    INTRODUCTION

     

    Tubular reactors are used in a continuous flow mode with reagents flowing in and products being removed. Single-phase flow in a tubular reactor can be upward or downward.  Two-phase flow can be co-current up-flow, counter-current (liquid down, gas up) or, most commonly, co-current down-flow. Tubular reactors can have a single wall and be heated with an external electric furnace or they can be jacketed for heating or cooling with a circulating heat transfer fluid.  External furnaces are typically rigid, split-tube heaters.

     

     

     

    FEATURES

     

    Salient Features

     

     

    • Tubular reactor systems are highly customizable and can be made to various lengths and diameters and engineered for various pressures, temperatures and materials of construction. 

     

    • A split-tube furnace is provided for heating these vessels. Insulation is provided at each end, to minimize heat loss and prevent the end caps from being heated. The heater length is normally divided into one, two, or three separate heating zones, although it can be split into as more zones if required.

     

    • Several fixed internal thermocouple in each zone or a single moveable thermocouple in the center line thermowell that can be used to measure the temperature at points along the catalyst bed. External thermocouples are typically provided for control of each zone of the heater

     

    • Cooling condensers are available to cool the products of the reaction.

     

    • The reactor pressure is maintained by a Back Pressure Regulator (BPR) installed downstream of the reactor. 

     

    • Tubular reactors operating in continuous-flow mode with both gas and liquid products will typically require a Gas/Liquid Separator. The separator is placed downstream of the reactor, often separated from the reactor by a cooling condenser.
