Brine treatment within a resource-recovery upgrade

CHN Energy Ningxia Coal's coal-to-liquids branch is upgrading concentrated-brine salt separation and resource recovery. GUOLIN's equipment order concerns the high-salinity catalytic oxidation system within the purification, impurity-removal and plant-utilities package.

The equipment is being integrated into an industrial brine-treatment project whose wider purpose includes salt separation and resource utilisation. The supply package brings ozone equipment into that wider process and utility design.

Eight units at 150 kg/h

The contract specifies eight systems rated at 150 kg/h each, giving a combined ordered nameplate ozone-generation capacity of 1,200 kg/h. Donghua Engineering Science and Technology Co., Ltd. is the named EPC contractor for the relevant package.

GUOLIN worked with the process and engineering teams on equipment for the high-salinity catalytic oxidation duty. The company announcement describes technical discussions on discharge efficiency, gas quality, long-term stability and energy requirements, together with drawing reviews and system-interface coordination.

Industrial scale backed by manufacturing capability

The eight-unit order combines large individual equipment ratings with a substantial multi-unit manufacturing commitment. It is part of the 18-system CHN Energy order announcement published by GUOLIN on 29 October 2026.

GUOLIN is a leading industrial ozone-system manufacturer in China and the country's first publicly listed ozone-system manufacturer. The Ningxia order brings that manufacturing and integration capability to a demanding coal-chemical brine-treatment application. The project milestone recorded here is the confirmed equipment order.
