I had to look into wikipedia to know what 6σ (six sigma) is. Its application in refineries can be useful, yet difficult. It may include rational organization of production, with proper forms to complete every day, and systematic check of the quality of products. My understanding is that it is not limited to statistics, but it should intervene in operational procedures, even in the process, to limit off spec products.
If the latter activities are included, it could be interesting for the Chemical Engineer, since he/she would get technical knowledge on a specific process, seen from 6σ view. But your post rather indicates that this 6σ methodology is intended to be applied to the refinery now, won't it? It will need a rather long time to be established, and a young engineer had better deal with a broader activity to get some familiarization with refinery process and equipment. I am living in Greece, where occupation in industry is quite rare today, yet it is a valuable experience for many "white collar" seats you may get in future. I suppose that direct industrial experience is valuable everywhere (for Chemical Engineers), so one should try this way during industrial training.
Of course you may deal with 6σ if you like it (Chem Engineering is flexible), but (in this case) you had better combine it with industrial experience beyond statistics.
I do not know your local market to say whether this could help in finding a job. In Greece 6σ is not known, so it would not help much.
