| Abstract: | The status quo and same questions about native crude benzol refining are described briefly. The more advanced technique of refining with sulphuric-acid, of waste acid application and the best advanced technique crude benzol refining with hydrodesulfurization of the Litol method or K.K method are described with emphasis. Due to obtaining benzene of good quality and avoiding contaminant of waste acid the hydrodesulfurization of crude benzol refining is approaching to apply the K.K method nowadays. |
