摘要
以当今节能型尿素生产新技术改造溶液循环法的中小型尿素厂,从技术的角度是可行的。为了节约投资,分析了老设备利用率的问题。认为实施这种改造经济上不是很合算。
Solely from the technical view point it is feasible that the existing small or middle urea plants using solution recycle process may be retrofitted with prevailing low energy processes of new technologies. For saving on investment, it is not so much nevertheless as an economical measure to be in effect because of the lowering of usage of existing equipment.
