“Makers on the Move” Tour Visits Parr

Parr Instrument Company is honored to be part of the Illinois Manufacturers’ Association and IMEC’s Makers on the Move tour for Manufacturing Month. Mark Denzler with IMA, David Boulay with IMEC, State Senator Michael Halpin, Representative Gregg Johnson, Representative Dan Swanson, LaDrina Wilson from the Quad Cities Chamber of Commerce, Parr’s President & CEO Jim Nelson, & Parr’s Machine Shop Supervisor Nate Brown all spoke about the importance of manufacturing to businesses and our community.

Jim Nelson and Parr’s Operations Manager, Stacey Moon led the group on a tour of Parr’s facility while providing an overview of Parr’s products and its 124-year history. Guests were able to see Parr’s skilled machinists and manufacturing team at work creating high-quality Parr reactors, pressure vessels, and calorimeters.

New HP/HT Rotating Cylinder Electrode System

Parr's new High Pressure, High Temperature Rotating Cylinder Electrode (RCE) System was designed to perform corrosion studies as described in ASTM G185 at elevated pressure and temperature. This apparatus facilitates the evaluation of corrosion inhibitors in harsh, real world conditions, up to 200bar/2900psi and 200°C, with or without the presence of CO2 and/or H2S.
Parr’s new system is based on its popular 1 liter stirred reactor design and integrates robust counter and reference electrodes from Corr Instruments with dedicated sequencing software to control Gamry’s 1010B Potentiostat as well as Parr’s temperature and motor controller.

Catalyst Loading Toolkit for Tubular Reactors

Catalyst Loading Toolkit for 5401 Tubular Reactor
Catalyst Loading Toolkit

Loading or removing a fixed bed (aka packed bed) of bulk solids such as powdered catalyst deep inside a long narrow tubular reactor at a precise repeatable depth can be challenging. Parr has created the Catalyst Loading Toolkit to facilitate loading of catalyst in the annulus of our tubular reactors and easily adjust the location and length of the catalyst packing.

Reaction Calorimetry Capability Added to Parr Reactors

Parr 4540, 1.2 L Reactor, with H2 and liquid feeds, equipped for Power Compensation CalorimetryParr has integrated the principles and practice of reaction calorimetry into our reactor systems.

Reaction calorimetry is often used for studying chemical reaction rates and the thermal properties of systems. In chemical processing industries, this technique is used for understanding and mitigating hazards from the scale-up of reactions developed in the lab to industrial-scale reactors. As a reaction is scaled from lab to plant, scalability problems may emerge for various reasons. Issues are often attributable to a lack of understanding of the process chemistry, the inability to remove heat or changes in mixing performance during scale-up. Reaction calorimetry provides this additional level of process understanding.

The principal output from experiments performed in a reaction calorimeter is the heat production rate associated with the processes occurring inside the reactor. The heat production profile becomes the basis for the determination of a number of important operational parameters.
