Another milestone has been reached in the technical renovation project for air separation capacity of 39,000 Nm3 at Zhejiang Jinju Chemical Co., Ltd., which utilizes Jinhua Furnace 3.0. Author/Source: Gasification World Date: February 9, 2021 Clicks: 29 On February 8, with the installation of the last heat exchanger completed, the installation work for the compressors as part of the synthetic ammonia production line and energy-saving/emission-reduction technology renovation project at Zhejiang Jinju Chemical Co., Ltd., which was overseen by Donghua Technology, was successfully finished. A 500-ton tower crane with tracks was used for this lifting operation, which enabled the lifting of 13 pieces of equipment and their accessories in total: 2 compressors, 1 turbine, 1 oil station, and 9 heat exchangers. The compression unit is the core equipment of air separation plants; its installation is difficult and requires high technical expertise. The completion of the lifting work for the compression unit represents a milestone in the Jinju air separation project. It lays the foundation for the installation of the compressors, which is a key step in the entire project, thereby creating favorable conditions for the timely completion of the project. The synthetic ammonia feedstock route and energy-saving and emission-reduction technology renovation project of Zhejiang Jinju Chemical Industry utilize the water-cooled wall waste boiler gasifier (Jinhua Furnace 3.0) technology developed by Beijing Qingchuang Jinhua Technology Co., Ltd. The gasification unit is designed as a dual-unit setup without a backup unit; the gasification pressure is 6.5 MPaG, and the volume of syngas produced is 94,000 Nm3/h (CO + H2). The water-cooled wall direct-connected waste boiler gasifier (Jinhua Furnace 3.0) for coal water slurry replaces the existing batch fixed-bed gasifiers and low-pressure refractory brick quenched gasifiers. Production is scheduled to begin in 2021. On December 10, the model review was completed for the technical renovation project of Jinju Chemical’s 39,000 Nm3 air separation unit, which utilizes Jinhua Furnace 3.0. On November 7, the two molecular sieve adsorbers, which are part of the large-scale equipment for Zhejiang Jinju’s 39,000 Nm3 air separation project, were successfully installed. On November 3, the construction of the main cooling tank was completed, and on November 1, the air cooling towers and water cooling towers were successfully installed as well.
