Erection of the synthesis tower for the second phase of the ammonia synthesis capacity expansion project at Guangxi Hengyi New Materials completed

Thread Content

Recently, the synthesis tower, a key piece of equipment for the second phase of the expansion of ammonia synthesis capacity in the 1.2 million-ton per year caprolactam–polyamide integrated production project carried out by the Southwest Branch of Sinochem Second Construction Group for Guangxi Hengyi New Materials Co., Ltd., was lifted into place successfully. It is reported that the synthesis tower has a net weight of 188 tons, a diameter of 2 meters, and a height of 22 meters; both its height and weight make it the largest piece of equipment in this facility. Faced with challenges such as the large operating radius of the cranes and irregular lifting points for the equipment, the project team conducted multiple on-site surveys of potential crane locations, planned carefully to overcome constraints related to the limited working area, and adopted a solution involving a 900-t truck crane as the main lifting device along with a 500-t crane for assisting with the lifting process. As a result, the equipment was successfully placed on the equipment foundation at the 8.7-m level.
