en.Wedoany.com Reported - A critical milestone was achieved on April 3rd in the energy-saving and environmental protection upgrading project of Shanxi Lanhua Coal Chemical Co., Ltd. in China, with the precise and smooth positioning of the ammonia synthesis reactor shell (R630001) in the ammonia synthesis unit area. This equipment measures 2.8 meters in diameter, 31 meters in height, and weighs 407 tons. Prior to this, on March 29th, the project's final Saiding gasifier was accurately positioned, marking the completion of the installation of all five Saiding gasifiers and ushering the project into a new phase of construction.
The newly installed Saiding gasifier is the JM-S new model developed by Saiding Engineering Co., Ltd. specifically for Jincheng anthracite fine coal. It boasts advantages such as wide feedstock adaptability, high methane content, high thermal efficiency, and low oxygen consumption. Equipment parameters indicate a single unit length of 14.5 meters, an inner shell diameter of 4 meters, a wall thickness of 60 millimeters, a weight of 152 tons, a design pressure of 4.6 MPa, and a daily coal feed capacity exceeding 600 tons per unit. The project adopts a "4 operating, 1 standby" configuration. These five new gasifiers will completely replace the 37 atmospheric fixed-bed intermittent gasifiers currently in use at three existing enterprises in the Lanhua Bagong area.
The technological upgrade will significantly enhance energy efficiency and environmental performance. Combined with Co-Mo series sulfur-tolerant shift catalysts and Casale low-pressure ammonia synthesis technology, the project is expected to increase raw coal utilization by over 15% and achieve a carbon conversion rate exceeding 99%. This signifies the complete retirement of the atmospheric fixed-bed intermittent gasifiers that have been in operation at Lanhua for over two decades, leading to a substantial reduction in waste emissions and energy consumption.
Through this energy-saving and environmental protection upgrading initiative, Shanxi Lanhua Coal Chemical Co., Ltd. is accelerating its transformation towards "cleanliness, scale, intensification, and intelligence." The project's implementation not only strengthens the company's competitiveness in the coal chemical sector but also provides a model for the green and low-carbon development of the regional chemical industry. With all core equipment now in place, subsequent installation and commissioning work will commence in full swing.
