Problem

To produce commercial grade 30% to 37% Hydrochloric acid use of HCL Synthesis unit having 2000⁰C Top fired Combustion chamber made from impervious graphite (steel jacketed) process Hydrogen & Chlorine.

Unabsorbed HCL will then be taken to the Tail gas tower (TGT) for better absorption of all HCL traces & remaining gas is vented. Customer was facing a challenge to install a flowmeter for Vent gas having HCL trace gas (<5ppmv) & water vapor at very low velocity where NO solution is available.

After studying thoroughly our expert proposes a customized flow solution with HALAR Coated sensor probe which can work well as wetted parts.

Solution

Leomi – 586 Insertion Thermal Mass flowmeter:

Can handle corrosive gas environments with long life.
Senses very low-velocity upto 0.2 m/s make this application easy.
High turn-down ratio of 100:1 ensures high rangeability.
No pressure drop
Works well even in high water vapors & moisture

Application

Vent process gas flow measurement in the Chemical Industry.
