I am not sure about Chemical Engineering at IIT Kharagpur but I can vouch for IIt Bhubaneswar, you can opt for any ECE, EE, or Mechanical engineering from IIT Bhubaneswar.
Both IIT Kharagpur and IIT Bhubaneswar are good IITs. So, it’s difficult to pick a single one.
IIT Kharagpur is one of the top IITs in India, ranking at 3 according to NIRF rankings 2019. The placement record of Chemical Engineering in IIT Kharagpur is quite good too. According to the 2019 placement report, 80% of the students got placement offers while a few of them went on to pursue higher education. Abbott India Limited, ITC Limited, Aditya Birla Science & Technology Company Ltd, Jacobs Engineering, Ansys India, Johnson Matthey India Pvt Ltd are a few of the top recruiting companies in 2019 at IIT Kharagpur.
While IIT Bhubaneswar is a new name among IITs, it’s doing quite well in placement. The ECE branch of IIT Bhubaneswar started recently and the first batch will graduate in 2020, as a result, there is no previous placement record. But the placement record for Electrical Engineering and Mechanical Engineering is quite good. The 2019 placement record reveals 86% and 83% of students got job offers from Electrical Engineering and Mechanical Engineering respectively. Also, according to the NIRF 2019, IIT Bhubaneswar is ranked 26, which is a good rank considering it’s a new IIT.
