四种不同冬化脱蜡工艺的比较及优缺点

Comparison of four different winterization-dewaxing processes and their advantages and disadvantages

为了找到最合适的冬化脱蜡工艺,对四种不同的冬化脱蜡工艺(中和碱炼+脱色+脱臭+脱蜡工艺,中和碱炼+脱蜡+罐区储存+脱色+脱臭工艺,中和碱炼+脱色+脱蜡+脱臭工艺,中和碱炼+脱蜡+脱色+脱臭工艺)进行了生产实践,并对生产效果进行了对比分析。结果表明,与其他三种冬化脱蜡工艺相比,中和碱炼+脱蜡+脱色+脱臭工艺电耗、蒸汽消耗适中,白土消耗可控,产品质量稳定,是最佳的冬化脱蜡工艺。

In order to find the most suitable winterization-dewaxing process, four different winterization-dewaxing processes(neutralization + bleaching + deodorization + dewaxing, neutralization + dewaxing + tank storage + bleaching + deodorization, neutralization + bleaching + dewaxing + deodorization, neutralization + dewaxing + bleaching + deodorization) were carried out in production line, and the production effects were compared and analyzed. The results showed that compared with the other three winterization-dewaxing processes, the neutralization + dewaxing + bleaching + deodorization process had moderate power consumption, steam consumption, controllable clay consumption, and stable product quality. The neutralization + dewaxing + bleaching + deodorization process was the best winterization-dewaxing process.
