GUOLIN Wins Orders for 18 Large-Scale Ozone Systems for CHN Energy
GUOLIN secures orders for ten 120 kg/h and eight 150 kg/h ozone systems for CHN Energy's Zhundong and Ningxia Coal wastewater projects.
GUOLIN has secured three equipment contracts for CHN Energy coal-chemical wastewater projects, covering 18 large-scale ozone systems rated at 120–150 kg/h. The orders bring GUOLIN's high-capacity manufacturing and system-integration expertise to major projects in Xinjiang and Ningxia.
The company announced the orders on 29 October 2026 and reported that part of the 120 kg/h equipment had already been dispatched. Delivery is progressing alongside manufacturing and coordination with the project engineering teams.
Three contracts across two major project locations
Two contracts serve CHN Energy's Zhundong coal-to-gas development, which has a planned natural-gas production scale of 2 billion cubic metres per year. A third serves the Ningxia Coal coal-to-liquids branch's concentrated-brine salt separation and resource-recovery upgrade.
| Project | EPC contractor | Equipment order |
|---|---|---|
| Zhundong coal-to-gas wastewater treatment | China Tianchen Engineering Corporation | 3 × 120 kg/h |
| Zhundong coal-to-gas wastewater treatment | Sinopec Ningbo Engineering Co., Ltd. | 7 × 120 kg/h |
| Ningxia Coal brine salt separation and resource recovery | Donghua Engineering Science and Technology Co., Ltd. | 8 × 150 kg/h |
For Zhundong, the Tianchen contract includes equipment for concentrated-brine treatment. In Ningxia, GUOLIN's eight 150 kg/h systems are part of the high-salinity catalytic oxidation scope within the purification, impurity-removal and plant-utilities EPC package.
Engineering coordination backed by industrial manufacturing
These orders combine large individual system ratings with multi-unit supply and complex engineering interfaces. GUOLIN's sales and technical teams worked with the EPC companies through technical discussions and drawing reviews, bringing equipment configuration, system integration and production scheduling together.
The project teams reviewed discharge efficiency, gas quality, long-term operating stability and energy requirements. GUOLIN worked with the process teams on core equipment for the high-salinity catalytic oxidation duties, drawing on its established ozone equipment development and manufacturing capabilities.
A leading Chinese manufacturer of industrial ozone systems
GUOLIN is China's first publicly listed ozone-system manufacturer and a leader in China's industrial ozone equipment sector. Listed on the Shenzhen Stock Exchange in 2019 under stock code 300786.SZ, the company designs, manufactures and integrates complete industrial ozone systems.
The 18-system order programme puts that capability to work at substantial scale: ten 120 kg/h systems for Zhundong and eight 150 kg/h systems for Ningxia Coal. For international plant owners and EPC teams, the projects provide a clear reference for GUOLIN's large-equipment manufacturing and multi-party engineering coordination.
