油脂精炼脱臭中高温油油换热器的应用实践

Application practice of high temperature oil-oil heat exchanger in deodorization section of oil refining

对植物油精炼脱臭中的几种高温油油换热器进行对比,分析了各自的特点。在考虑不同工艺要求、投资成本以及脱臭油品质的情况下,降膜换热器适用范围最广,真空热回收换热器适用于大豆油、菜籽油等油品的冷热油热交换,Compabloc全焊型板式换热器适用于玉米油、葵花籽油的冷热油热交换。

The high temperature oil - oil heat exchangers used in vegetabel oils deodorization section were compared, and the characteristics of the oil- oil heat exchangers were analyzed. Considering different process requirements, investment cost, and the quality of deodorized oil, the falling - film heat exchanger had the widest application range. Vacuum heat recovery heat exchanger was suitable for the heat ex- change of soybean oil, rapeseed oil, etc. Compabloc plate heat exchanger was suitable for the heat ex- change of corn oil and sunflower seed oil.
