摘要

Abstract

A novel hydrocyclone with guide vanes

named as axial hydrocyclone (AHC)

is designed to tackle the problem of oil-water separation faced by most mature oilfields. Optimal design of the AHC is carried out by using numerical methods. The effects of guide vanes

cone angle

tapered angle and overflow pipe on the oil-water separation are discussed in this paper. The results show that a double swirling flow is generated in the tapered section where oil-water separation occurs. Both the cylindrical and the tapered section have important influences on AHC performance. On the basis of single factor results

response surface methodology is employed to optimize the AHC design. The experimental results indicate that the novel AHC has an excellent performance for the oil-water separation.
