My cousin gave me Techron Diesel and on its bottle neck is 19079. Is it made in 2019?

Doesn't really matter as this stuff is stable over long periods of time. FUEL is what you have to worry about aging out.

Does this also help clean out the exhaust system? such as the egr valve and dpf

No, it’s for fuel injectors and fuel lines clog cleaning

Emulsifier or demulsifier?

My best non professional answer is an emulsifier.
