Turning Waste Heat into Valuable Steam with SLG Heat Pump Technology

At the Xiangfeng Petrochemical project in Yunnan, China, SLG has successfully transformed converter gas waste heat into valuable low-pressure process steam using its lithium bromide absorption high-temperature heat pump.

As one of China's first demonstration projects utilizing converter gas waste heat for steam generation, the project demonstrates how industrial waste heat can be converted into a reliable energy resource—reducing both operating costs and carbon emissions.

The system generates 8.88 t/h of low-pressure steam, saves approximately 71,000 tons of steam annually, reduces cooling water consumption by 50%, and delivers annual economic benefits of approximately USD 1.5 million, with a payback period of just one year. It also saves approximately 9,000 tons of standard coal and cuts 185,000 tons of CO₂ emissions every year.

Applicable to ammonia, coal chemical, coking, and distillation processes, SLG's waste heat recovery solution helps industries improve energy efficiency while advancing their decarbonization goals.

With over 40 years of expertise in industrial energy-saving technologies, SLG continues to deliver innovative solutions that turn waste heat into sustainable value.
