I've never seen a built up beam span that far, so I would not attempt it. You have to calculate the load to determine what size beam you need. If you're not comfortable with that, then you should hire an engineer to do it for you. Anyway, if you want to use a PSL, here are some instructions on how to size them properly

To span 22' I had to go with 3x 16" LVL's - supporting room above & roof loads
You need to have the size engineered by a lumber yard possibly or an engineer
There is no guessing on a beam this big
