The Core-Shell multi-mode chromatography medium is a new multi-mode agarose chromatography medium independently developed by Sunresin Technology, used for purification and polishing of biological macromolecules such as viruses.

Erythritol, as the main glycogen in sparkling water, has seen a rapid increase in demand in the past two years. However, while the production scale has expanded year by year, market competition has become increasingly fierce. Therefore, product quality control and operation cost have become the key to success. This is a Simulated Moving Bed system for the erythritol purification process. It is designed, manufactured, installed and implemented by Sunresin. Thanks to this SMB system, a steady output of quality product is ensured at a reduced operation cost.

As a leading separation solution provider in China, Sunresin has built its own and unique technical expertise both on Simulated Moving Bed (SMB) and fixed bed basis, thanks to years of researches and developments carried out over a period of 20 years. With the combination of cutting-edge resin technologies and automation control systems, Sunresin has successfully designed and delivered numerous systems for customers in applications such as metallurgy, (Lithium, Nickel, Cobalt) environment protection (waste water, VOCs) and food industry. (juice, sugar, etc)

Its extraction section adopts Sunresin’s proprietary SMB (Simulated Moving Bed) system. This system integrates adsorption, water washing, desorption, regeneration and other processes. Compared with the traditional fixed bed system, Sunresin’s SMB system significantly saves resin consumption and requires less floor space. It also leads to a higher level of intelligence, lower consumption of energy and higher concentration of the desorption solution, reducing the CAPEX and OPEX by about 50%. Through the implementation of the automatic system, the complex adsorption-regeneration process can be completed within the system with reduced manual intervention and therefore less risks and errors, thus making the production more stable.

As a leading provider of separation and purification materials and solutions in China, Sunresin has successfully industrialized the Seplite® resins as well as the Sepsolut® SMB system for steviol glycoside purification in various EPC projects since 2009. While improving product quality, Sunresin’s technology also improves production efficiency and reduces cost, thus promoting the technological upgrading in the whole stevia industry.

Vanadium is a silver-white refractory rare metal. It is ductile, hard, non-magnetic, and resistant to corrosion. Given its stable features in alkali, sulfuric acid and hydrochloric acid, it is widely used in machinery, automobile, shipbuilding, railway, aviation, bridge, electronic technology, national defense and other industries.

In the purification process, Sunresin’s uniform-particle-size ion exchange resin, specifically developed for lactic acids, removes impurities, ashes and proteins from the lactic acid fermentation broth, in order to provide high-quality raw materials for the synthesis of polylactic acid.

As a rare metal with high energy density, cobalt is an important element of ternary batteries. With the rapid development of the Electric Vehicles industry, the supply-demand relationship of cobalt has been tight for a long time. Congo (DRC) is a cobalt-rich country with its output accounting for up to 70% of the global output.
