Sunresin provides a mature ion exchange resin process for acetic acid purification, which can remove bromine or chloride ions in acetic acid to less than 5ppm, or undetectable levels. The fixed bed mode is recommended for the ion exchange process for acetic acid purification, which runs continuously and removes impurities through the front and back resin columns to improve the removal accuracy and ensure the maximum utilization of the resins. For details, refer to the figure below.

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.

On December 1, Fang Hongwei, Secretary of the Xi'an Municipal Party Committee, led a delegation to visit Sunresin New Materials Co., Ltd at the Sunresin Campus. Accompanied by Dr. Gao Yuejing, chairwoman of Sunresin, Fang Hongwei and the delegation visited Sunresin’s provincial functional polymer adsorption/separation technology research center, the protein purification laboratory, the cell culture lab, and the electronic grade ultrapure water test line. Dr. Gao also gave a detailed introduction to the company's achievements in R&D investment, talent building, technological innovation, as well as its efforts in ensuring a safe working environment facing the pandemic.

2022 China Nuclear Energy High Quality Development Conference took place from 15-17 November in Shenzhen World Exhibition & Convention Center. Scientific research institutes, industry associations, operators, service providers, regulators in the field, as well as specially invited experts and scholars, gathered together to discuss the development and opportunities of China's and the world's nuclear power industry.

As a leading company in adsorption technology from China, Sunresin has always had a good brand awareness and reputation in Turkey over the years. The overall solution of adsorption and separation technology provided for ETI in this project meets the customer's demand for high-quality products and sustainable development, which also marks another milestone for Sunresin’s international footprint in nickel and cobalt extraction solutions in a one-stop-shop fashion.

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.
