I wanted to know if there was a way that I can get a quick divorce based on being separated for more than a year and also that fact that I don't know where he is.

Nope, in fact the fact you don't know where he is, will make it take longer and cost more money ( than knowing where he was and he agreeing to it)

You will need an attorney, have to do a search according to court rules, post legal ad in proper news paper, wait proper waiting period and then have a court hearing
