Dehydration in atmospheric and vacuum distillation units
Thread Content
Our installation consists of a vacuum distillation column (6.25 t/h) and a atmospheric pressure column (2.5 t/h). The raw material to be processed is complex in composition and contains a high water content (about 30%); therefore, it is necessary to dehydrate the raw material before feeding it into the columns. Would three horizontal screw separators work for this purpose? Are there any manufacturers in China that do this well? What’s the approximate budget?
Static dehydration is generally used. Crude oil has a significantly different specific gravity from water, allowing it to be dehydrated using a centrifuge.
Our raw material is not crude oil; it is chemical waste liquid. Are there any centrifuge manufacturers in China with good performance?
The water in our raw materials has a low density, so it stays on the upper layer and cannot be separated out
A centrifugal oil floating tank can be used; as you said, the water should float on the surface at the top of the tank. You can contact the equipment manufacturer for inquiries.
I suggest you take a look at the oil skimming process“”
