Case Study

According to the forecast from 2020 to 2025, the global lactic acid market is growing rapidly, with the growth rate at about 12.8%. This means the value of the lactic acid market will double every five years, from $1.1 billion in 2020 to $2.2 billion in 2025.

Sunresin’s VOCs treatment resin is a styrene-DVB matrix macroporous adsorption resin with a specially designed resin structure. It has a good mesh structure and a high specific surface area, and can be sieved through the size of the pores. Organic molecules are selectively adsorbed by interaction, intermolecular force or hydrogen bond interaction.

In Sunresin’s method, the hydrophobicity of the resin is further increased, the degree of crosslinking gets increased, and the pore structure gets adjusted. The adsorption resins have a narrow particle size distribution, uniform pore size and high specific surface area. As the size of micropores in the resin is close to the molecular size of perfluorooctanoate in water, which has a strong selectivity of the adsorbates and can therefore further increase the adsorption rate of perfluorinated compounds.

In the production of human vaccines, Sunresin’s multimodal chromatography resins are usually combined with ion exchange chromatography such as Seplife Q Large Scale, or combined with gel filtration chromatography Seplife 4FF to complete the entire purification process.

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.
