Large Volume Stirred Reactor Systems

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

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

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.

Tubular Reactor with 360° Rotation

When an unusually long or heavy tubular reactor is needed, the logistics of removing the reactor from the stand for cleaning or loading and removing catalyst or other internal packing can be daunting. Parr has designed a mechanism integrated into a custom tubular reactor stand which not only secures the reactor and furnace during operation, but makes easy work of accessing and manipulating large tubular reactors.

The furnace is hinged such that it easily swings out of the way. Once clear of the furnace the tubular reactor support slides out to an extended position for easier access. The tubular reactor is then easily rotated and locked securely into a upright, horizontal or inverted position. This allows easy access to the inside of the reactor for cleaning, inspection, loading of catalyst or other internals, and gravity-assisted discharge of the same.
