Abstract:

Conclusions 1 Tested block copolymers have a deemulsification activity and can be recommended for deemulsification and desalting of crudes. 2 Most deemulsifying activity is possessed by block copolymers, obtained on the basis of propyleneglycol, in which the propyleneglycol part of the molecule was condensed from 60 ethylene oxide and the molecular weight is 1400-1800 a further increase in percentage of ethylene oxide reduces the effectiveness of the block copolymer. The ratio of molecular weight of oxyethyl groups to ocypropylene groups equals 3 2. For ethylenediamine base block copolymers, having high deemulsification activity, the ratio of the hydrophobic part of molecule The polypropyleneglycol part of the molecule is called conditionally hydrophobic, although it possesses certain hydrophilic properties to hydrophilic is 1.5. 3 Most effective with respect to the deemulsification effect block copolymers are not inferior to the best imported samples.
