Custom 25L Stirred Reactor System with Telescoping Stand

Posted on

Parr Reactor Systems are highly customizable to meet application or space requirements. Parr was recently asked to design a 25L Stirred Reactor System that could be easily rolled into the user’s walk-in fume hood for use, then rolled out for storage between experimental campaigns.

The design includes:

  • Telescoping stand
  • Tilt-to-empty vessel assembly
  • Safety interlocks between pneumatic telescoping and tilting systems

New HP/HT Rotating Cylinder Electrode System

Posted on
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

Posted on
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

Posted on

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.

Large Volume Stirred Reactor Systems

Posted on
Parr's new 50 L & 100 L high pressure stirred reactors are ideally suited for scale up or pilot work. The geometry, features, and operation are very similar to that of smaller Parr reactors, but with a volume intermediate between lab-scale and traditional production scale stirred reactors. Custom options are available.

Tilt-to-Empty Feature

Posted on

Emptying large high pressure reactors typically requires a bottom drain valve, which in some applications is undesirable. For researchers working with abrasive slurries, biomass particles or other materials incompatible with bottom drain valves Parr has developed a "Tilt-to-Empty" feature.

Parr Introduces New A2000G High Pressure Electrolyzer Cell

Posted on

For electrochemical research involving carbon dioxide and water reduction.

A2000G Electrolyzer Assembly
A2000G Electrolyzer Assembly

Over the past decade, increasing interest has been directed towards utilizing carbon dioxide in generating liquid fuels and chemicals as a means to a sustainable, carbon-neutral based economy. The production of either carbon monoxide (CO) or synthesis gas (syngas), a combination of CO and H2, electrochemically from CO2 and H2O is an attractive option combining sustainable energy utilization and carbon recycling.

The new Parr A2000G High Pressure Electrolyzer Cell provides a unique and reliable hardware platform with many options for facilitating research in this area. The electrolyzer cell has a maximum working pressure of 10 MPa (1450 psi) at 200 °C. It is designed for quick assembly and reassembly. The flow-thru electrolyzer cell adopts a unique circular planar design for the titanium cathode flow field and the corresponding 316 Stainless Steel anode flow field. Other materials of construction are available.
