Continuous Flow High Pressure Tube Reactor
Tubular reactor systems to 200 bar and 900 °C, engineered to specification
Max pressure
200 bar
Max temperature
900 °C
Tube reactor with four gas lines, mass flow controller, liquid feed tank with pre-heater, metering pump, gas pre-heater/mixer, tube furnace, condenser, gas/liquid separator, back pressure regulator and gas sampling unit.
For continuous flow systems, tubular reactors have been developed with continuous reactor feed, a variety of pre-heat and heating options, with sample collection systems and product handling. 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.

Construction
Design features
Tubular reactors may be empty for homogeneous reactions or packed with catalyst particles for heterogeneous reactions. Packed reactors require upper and lower supports to hold particles in place; the uppermost packing is often of inert material to serve as a pre-heat section.
It is often desirable to size a tubular reactor large enough to fit 8 to 10 catalyst particles across the diameter and to be at least 40–50 particle diameters long. The length to diameter ratio can be varied to study the effect of catalyst loading.
Temperature is typically controlled by thermocouples located on the outer wall of an externally heated tubular reactor. A movable internal thermocouple is often employed to observe temperature changes as the reaction proceeds through the reactor.
Indo can provide a split-tube furnace for heating these vessels. Insulation is provided at each end so that the end caps are not heated to the same temperature as the core of the reactor. The heater length is normally divided into one, two or three separate heating zones, although it can be split into as many zones as required.
