Transitioning to the Field of Chemistry

Yes, of course one can become a chemical process or operations engineer with an electrical engineering degree. It would help if you also have a Professional Engineer license. The real question is: does the employer and/or government agency require a specific credential for the position? I know some locations do not require any additional certification to operate a system. I know some jobs do require additional certification beyond an Electrical Engineering degree. For instance, here an Electrical Engineering degree is an insufficient credential for wiring a residence for mains power. An Electrician's license is required to legally do this work.

(This is ironic. I'm listening now to a brass ensemble version of Captain Beefheart's "Dropout Boogie." What a perfect accompaniment for this question.)

Rereading the sparse job description you provide tells me you could be trying to operate an automated bakery, brewery, farm, oil refinery or even a munitions fabrication. Not all of those positions require any license at all. Those that do require different licenses.

As an electrical engineering student doesn’t make a person an “electrical engineer”, which means that upon completion of your studies you may work in any field depending mostly on your interest, and personal inclination.

Your success is dependent mainly upon your ability to perform and apply in practice whatever you learned in your field of studies

Which means that inclination based transition can easily be achieved while you are still studying.

Yeah, definitely possible, especially in operations. Your electrical engineering background can be useful in a chemical plant, particularly with controls and automation. Process engineering might be harder since some companies prefer chemical engineering graduates, but I’d check the job requirements first before deciding you need another degree.
