Commercial Scale STT® Equipment

The STT® Reactor is also available for commercial scale applications with working volumes that can exceed 1 liter. Equipment can be made from a variety of metal systems including 316SS, Hastelloy C and titanium. Additionally, we can provide a corrosion resistant finish on iron-containing alloys using a chemical bath nitriding process called carbonitriding that produces a 64 Rockwell C (diamond cone) hardness rating that meets or exceeds stainless steel specifications, is 85% more corrosion resistant than a hard chrome finish, and is 99.9% salt-water corrosion resistant. The commercial systems use double mechanical liquid seals or gas mechanical seals that are industry standards in the chemical processing industry.

Continuous production
Safe for hazardous reactions (ex. slow addition chemistry)
External heat exchanger for precise temperature control
Electronically controlled and available with intrinsically safe control systems
Extraordinary working volume of 1 liter in a compact footprint
Liquid mechanical seal for minimal maintenance
Can be supplied explosion proof if required

The commercial scale system would have different production capabilities depending on the residence time required for the application and the actual working volume. In the case of biodiesel transesterification, this 1 liter working volume reactor is capable of processing over 13 million gallons of biodiesel per year.

All commercial reactors undergo pressure and temperature testing in our reactor test bed to ensure the quality and integrity of the system before shipment. The picture to the right shows a commercial reactor in the test bed.

The STT® process and equipment are covered by multiple patents and patents pending worldwide. STT, Innovator and Magellan are registered trademarks with the USPTO, Hastelloy is a registered trademark of Haynes International, Inc.
