From January 14 to 16, 2026, the "2026 China Modern Coal Chemical Industry Technology Innovation and Industrial Upgrading Conference" was successfully convened in Yulin City, Shaanxi Province. Centered on the theme "Technology Leadership, Innovation-Driven Development, and Building a New Development Pattern for the Modern Coal Chemical Industry ", the conference aimed to thoroughly implement the national energy security strategy, promote the clean and efficient utilization of coal, accelerate the industry’s transition toward high-end, diversified, and low-carbon development, strengthen the synergy between technological innovation and industrial advancement, and contribute to the attainment of the "dual carbon" goals.

Currently, China’s modern coal chemical industry stands at a critical juncture of transformation, upgrading, and pursuit of high-quality development. As a vital component of the national energy strategy, it plays an indispensable role in safeguarding energy security, advancing the clean and efficient use of coal, and boosting the economic and social development of western China. However, guided by the "dual carbon" goals, amid increasingly stringent resource and environmental constraints and intensified global competition in energy technologies, the industry is undergoing unprecedented and profound changes in its connotation and development pathways. Hundreds of industry elites from coal chemical production enterprises, research institutes, universities, technical service providers, and equipment manufacturers gathered in Yulin, Shaanxi, to jointly explore cutting-edge technologies, key equipment, green development pathways, and business model innovations in the field of modern coal chemical industry.

Hope Deepblue Air-Conditioning Manufacturing Co., Ltd., recognized as a model enterprise for energy conservation and carbon reduction in the industrial sector and an active participant in the green transition of the coal chemical industry, was invited to attend the conference. Xiong Ziping, the company’s Chief Engineer and a seasoned industry expert, delivered a special report titled "How to Achieve Efficient Utilization of Waste Heat in Coal Chemical Industry" during the event.

After more than two decades of development, China’s coal chemical industry has established the world’s largest and most comprehensive industrial system, emerging as a crucial pillar for ensuring the diversified security of the nation’s energy and chemical raw materials. Nevertheless, its inherent high-carbon attribute, enormous water demand (with most projects concentrated in the Yellow River Basin), along with issues such as severe homogenization of certain products and insufficient supply of high-end new chemical materials, have become particularly prominent under the "dual carbon" goals. For instance, statistics indicate that in the coal-to-olefins segment, approximately 5.8 tons of carbon dioxide are emitted per ton of product; the carbon emission intensity of the coal chemical industry can reach up to 10.8 tons per unit of product, and its coal consumption accounts for about 24% of the country’s total coal consumption, second only to the power industry, placing the sector under immense emission reduction pressure.

By leveraging Hope Deepblue’s lithium bromide absorption technology, substantial amounts of low-grade waste heat and residual heat resources in the coal chemical industry (including steam, exhaust steam, material vapor, high-temperature materials, waste hot water, heat transfer oil, biomass fuel, and flue gas) can be fully utilized across all temperature ranges, turning waste into valuable resources. Grade-matched utilization of waste heat is the most compelling solution: through refrigeration or temperature elevation via Type I heat pumps (heat-enhanced type), it directly replaces high- and medium-grade heat sources, thereby eliminating energy loss caused by heat exchange. For upgraded utilization of waste heat, Type II absorption heat pumps (temperature-raising type) are adopted to increase the temperature of low-grade waste heat by 30–50℃. The upgraded heat can be converted into high-temperature hot water or steam for further application, or utilized for waste heat power generation or direct expansion work to realize the Organic Rankine Cycle (ORC).

Hope Deepblue’s lithium bromide absorption units facilitate waste heat recovery and utilization across a wide range of production scenarios in the coal chemical industry, including distillation columns, coal coking processes (such as primary coolers, circulating ammonia water systems, and ammonia distillation columns), maleic anhydride hydrogenation units, condensation kettles, depropanizer columns, and polyester chemical fiber production lines. This technology significantly reduces energy consumption and promotes green production and eco-friendly emissions in the industry. Take the ammonia distillation column in the coking industry as an example: by recovering waste heat from the top vapor to replace the overhead partial condenser, the lithium bromide heat pump generates low-pressure steam that partially substitutes the heating steam for the bottom reboiler, with an investment payback period of only 2–3 years. For a coking project with an annual output of 1 million tons of coke, this solution can save 29,700 tons of steam and 2,860 tons of standard coal annually, cutting costs by 4.45 million yuan. It also reduces carbon dioxide emissions by 7,500 tons, sulfur dioxide by 210 tons, and nitrogen oxides by 110 tons per year, delivering remarkable economic and social benefits.
