Kerui Corporation is committed to becoming an expert in gas-liquid mass transfer within the chemical industry. To date, we have provided dozens of customers with highly efficient, energy-saving, and intelligent gas treatment solutions. Our product technologies include chlorine treatment, acetylene purification, chloromethane processing, hydrogen chloride drying, and continuous sodium hypochlorite production. Particularly in the ion-membrane caustic soda chlorine treatment unit, Kerui has developed a proprietary single-tower chlorine drying system. Compared to traditional two-tower or three-tower processes, it offers significant advantages in footprint, energy consumption, acid usage, and product quality.

In the field of brine purification, we have served nearly a hundred chlor-alkali enterprises. From turnkey design and supply for new projects to optimization of existing equipment—such as column internals, distribution systems, and process enhancements—Kerui’s solutions have received widespread acclaim. Building on our success in chlor-alkali secondary brine, we have expanded our expertise to adsorption separation processes in industries such as pharmaceutical chemicals, life sciences, and heavy metal recovery.

Since its inception, Kerui has been dedicated to providing digital and intelligent upgrade services for chlor-alkali plants, helping customers build smart factories. Across all process stages—including primary brine, secondary brine, electrolysis, chlorine & hydrogen processing, and liquid chlorine packaging—we offer specialized intelligent controllers to enhance automation, improve quality, increase efficiency, and reduce energy consumption.
