Glass distillation unit

[ashishmali28]

According which code ,pure glass distillation column is designed (No glasslined reactor)?what's is its maximum pressure (opearting)?

These vent to atmosphere so there is no positive pressure. That is a key point of the design.
Actually there is a small trap to prevent air from entering so the pressure may be 0.5" H2O.
There are guides for these in some of the Hygenic Codes (BPE or EHEDG) but I don't think that they are actually rules.

= = = = = = = = = = = = = = = = = = = =
P.E. Metallurgy, consulting work welcomed

To my knowledge there isn't a design code for a pressure vessel made entirely of glass. I assume you are asking about a large-scale vessel rather than a lab-scale vessel. I have experience with large glass-lined pressure vessels, but I have never heard of one made entirely of glass - that doesn't sound safe or economical.

Glass-lined pressure vessels are made by a number of manufacturers. The outer metallic shell provides safety and physical strength. ASME Sec VIII Appendix 27 has requirements for this design.

We had a relatively large (20 ft) glass column in my university as a "pilot" lab for educational purposes. I've seen other instances of pilot scale glass columns.

As a pressure vessel though and to specific pressure vessel codes? I don't think that's feasible since glass can't be assigned a pressure rating as far as I know.
