CIP implications on tank design

CIP implications on tank design

CIP implications on tank design

(OP)
Imagine I have an atmospheric tank with ambiant temperature product in it.
It will be routinaly CIP'd in different steps with Hot water, Hot caustic and Cold desinfectant.
What specific design considerations should I consider?

RE: CIP implications on tank design

is it made from carbon steel, stainless steel, fiberglass, etc?

RE: CIP implications on tank design

What are the actual temperatures of the hot and cold fluids? A P&ID would help us understand your situation much better as well.

RE: CIP implications on tank design

(OP)
Stainless steel, vertical, < 30000 litres, conical bottom.

RE: CIP implications on tank design

(OP)
Temperature: hot is 80C, cold is 18C.

RE: CIP implications on tank design

Off the top of my head, you'd need to consider the CIP process temp/pressure and see how that corresponds to your MAWP and design temperature and adjust as needed. Depending on those values you may need a relief valve to protect the tank. Is the tank rated for full vacuum? How is the CIP process controlled and what happens if those controls fail?

RE: CIP implications on tank design

(OP)
Thank you for the guidance !
My understanding is that there are different ways to prevent tank failure due to overpresure or vacuum
- tank design: design for vacuum and overpresure (despite this being in use at atmospheric pressure)
- instrumentation : vent, pressure relief, vacuum relief valve

Would all of the above be applicable here?
