dc.description.abstractДосліджено й охарактеризовано важкі нафти з родовищ трьох областей України (Львівської, Сумської та Полтавської). Для зневоднення цих нафт розроблено та досліджено низку композицій із використанням деемульгаторів Dissolvan. Підтверджено синергічний ефект оксіетильованих та оксіпропільованих блок-кополімерів. Для зменшення в’язкості і підвищення ефективності зневоднення нафти розріджували важким газовим конденсатом. Для кожної досліджуваної нафти визначено оптимальні склади деемульгаторів. Чотирикомпозиції, які продемонстрували найвищу деемульгувальну здатність (90–94,5 %) під час роботи з досліджуваними нафтами, відібрано для подальших досліджень.
dc.description.abstractHeavy crude oils from the fields of three Ukrainian regions (Lviv, Sumy, and Poltava regions) have been studied and characterized. For dewatering these oils, a number of compositions using Dissolvan demulsifiers have been developed and investigated. The synergistic effect of oxyethylated and oxypropylated block polymers was confirmed. The crude oils were diluted with heavy gas condensate to reduce viscosity and increase dewatering efficiency. For each oil under study, the optimal compositions of demulsifiers were determined. Four compositions that showed the highest demulsifying ability (90–94.5 %) when working with the studied oils were selected for further research.
