Progress on the Construction of the Synthetic Ammonia Raw Material Route and Energy-Saving/Emission-Reduction Technology Upgrade Project at Zhejiang Juhua Jinju Co., Ltd. Author/Source: Thirteenth Chemical Engineering Construction Company Date: 2022-03-03 Clicks: 13 On February 25, the gas scrubber, one of the large-scale equipment involved in this project, was successfully installed, marking the official start of the installation work for such large-scale equipment on this project. The gas scrubber is 23.73 meters tall, 3 meters in diameter, and has a net weight of 107.43 tons. The project team uses a single-crane lifting and delivery method, with a 650-ton crawler crane as the main crane and a 350-ton truck crane acting as a trailing crane. At 15:30, as the boom of the main crane moved slowly, with all construction workers working in close coordination, it took only 28 minutes to properly position the gas scrubber tower. The synthetic ammonia feedstock route and energy-saving and emission-reduction technology renovation project of Zhejiang Jinju Chemical Co., Ltd. adopts 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 total gas volume is 94,000 Nm3/h (CO + H2). The water-cooled wall direct-connected waste-heat gasifier for coal-water slurry (Jinhua Furnace 3.0) replaces the existing batch fixed-bed gasifiers and low-pressure refractory brick quenched gasifiers.
