A process for producing aviation oil from Sangachaly sea crude
- 9 Downloads
Conditions have been worked out for producing aviation oil from Sangachaly sea crude. Aviation oil can be produced from this crude by acid-contact, adsorption, and selective refining methods, but in view of the large consumption of reagents and the low yield of finished oil it is not expedient to use acid-contact refining.
A comparison of the aviation oils produced by the different methods shows that the adsorption and hydro after-refined oils are the best. These oils have better antioxidation properties and are obtained in a higher yield.
The use of hydro after-refining instead of contact after-refining of the raffinate (200% furfural) yields aviation oil whose quality and stability are as good as the commercial MK-22 oil being currently produced from a mixture of Surakhan and Karachukhursk crude. This method is therefore the best one for producing aviation oil from Sangachaly sea crude.
