我国小氮肥工业40年来,从无到有,从小到大,无论是能力和产量,还是技术水平和管理水平,都有了十分巨大的变化,小氮肥已成为我国化肥工业的一支重要力量。1997年,全国小合成氨产量已达1704万吨,占全国合成氨总产量的57％:小尿素产量677万吨,占全国尿素总产量的30％;全国小氮肥的生产能耗已与中型氮肥厂相
In the past 40 years, China’s small nitrogenous fertilizer industry has grown from scratch and has grown from small to large. Both in terms of capacity and output, as well as technical level and management level, there have been tremendous changes. Small nitrogen fertilizers have become an important force in China’s chemical fertilizer industry. In 1997, the output of small synthetic ammonia in China reached 17.04 million tons, accounting for 57% of the total output of synthetic ammonia in the country. The output of small urea was 6.77 million tons, which accounted for 30% of the total urea output in the country; the production energy consumption of small nitrogen fertilizer in China was already comparable to that of medium-sized nitrogen fertilizer plants. phase
