Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are important ω -3 polyunsaturated fatty acids. Their physiological effects on humans are not exactly the same; therefore, the production of products with high-purity EPA or DHA monomers is significant. In this work, EPA ethyl ester (EPA-EE) and DHA ethyl ester (DHA-EE) were first separated using HPLC with poly(styrene-co-divinylbenzene) (PS/DVB) as the stationary phase. The effects of the mobile phase, PS/DVB particle diameter, and column temperature were systematically evaluated. The results showed that methanol is a suitable mobile phase, having a resolution of 2.75. By comparing resolutions, a PS/DVB particle diameter of 10 μ m was chosen; however, when the pressure drop of PS/DVB is considered, PS/DVB with a particle diameter of 20 μ m is more favorable for large-scale preparations. A column temperature of 40℃ was found to be the most feasible for maintaining efficient separation. Second, eight semi-preparative columns (150 mm×10 mm) of PS/DVB polymer were prepared for the simulated moving bed (SMB) chromatography; the homogeneity of these columns was perfect, with a relative total column porosity error of less than 1%. Finally, an EPA-EE and DHA-EE mixture was separated using the SMB chromatography, and the contents of the extract and the raffinate were determined using GC-FID. The effects of the flow rate of Zone Ⅱ and Zone Ⅲ, the flow rate of the feed, and the feed concentration were investigated. Under optimal conditions, EPA-EE and DHA-EE with favorable purities of 91.6% and 93.6%, respectively, were achievable. The recovery of the EPA-EE was 97.0% and the recovery of the DHA-EE was 91.6%. The productivity and solvent requirements were 5.97 g/(L\5h) and 1.52 L/g, respectively. Therefore, SMB chromatography is an attractive technology for the production of high-value products.
