I've had 20 running at once, back when I had power leveled to Level 40 in a month and spent two weeks catching up on the main quests, then I bought a bunch of Premium Characters and Buildings so I had several Premium Quests going at the same time as well. Only 6 Task Book quests can be shown (at least on my tablet) so you have to scroll through the additional quests, with the inactive ones at the top, then the active ones ending soonest next, and the one ending last at the bottom of the stack.

This person likely used a back to get content that hasn't even been released yet, so it would be easy to have 30 or more concurrent quests, most of them Premium Quests involving the new Characters.
