Hi supratik ! Nit Durgapur is a very good college to do chemical engineering. Not at so high level but good. Last year average package went 4.5 lacs/annum. And highest went to 10 lacs. Well there also good packages of 6-7 lacs. But for this you must work hard to be in top students of your streams because those level of packages are very less in number. After all it will be best if you acquire a m.tech after b.tech so that you can in any overseas oil company. So best of luck to you.
