PILOT STUDY ON HYDROCYCLONE-COALESCENCE METHOD FOR OIL AND SOLID REMOVAL FROM ACID WATER

Abstract

Abstract: 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.

Key words: sour water, hydrocyclone-coalescence, oil and solid removal, stripping
