This channel that you have started is one of the best, you are sharing the most technical channel with all of you, through which all the information is very useful there is no alternative opinion but the request I make to you is to give oral descriptions in all your videos with appropriate site photo only then It will be even better, so in the future when you post videos related to oil refining with site photos and oral explanation, it will be even better, a lot of people will want to see it.
