Refining Resin and Technology of Hydrochloric Acid By-product of Chemical Industry

In the by-product hydrochloric acid of chemical production, due to the leakage, entrainment, volatilization of organic chemical raw materials, intermediates, end products and the corrosion of metal pipes during the production process, it contains Fe3+ and organic molecular impurities with color and peculiar smell, which seriously affects the application, and is more difficult to be sold as a commodity, bringing environmental protection pressure as well as economic loss to the majority of chemical production enterprises.

In the face of this reality, Sunresin developed a two-stage resin treatment process of chemical by-product hydrochloric acid by analyzing the impurity composition in hydrochloric acid system and combining his own experience in organic wastewater and heavy metal removal. The self-developed Seplite® LWT510 macroporous adsorption resin and Seplite® MA396 special resin for iron removal are used together to effectively adsorb and remove organic molecules and Fe3+ in by-product hydrochloric acid, realize resource recovery, solve the problem of by-product hydrochloric acid refining, and maximize customer value. At present, this process has been applied in industry and has been well-received by customers.

  • Seplite® LWT510 macroporous adsorption resin


Seplite® LWT510 macroporous adsorption resin is a kind of highly efficient  macroporous resin with uniform pore diameter, super high specific surface area, large adsorption capacity, easy regeneration and long service life. It has been widely used in the adsorption and removal of organic molecules in wastewater of chemical industry, pesticide, dye, medicine and other industries.


  • Seplite® MA396 special resin for iron removal



Seplite® MA396 is a special resin used for the removal of Fe3+ in high concentration hydrochloric acid, with high precision of adsorption and removal. The saturated resin after adsorption can be resolved by simple regeneration. The resin has the advantages of large treatment capacity, easy regeneration, simple operation, strong anti-pollution ability and long service life, and is widely used in the field of hydrochloric acid refining.
