| description | FIELD: oil and gas industry.SUBSTANCE: invention relates to method of preparing an aqueous pour point depressant dispersion composition for improving fluidity of crude oil at low temperatures. Method comprises steps of combining in an extruder ethylene vinyl acetate copolymer, a dispersing agent and water to form an aqueous dispersion of ethylene vinyl acetate copolymer which optionally can be mixed with an aqueous freezing point depressant.EFFECT: obtained pour point depressant reduces pour point of crude oil, exists in liquid state in a wide temperature range and demonstrates long-term resistance to creaming.10 cl, 1 dwg, 3 tbl, 10 ex
Изобретение относится к способу получения композиции водного понизителя температуры застывания в виде дисперсии для улучшения текучести сырой нефти при низких температурах. Способ включает стадии объединения в экструдере сополимера этиленвинилацетата, диспергатора и воды для получения водной дисперсии сополимера этиленвинилацетата, к которой, необязательно, может быть примешан водный понизитель температуры замерзания. Полученный понизитель температуры застывания обеспечивает уменьшение температуры застывания сырых нефтей, существует в состоянии жидкости в широком температурном диапазоне и демонстрирует долговременную устойчивость к сливкообразованию. 9 з.п. ф-лы, 1 ил., 3 табл., 10 пр. |
