Reducing downstream processing costs

Bind and elute Ion Exchange (IX) chromatography systems based on the Simulated Moving Bed (SMB) principle has opened a huge field of new applications for adsorption technologies. It has resulted in gradual increase in a number of valuable products being purified using IX-SMB systems.

The innovative XPure-S™ systems developed at XPure combine the traditional SMB advantage of reduced consumption of process fluids (water, eluting and regenerating agents) with an enhanced process flexibility, which results in higher separation efficiency and improved product titers.

XPure has the experience and capacity to design and build custom-made continuous chromatography systems. Being part of a quality and progress-driven international organisation, we listen, understand and deliver solutions to our customer’s demands.

Reducing Costs

XPure has a proven track record to reduce the chromatography process costs by 20-50% thanks to:

  • High resin utilisation resulting in reduced annual resin inventory and buffer consumption
  • Less energy demand due to modular characteristics of the valve blocks
  • Robust, reliable and easy to scale hardware coupled with automation system ensuring a consistent and easy to integrate process
  • High flexibility of hardware and software to optimise individual SMB zones

All this makes XPure SMB technology attractive in terms of Design, Delivery time, Cost, and Smooth (after sales) services.

Research & Development

XPure shares the vision to continuously improve the services it provides to customers. This is why our team of process engineering experts focuses on developing innovative and techno-economically viable downstream solutions that can solve industrial challenges. We aim to enhance the effectiveness and practicality of our solutions through timely collaboration with industrial and academic partners.

Current Projects

We participated in a European Union SPIRE2030 (Horizon 2020) project called PRODIAS (PROcessing of Diluted Aqueous Systems). In the project, along with 8 other project partners, we focussed on the major downstream challenges that inhibit process industries from adopting renewable raw materials as feedstock. As a consortium of academic and industrial partners, we ensured the development of efficient process technologies catering to the challenges in time. Thereby, allowing European Process Industries to function in a both profitable and environmentally sustainable fashion.

In the project, XPure focusessed on developing continuous chromatography processes in both packed bed and expanded bed (EBA) modes. We further optimised our technologies for minimum process liquids, maximum resin utilisation, product titer, scalability, flexibility and productivity.

Antoon Backx

Antoon is a biochemical engineer from the TU Delft. During his Master, he mainly focused on downstream processing and modelling. His first acquaintance with the SMB was during a modelling project, which helps to understand the behavior of such a system. Afterwards he acquired his process and automation knowledge during European research projects in which both aspects played a large role. Currently he is working with the team to develop and improve the automation for EBA chromatography.
