Experimental and simulation study of instabilities in a horizontal thermosyphon reboiler

Experimental and simulation study of instabilities in a horizontal thermosyphon reboiler

Thermosyphon reboilers are widely used in the chemical industry because of their high heat transfer rates, limited space requirements, resistance to some types of fouling, and the absence of a pump. They are however susceptible to thermo-hydraulic instabilities, particularly at start-up and low syst...

Experimental and simulation study of instabilities in a horizontal thermosyphon reboiler
description Thermosyphon reboilers are widely used in the chemical industry because of their high heat transfer rates, limited space requirements, resistance to some types of fouling, and the absence of a pump. They are however susceptible to thermo-hydraulic instabilities, particularly at start-up and low system pressures. Flow instabilities are generally undesirable in process industries because flow oscillations may cause mechanical vibration, system control problems and adverse performance. This thesis details the investigation of two-phase flow instability in horizontal thermosyphon reboilers experimentally using a laboratory scale rig and via mathematical modelling.
