Hangzhou Lianghuan Technology Co., Ltd. is an industrial gas service provider dedicated to offering comprehensive solutions to customers in the fields of air separation, rare gases, specialty gases, and related industrial gases. Since its establishment, the company has undertaken more than 300 design, engineering, and investment projects across various sectors, including chemicals, steel, new energy, new materials, and integrated circuits. On October 23, 2025, our company and Hangzhou Lianghuan Technology Co., Ltd. successfully held the launch ceremony and signing ceremony for the food-grade liquid CO2 project in Zimbabwe, Africa. The two parties have established a long-term strategic partnership to jointly expand into overseas markets.

The project utilizes lime kiln off-gas as feedstock. Our company will provide the process package design and complete equipment to construct a new-generation chemical absorption, capture, and purification unit (CO₂ capture, compression, and liquefaction distillation system) specifically designed for CO₂ separation from lime kiln vent gas. Based on data analysis of the lime kiln feed gas and target product quality requirements, the facility employs a new-generation chemical absorption method alongside our company’s advanced technologies and processes—including compression, liquefaction, and distillation—ensuring the final product meets the requirements of the “GB 1886.228-2016 National Food Safety Standard for Food Additive Carbon Dioxide” as well as the procurement standards of Coca-Cola and PepsiCo. The project is scheduled to commence operations in August 2026.
