The material that can be used to produce fatty acid has a wide range, any kind of oil & fat is fine. The end product fatty acid produced from this line can be used to produce soap or supplied to other chemical factories.
The basic technique process can be separated into four steps: material acidification ?middle-pressure hydrolysis?dehydration?distillation. End product is high quality fatty acid with while color. The most popular material for this line is oil residue from cotton seed oil. 2500-3000 kg cotton seed oil residue can produce 1000 kg high quality fatty acid. This ratio is not fixed, mainly is depended by the fatty acid content in the oil residue.
This product line gives fatty acid and vegetable bitumen as by-product. Normally, produce 1000 kg of fatty acid can get 300-500 kg vegetable bitumen, which can be used as casting binder or as fuel (replace of heavy oil).
