Hello,

There are many government colleges in India offering petrochemical engineering. Since you have not mentioned particular college. I am telling you thr general placements scenario. 

The placements in this feild are very limited because less petroleum resources are available in India. But it is expected to increase in mear future as new petroleum refinery is going to open in Rajasthan. And also many private industries are getting into the market. So the placement might increase. The recruiters are Hindustan petroleum, Indian oil, Reliance, Essar, etc,
