摘要
用炼油废硫酸与天然石灰石合成石膏,已取得工业化的经验.其工艺简单,操作方便.合成石膏应用于水泥等建材制造工业,与天然石膏有一致的性能.实践证明,该方法是处理炼油厂废硫酸较好的方法之一.
The production of gypsum with refinery spent sulfuric acid and limestone has been successfully commercialized. The gypsum thus produced can be used for cement production as a substitute for plaster stone. This process is simple and economical. Commercial practice has confirmed that it is a feasible route of spent acid diposal in refinery.
