化肥厂CO_2的方法

An Approach to Utilize CO_2 from Fertilizer Plant

以石脑油为原料的合成氨厂,将过量的 CO_2通过冷却、除水净化后,可生产食品级的液体 CO_2。所需设备是县级小化肥厂更换下来的闲置高压容器,既做到了投资低,又减少了气体 CO_2的排放,对改善局部大气环境起了一定积极作用,也提高了企业的经济效益。

For fertilizer plants using naphtha as feedstock,food-grade liquid CO_2 and be produced by cooling water removal and purification of excess CO_2.The equipments required for the system are the spared high pressure vessels suppl- ied from small fertilizer plant.Therefore,the economic benefits of enterprise will also be improved.The discharge of CO_2 gas can be reduced and local atmospheric environment will be improved.
