Chelating Resin for Brine Refining in The Production Of Caustic Soda

Lanlang ® TY CH530 is a kind of chelating resin that is comprised of a styrene and DVB copolymer with a unique macroporous structure and weakly acidic aminophosphonic (-CH2NHCH2PO3-) compound. This exceptional product boasts the ability to effectively fix and chelate a variety of cations in a wide range of solutions, even those with high content. Its positive and beneficial properties make it an excellent choice for a wide range of applications.

With the increasing demand for caustic soda in various industries ranging from pulp and paper to food and beverage, the production of this chemical compound has become an important process in the manufacturing sector. One of the key steps in the production of caustic soda is the refining of brine. Brine refining plays a critical role in improving the quality and purity of the final caustic soda product.

Brine, which is a concentrated solution of salt and water, is the primary source of sodium chloride used in the production of caustic soda. However, brine contains impurities such as magnesium and calcium ions, which can hinder the effectiveness of the chemical reaction involved in the production of caustic soda. Therefore, it is necessary to remove these impurities through brine refining.

Brine refining involves various techniques such as precipitation, ion exchange, electrochemical techniques, and membrane processes.

Lanlang is the member of American Water Quality Association. In 2016, Lanlang obtained WQA Certification with NSF / ANSI61 and 372 standard. And in 2022, Lanlang obtained NSF Certification with NSF/ANSI44 and 42 standard.
