Continuous Flow Catalyst
Testing Made Easy
Parr Instrument Company's new
Continuous Flow Tubular Reactor
is compact, pre-assembled, and
configurable with a user-friendly
touchscreen interface and easy
installation.
his continuous tubular reactor system includes up to four
gas mass flow controllers, a gas purge line, and optional liquid pump. Useradjustable
high temperature and pressure alarms are tied to safety interlocks
which automatically shut down the furnace, stop reactant flows, and optionally
flush the reactor with inert gas.
The system comes standard with an intuitive touchscreen interface for conInside:

trol, monitoring, and logging of three heated zone temperatures, gas flow rates,
and monitoring and logging of pressure data. The three independently controlled
heated zones with centerline multipoint thermocouple enable controlled reactant
preheat and better control over catalyst bed temperatures.
Reactors are available in the materials Parr has come to be known for in their
stirred reactors, including 316SS, Alloy C-276, Titanium, and Alloy 600. Standard
reactor sizes available include inside diameters of 7, 9.5, 25, and 36 mm, with
lengths of 305, 610, and 915 mm. Cooling condenser, gas/liquid separator, and
manual back pressure regulator are included.
When combined with Parr's new catalyst loading toolkit, continuous flow catalyst
testing has never been easier. This indispensable catalyst loading toolkit includes
a centering solids funnel and tools for uniform repeatable loading of catalyst
or other bulk solids in the reactor annulus while easily adjusting and measuring the
location and length of the packed bed.

Getting the Most Value from a Process Simulator
U
sing a process simulator isn't always a matter of building and
specifying detailed flowsheets. To get the most value from your
simulator, try exploring new ways to use its features to support
your day-to-day needs as a chemical engineer. For example:
* Plot several TPxy diagrams to validate thermodynamic
behavior. While the economic benefits of thermophysical modeling
are not easy to quantify, there is a clear advantage to anticipating
the phase behavior through a range of process conditions.
* Run sensitivity analyses to test system vulnerabilities or to
design a piece of equipment. For example, sensitivity analysis
tools can be used to explore operating parameters like how a
change in feed composition can affect the product streams. It
can also be used for design situations like finding the optimal
feed tray location in a distillation column.
* Build a digital twin of the plant using data reconciliation
technology. Data reconciliation techniques have been available
for some time. Today, process simulators can be linked with
real-time data. Matching the model to that data establishes a
validated digital version of the process.
* Use a pipe segment or a flash vessel to represent pipes,
separators, or something more abstract, such as multiple unit
operations. Many unit operations in simulators have multiple
calculation options built in that can accomplish the desired task
without adding all the equipment in the field to the model itself.

It is easy for busy professionals to get caught up in the impressive
new features, and new users may not be aware of all the legacy
tools available in the program. So, to get the most value from a
process simulator, consider whether all the available technology is
being utilized to its full potential.
This excerpt is based on a larger article which highlights several
more features available in CHEMCAD that users may not be taking
advantage of.
