STUDY OF THE EFFECTIVENESS OF DIEMULSIFIERS UNDER STATIC CONDITIONS
Abstract
<strong>To demonstrate the high efficiency of the demulsifier, it must dissolve only in the continuous oil phase, must be sufficiently stable for storage or use, cost-effective and be able to also efficiently process crude oils of more than one type. Good results on desalination and dehydration of typical oil were obtained when using DE-5 in an amount of 30-40 g/t. With a salt content of 505 mg/l, oil was able to desalinate oil by 91.1%, with a salt content of 775 and 1438 mg/l only by 57.7 and 69.3%. An increase in the consumption of the emulsifier above 40 g/t does not significantly reduce the residual salt content, leaving it sufficiently high (35-51 mg/l). The use of the emulsifier makes it possible to obtain oil with a salt content of 14 mg/l with the consumption of DE-5 in an amount of 20 g / t and 10% of washing water.</strong>
