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 order to solve the problem of inefficiency in the traditional fixed bed mode in vanadium extraction from stone coal, Sunresin has developed its Sepsolut SMB system, a 24/7 automatic operation system that improves resin efficiency and product quality, while reducing consumption and production costs, by turning large columns into smaller ones in series connection, with automated monitoring devices ensuring the smooth operation.

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.

In the chlor-alkali industry, the use of ion-exchange membrane electrolyzers to produce sodium hydroxide has become a common practice. However, this membrane method requires that the content of calcium and magnesium ions in the brine into the tank be less than 20ppb. The old refining method can only reduce the content of calcium and magnesium ions in the brine to about 1 ppm.

Sunresin’s professional and clean packaging has been recognized by customers both in China and around the world.

In nature, substances appear in the form of mixtures. Our job is to separate and to purify in order to bring value to industries. Check out why separation technologies are essential in today’s world and why purity is of vital importance to industry applications such as in semiconductor, bio-technology and hydrometallurgy industries.

As the world transitions to “Green Energy”, Lithium has become one of the most sought-after metals in battery production which empowers industries such as Electrical Vehicles. Sunresin’s adsorption technology (adsorbents, Simulated Moving Bed equipment and industrial process) have been widely and successfully used in a number of Lithium Extraction projects.
