Дослідження нейоногенних деемульгаторів різної будови на штучних нафтових емульсіях
The experimental results concerning demulsified ability of block copolymers of ethylene and propylene oxides wich may be used as demulsifiers for oil emulsions have been represented. The dependence of their efficiency on the content of oxyethylene and oxypropylene groups in the molecule has been determined. The dependence of their degree of dehydration on the temperature and emulsion composition has been determined.
