Energy-saving process for deacidification and deodorization in oil production

The invention belongs to the technical field of oil production, and particularly discloses an energy-saving process for deacidification and deodorization in oil production, which comprises the following steps: carrying out primary steam injection treatment on mixed gas from a deodorization tower, carrying out primary vacuum condensation, carrying out secondary steam injection on non-condensable substances after primary vacuum condensation, carrying out secondary vacuum condensation, and performing sequential deodorization and decolorization of non-condensable substances after secondary vacuum condensation. According to the invention, tap water is replaced by low-temperature cleaning water, so that the water consumption is reduced, and the optimal working temperature of the water ring vacuum pump is ensured to be 5-15 DEG C. 本发明属于制油技术领域，具体公开一种在制油中脱酸脱臭的节能工艺，包括将来自脱臭塔的混合气体进行一级蒸汽喷射处理后再进行一级真空冷凝，一级真空冷凝以后将不凝物质进行二级蒸汽喷射以后再进行二级真空冷凝，二级真空冷凝以后将不凝物质依次进行脱臭和脱色处理，本发明通过用低温清洗水代替自来水，节省了水耗，且保证了水环真空泵的最佳工作温度5~15℃。
