At the end of September 2021, the Phase II indirect cooling upgrade project for the fixed-bed gasification unit at Shanxi Jinxiang Coal Chemical Co., Ltd., constructed under EPC contract by CAS Hefei Coal Gasification Technology Co., Ltd. (“ZHGAS”), achieved mechanical completion and began system commissioning and pilot testing as scheduled.

As of 7 PM on October 2, 2021, the Xinjiang Yihua gasification unit, built by CAS Hefei Coal Gasification Technology Co., Ltd. (“ZHGAS”), reached 200 days of continuous, safe operation on a single circulating fluidized bed (CFB) gasifier, setting a new record for continuous operation using high-alkali coal as feedstock.

At 11:00 PM on September 22, the Shandong Bluesail fixed-bed gasification indirect cooling upgrade project, undertaken by ZHGAS, was successfully commissioned. This marks ZHGAS's solid first step into the butanol and octanol industry. Furthermore, this project is the first fixed-bed indirect cooling renovation project in China's butanol/octanol sector.

Recently, ZHGAS signed a fixed bed clean coal gasification environmental protection and energy-saving retrofit project with Jiangsu Heyou Chemical Co., Ltd. (hereinafter referred to as "Jiangsu Heyou"), for the upgrade of its crude coal gas cooling and dust removal process.

At 7:00 AM on January 23rd, the No. 1 furnace of the Xiamen XiangSheng Circulating Fluidized Bed Oxygen-Enriched Coal Gasification Project, undertaken by ZHGAS, successfully passed its 168-hour performance assessment. This marks a significant breakthrough in the efficient utilization of Indonesian lignite using Circulating Fluidized Bed Coal Gasification (CGAS) technology, further validating its coal adaptability.

On the first day of 2021, 14 engineering and design personnel from the indirect cooling upgrade project teams for Jinmei Tianyuan, Shanxi Jinxiang, and Shanxi Jinfeng fixed-bed gasification, under ZHGAS, spent the day at their respective project sites. They were unable to return home to reunite with their families during this holiday and spent the New Year amidst intense and orderly work.
