Hi Dumpala,

Please understand the fact that this query raised by you is a very complicated one as both are different domains of engineering and thus there is no point of comparison in between then as they are very different from each other.

The faculty of both the departments are very experienced and qualified and each of the departments has dedicated and proper labs for academic purposes at JNTU so both the departments impart a similar quality of education in both the fields.

What you need to understand is, Petroleum Engineering is specially the engineering study related to petroleum production such as drilling, mining, refining, etc and the companies for recruitment in this field are ONGC, HPCL, etc., whereas Chemical Engineering deals with the engineering studies of any and chemicals such as soft drinks, acids, industrial chemicals, chemical bombs, etc and the fields of placement include companies like Coca-Cola, Pepsi, 7Up, Police Department, etc.

BEST WISHES!
