中型尿素厂技术改造建议

Proposals to revamping of middle urea plants

国内绝大多数采用传统水溶液全循环法生产尿素的中型厂，物耗高、技术指标落后，缺乏市场竞争力．本文基议中型尿素厂实施技改的重点是扩能和降耗相结合，即扩大生产能力使之形成经济规模和采用先进的技术进行改造．

Most domestic middle urea plants with traditional total solution recycle process incur the disadvantages of higher consumptions, backward technical figuresand,tberefore, lack of market competitiveness. The papersuggests that the important point of revamping of middleurea plants should be the combination of capacity expansionand consumption lowering,i. e. to extend production capacity makes up an economical scale and adopt advancedtechnology in Carrying out technical revamping.
