Processing an IBC with a rotating bed reactor

The IBC, also called “tote”, is a common storage container in many industries. In a chemical manufacturing plant or a waste treatment facility there might be hundreds of these or more, with a capacity of approximately 1,000 liters (275 gallons). Whether they are filled with raw material, finished product or waste, the transfer of liquids to and from IBCs can be cumbersome or even hazardous.

The rotating bed reactor enables processing directly in the storage container. The IBC add-on is easily installed on your IBC for processing without having to transfer the liquid to and from treatment plants or other reactor vessels.

In this example, 600 L of a liquid was decolorized using the ProRBR IBC add-on. The rotating bed reactor was filled with an ion exchange resin. The treatment time was on the order of hours, and the time can be controlled by adjusting the stirring speed of the rotating bed reactor.

Our customers have used the IBC add-on to remediate contaminations and produce valuable materials directly in the storage container. This has increased their responsiveness to variations in the quality of the starting material.

Details

Methylene blue (3 g) was dissolved in 600 L of water. The adsorbent Purolite® NRW1160 (4.2 L) was placed in a SpinChem® S5 RBR. The ProRBR IBC add-on was used to deploy the rotating bed reactor and operate it at a speed of 147 rpm. The data was acquired using a UV-VIS spectrophotometer.
