Gas–Liquid Separator & KO Drum Sizing with Rohit Kumar Yadav

🛢️ Simplify Separator and KO Drum Sizing

The ChemicalWala Separator & KO Drum Live One-Page Calculator is a practical Excel-based engineering tool developed for preliminary gas–liquid separation and vessel-sizing studies.

Select the vessel orientation and enter the gas and liquid flow rates, fluid properties, operating conditions, droplet size and liquid-holdup requirements. The calculator automatically determines the key process-sizing parameters.
