תיאור

Series 5400 5mL-1000mL Continuous Flow Tubular

Tubular reactors are used in a continuous flow
mode with reagents flowing in and products being
removed. They can be the simplest of all reactor
designs. Tubular reactors are often referred to by
a variety of names:

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. Tubular reactors are used

in a variety of industries:

– Petroleum

– Petrochemical

– Polymer

– Pharmaceutical

– Waste Treatment

– Specialty Chemical

– Alternative Energy

Care must be taken to size these controllers for

the specific gas, flow rate range, and maximum

pressure of operation. A mass flow controller needs

a power supply and read-out device, as well as a

means of introducing the desired set point.

When ordering mass flow controllers, you will need

to specify:

1. Type of gas to be metered

(e.g. N2, H2, CH4)

2. Maximum operating pressure

of the gas (100 or 300 bar)

3. Maximum flow rate range

in standard cc’s per minute

(sccm)

4. Pressure for calibration of the

instrument

Mass flow controllers are

available for use to 1500 psi and

to 4500 psi. Considerable savings

can be obtained if the mass flow

controller is to be used only to 1500 psi.

The schematic at right depicts the installation of a

mass flow controller for the introduction of gas to a

continuous-flow reaction system. Such installations

are enhanced with the addition of a by-pass valve

for rapid filling or flushing.

A purge line can also be added. It is typically

used for feeding nitrogen or helium to remove air

before reaction or to remove reactive gases before

opening the reactor at the end of a run. The purge

line includes a shut-off valve, filter, metering valve,

and a reverse-flow check valve.

Shut-off valves can be automated when using a

4871 Control system.
