I am not sure if I fully understand the question, but here goes. If you are already on one engine, you should plan to land at Flap 22 approaching at Vref 22 plus whatever additive is needed for wind etc (typically plus 5 to 10 knots). In the event of a missed approach the climb speed should then be not below Vref 22 until reaching acceleration altitude. This is close enough to V2 for flap 9 (which is the flap selected during the OEI go-around) for all practical purposes.
It doesn't help that some operators don't publish Vrefs for flap 22 but expect you to remember to add 10 knots to the flap 45 Vref, then the corrections on top of that. Just to make life hard when you least need it!
