摘　　要：酸性水的除油脱固预处理是后续汽提工艺稳定及装置安全运行的重要保障,随着酸性水中乳化油和细微固体悬浮物杂质含量的提高,当前预处理系统普遍存在预处理效果不佳的问题。以酸性水进入汽提塔前预处理流程为基础,提出了一种旋流-聚结组合的除油脱固技术并开展了中试试验,该技术对酸性水除油率平均可达98.78%,悬浮物去除率平均可达89.87%,同时,试验设备可降低酸性水的化学需氧量。With the increase of the content of emulsified oil and fine solid suspensions in acid water,the pretreatment for oil and solid removal from sour water is an important guarantee for the stability of the subsequent stripping process and the safe operation of the unit,but the current pretreatment system generally has the problem of poor performance.Based on the pretreatment process of acid water before entering stripper,a new technology for oil and solid removal was put forward using hydrocyclone-coalescence combination,and a pilot test was carried out.The results showed that the average oil removal rate of acid water was 98.78%,the average removal rate of suspended solids could reach 89.87%,and the test equipment could reduce COD in sour water.
