宁晋县化肥厂脱碳系统碳丙稀液一直采用间断式补加方式 ,即稀液一般一个班分 1～ 2次向系统补加 ,使循环溶剂中水含量一直不稳定。为此 ,笔者从脱碳系统的闪蒸气引出一分支做动力源来完成稀液的连续式补加。以碳丙一级回收工艺为例 ,工艺流程见图 1。图 1 新鲜软水加入洗涤
Ningjin County Chemical Fertilizer Plant decarburization system carbon-acrylic liquid has been discontinuous addition, that is, a general sub-dilute liquid 1 to 2 times to the system added to the circulating solvent water content has been unstable. For this reason, I derive a branch from the flash vapor of the decarburization system as a power source to complete the continuous addition of dilute solution. A carbon-carbon recovery process, for example, the process shown in Figure 1. Figure 1 Fresh water added to wash
