If the same tendancy continues, Beginning and Running alone would need about 13 episodes. Of course, it all depends on whether or not the anime decides to cut content, especially long-winded explanation scenes like the ones in volume 9 and 10.

If it's 24 episodes per season, then likely it would take up some episodes. However, despite Alicization being the longest Arc, it's still too short to take up the whole season, and too long to take up only half of the season to make way for a 5th arc, if there is any.

So likely, the Arc will need to be "expanded" to estimate how many episodes each part of the arc would take up, then cut-outs here and there to fit the season. If I'm right, Alicization should take up a whole 24 episodes.
