Beam Over CMU Non-Bearing Wall 2

I have a CMU partition wall with wide flange roof beams over it. The CMU is notched around the roof beams so they can pass over the wall without bearing on it. I need to seal off the spaces on each side of the wall from each other. How do I seal off the pockets around the beam? I can't use anything that transmits load from the beam to the wall. Dry-pack mortar or grout is out of the question. Is anyone aware of any products that can tolerate the beam deflection while keeping a seal?

spray foam? Drywall and an Emseal? transition membrane like blue skin? a slotted plate?

Why are you sealing this gap as that can eliminate many options which aren't fire proof or air tight.

This is a wastewater treatment plant building. The spaces on different sides of the wall have different classifications. One side has potential for H2S gas, and the other side is an electrical room we don't want gases getting into.
 
Mineral wool insulation and a firestopping type flexible caulking? It really wouldn't be any different than sealing a penetration through a fire wall.
 
Here is a similar detail from Hilti.

I would normally defer to an architect or some other specialist for something like this. I don't know why anyone would ask a structural engineer to design a seal against H2S gas.
