This Tubular Reactor System
can be used with its three
reactors configured for series
or parallel operations.
This Continuous Flow Stirred Reactor System is on a Cart
with with our new Modular Frame System. This modular
frame allows for easy access and flexibility in hook-ups,
accessories, and flow.
of the reactor, often separated from the reactor
by a cooling condenser. In the separator vessel,
liquids are condensed and collected in the bot-
tom of the vessel. Gases and non-condensed
vapors are allowed to leave the top of the
vessel and pass to the back pressure regulator.
It is important to operate the BPR with a single
fluid phase to prevent oscillation of the reactor
pressure.
The gas/liquid separator can be sized large
enough to act as a liquid product receiver that
can be manually drained periodically. Many of
the non-stirred pressure vessels made by Parr
are ideally suited for use as gas/liquid separa-
tors. Vessels of 300, 600, 1000, or 2000 mL are
commonly chosen.
Control and Data Acquisition Systems
A variety of solutions exist to meet the needs
of system operators. System accessories such
as heaters, mass flow controllers, and pumps
can be obtained with individual control packages
to create a manual, Distributed Control System
(DCS) based on our 4838 and 4848 Controllers.
As the number of channels to be controlled
increases, economics and convenience will
often dictate that the distributed system of indi-
vidual controllers should be replaced with the
computer-based Model 4871 Process Controller
(PCC). The 4871 Process Controller is described
in detail in Chapter 4 of this catalog beginning
on page 95.
