芳烃抽提后抽余油的开发研究

Study on the Development of the Remainders after the Aromatic Extraction from Heavy Duty Diesel Oil

研究了对小批量芳烃抽提后的抽余油，用二榨滤液稀释后两次冷冻脱蜡工艺．该工艺不需深度冷冻条件。

The remainder affer the aromatic extraction from heavy duty diesel oil can be deluted with filtrate of second pressing oil and then chilled twice for dewacing. The method does not require strong chilling or the process of nenewing solvent.
