Large-Scale ASU Projects Continue To Drive Advanced Coal Chemical Development In China

 

The successful award of a major air separation unit (ASU) contract for CHN Energy's Yulin Coal Chemical Project once again highlights the critical role of large-capacity cryogenic ASU systems in China's modern coal chemical industry.

The project includes the design, supply, and technical services for four 100,000 Nm³/h oxygen ASUs, supporting multiple core production processes such as coal liquefaction, coal gasification, oil–methanol co-processing, methanol-to-olefins (MTO), and coal-based biodegradable materials. Located in Qingshui Industrial Park, Yulin City, Shaanxi Province, the project represents one of the region's most comprehensive coal chemical integration developments.

ASU Systems as the Backbone of Modern Coal Chemical Complexes

In large-scale coal chemical projects, oxygen supply reliability, purity, and continuous operation are decisive factors for overall plant performance. High-capacity cryogenic ASU are not auxiliary facilities, but core infrastructure systems that directly impact conversion efficiency, process stability, safety, and long-term operating costs.

Modern coal chemical complexes increasingly rely on:

●Large-scale, high-efficiency cryogenic oxygen ASUs

●Stable long-term operation under heavy industrial load

●Integration with multiple downstream process units

●Energy-optimized designs aligned with environmental targets

These requirements place higher demands on ASU engineering, system integration, and lifecycle performance.
