摘要
介绍了分馏塔出现结盐现象的原因和给生产带来的不利影响。详细分析了结盐过程,介绍了结盐处理的2种方案,并给出在线水洗方案的具体步骤。通过对洗塔前后操作参数及产品分析,表明水洗后分流系统主要指标正常,汽柴油产品分布合理,质量合格。最后提出了几点预防分馏塔结盐的措施。
The causes of salt deposition in the fractionator and its adverse impact on production are introduced in this paper. The process of salt deposition is analyzed in detail. Two solutions for salt deposition are proposed. The procedure of the on-line water washing process is given. The main indicators of fractionation system after water-washing are proper and the product distribution is reasonable and qualified by analyzing the operating parameters and products. Some effective methods are put forward to prevent salt deposition in the fractionator as well.
