Process Air Compressor Knockout Replacement Presented By: Saud Saleem Designation: App. Engineer(Mech)
Overview: Introduction Project Handling Cost estimation Problem Area
Introduction: Knockout? A knockout drum is used whenever a process requires droplets to be separated from a vapor stream. T1 Inter Cooler Condensate causing Corrosion Condensate Removed and Drained Out Main Suction T2 T3 Where T2 > T1 Where T3 < T2 Condensed Vapors Knockout Drum
Working Principle of Vane Pack: Flow Vane Pack
Introduction: Background: Existing knockouts were replaced in 1987. Upon inspection in TA-07, heavy corrosion and cracks was observed on impellers. PECO (Original Vendor) informed that knockouts are undersized
