Decolorization at 7,500 L using a mobile reactor

Any producer might need to modify their process because of variations in the available materials or changing demands on the product. However, installing new equipment in a production plant is a costly, time-consuming, and disruptive process. Modifying existing infrastructure often requires extensive downtime, regulatory approvals, and significant capital investment.

The Plug-In Rotating Bed Reactor (RBR) solves these problems by offering a mobile, easy-to-connect solution that integrates with existing vessels or liquid flows. No major modifications are needed, and the installation is quick. With the Plug-in RBR, you gain the flexibility to meet the evolving demands on your process.

 

Plug-in rotating bed reactor connected to a larger reactor vessel

 

In this application we decolorized a reactor vessel containing 7,500 L of solution, using a small-footprint Plug-in system. The volume of the mobile reactor was only 50 L, and the footprint was that of a single shipping pallet. The plug-in system, housing the RBR S14 containing 12 L of the ion exchange resin Purolite NRW1160, was connected to the main reactor. After recirculating the liquid from the main reactor vessel to the small plug-in system, the ion exchange resin had captured the ionic colorant.

Details

A 7500 L reactor vessel was filled with municipal tap water. Prior to the decolorization experiment, the water was de-ionized by the use of Purolite MB400 mixed bed resin (12 L) loaded in an RBR S14 deployed in tank. Methylene blue (16 g) was added to the deionized water, for a final concentration of 2,14 mg/L. To decolorize the volume of water, a RBR S14 was filled with Purolite NRW1160 SCX resin (12 L). The RBR S14 was deployed in a 50 L vessel connected to the main reactor. A spectrometer probe was placed in the tank for in-line monitoring of the decolorization progress.
