Process Parameter :
Pressure : 10.8 Kg/cm2(G)
Temp : 170 Deg C
Phase : Liquid but during sampling it is vapor
Concentration :
Installed Devices Tried
No liquid observed downstream at distillate side (after wear plate at 750 mm) → possibly confirms vapor dominance or flashing.
We would appreciate advice on:
any other type of LT suggestion or same LTs with some modification.
Pressure : 10.8 Kg/cm2(G)
Temp : 170 Deg C
Phase : Liquid but during sampling it is vapor
Concentration :
- Aqueous Layer:
- H₂O: ~80%
- MEK: ~19%
- NH₃: ~4.5%
- Others: Minor acetamide/ketazine traces
- Organic Layer:
- H₂O: ~10%
- MEK: ~75%
- NH₃: ~0.5%
- Acetamide: ~2%
- Ketazine: up to 5%
Installed Devices Tried- Non-contact Radar LT (80 GHz & 26 GHz)
– Installed with dip pipe; no improvement, still shows 100% or fixed value stuck @ due to high temperature MEK vapor - Magnetostrictive Level Transmitter (Side chamber-mounted, Reflux side)
– Initially worked, then suddenly shot to 102% or at fixed % with no known process change. - Direct Mount Radar LT
– Same result: false full level reading. - Level Gauge (LG) on Reflux Side
– Shows full due to possible condensation, due to12 mm inlet hole is present on a 1.5" 300# flange. - DP Type LT
– Installed using vent and drain points of LG – same result: reads 100% full. with LP side inverse U loop for vapor condensation.
