"我们我们这空冷前是连续注水，高换考虑换热温度采取间歇注水" " "都空冷前和高高换前都是连续注，但高换前注水量是根据采样分析调整注水量" "空冷前连续注水，每周固定时间切换注水点至高换前几个小时。" "加氢注水建议连续注水，原料性质的改变、工况、天气操作等条件一旦出现变化、结盐的温度和位置就会改变、一旦铵盐形成、处理起来就不知道这点水的问题啦"

都空冷前和高换前都是连续注，但高换前注水量是根据采样分析调整注水量，如果原料分析变化不大注水量变化也不大，主要是看原料含氮量的高低

空冷前连续注水，每周固定时间切换注水点至高换前几个小时。

加氢注水建议连续注水，原料性质的改变，工况、天气操作等条件一旦出现变化，结盐的温度和位置就会改变，一旦铵盐形成，处理起来就不知道这点水的问题啦
