采用氨酸法工艺生产复混（合）肥，需要大量叫（H2SO4）约60％的稀硫酸。原用搪玻璃反应釜间歇式将叫（H2SO4）98％的浓硫酸稀释成所需稀硫酸，存在诸多问题。介绍用石墨冷却器连续式将浓硫酸稀释的工艺流程、工艺指标、节能降耗效果，满足了氨酸法生产对稀硫酸的需要。
採用氨痠法工藝生產複混（閤）肥，需要大量叫（H2SO4）約60％的稀硫痠。原用搪玻璃反應釜間歇式將叫（H2SO4）98％的濃硫痠稀釋成所需稀硫痠，存在諸多問題。介紹用石墨冷卻器連續式將濃硫痠稀釋的工藝流程、工藝指標、節能降耗效果，滿足瞭氨痠法生產對稀硫痠的需要。

The a great quantity di!ute sulfuric acid with w（H2SO4） 60% is required in compound fertilizer production by ammonia-acid method. There are many problems in dilution of concentrated sulfuric acid with w（H2SO4）98% by batch-type glass lining reactor, The process, process indicators, the energy saving effect of diluting concentrated sulfuric acid by continuous system graphite cooler are introduced, it can meet the requirement of compound fertilizer production by ammonia-acid method.
