Thank you.   Of all the processes in oil technology, the most common is hydrosulphurization process. The range of derivatives that undergo refinement process by this procedure is extensive: from light petrol, petrol, petroleum to diesel fuel and even to atmospheric residues.

	Alan.es  +  238981 Thu, 22 Jun 06 12:01 PM Yes, it's OK. It wasn't a term known to me but it comes up straightaway on Google and is the terminology for 'the substances which are left after a distillation at atmospheric pressure'. make sure you always put - - hydro-de-sulphurisation.

I guess the article should be added. A native should comment on this! I would omit the <process>, because just "refinement" is OK. Otherwise maybe "...that undergo a refinement process".
