Type: article
Abstract: Purification of waste formation waters from oil by simultaneous destruction of reverse and direct emulsions is a serious environmental and technological problem in the conditions of primary preparation of oil (PPO). The authors conducted targeted laboratory studies on the purification of waste formation waters from oil under PPO conditions of Kazpetrolgroup LLP in the Republic of Kazakhstan. The article presents the results of a comparison of the main characteristics of the reagents taking into account the re¬quirements for demulsifiers and establishes significant advantages of nanodemulsifiers IKHLAS-1, 2, 3 compared to the basic demulsifier Easy d 01. In the case of Easy d01, a clear pattern of brown color of an environmentally hazardous, hard destructible water in oil emulsion (HDWOE) was discovered for the first time. Nanodemulsifiers IKHLAS-1, 2, 3, on the contrary, have inhibitory properties relative to HDWOE. The results of bottle tests also established the high efficiency of IKHLAS-1, 2, 3 in terms of residual concentrations of water, salt, mechanical impurities in oil, as well as the concentration of oil in water
