On January 8, good news came from the construction site of the Hebei HNA Petrochemical project, whose annual production capacity is 800,000 tons of butyl octanol, and which is being built by the Fourth Engineering Company of China National Chemical 14th Construction Corporation. The lower section of the H2S concentration tower, one of the tower equipment components, was successfully lifted into place with precision, marking the full entry of the project construction into the critical phase of equipment installation. It is reported that the lower section of the H2S concentration tower being lifted this time is a core piece of equipment for the project, making the lifting process difficult and requiring high technical expertise. The tower section is 35.6 meters long, with a total lifting weight of around 140 tons; it needs to be lifted over an existing frame structure, and the maximum lifting height reaches 70 meters. To ensure the safe and efficient completion of the lifting operation, the project team evaluated various plans on multiple occasions; ultimately, a collaborative approach was adopted, using a 750-ton crawler crane as the main lifting device and a 500-ton truck crane as an auxiliary one, thereby ensuring adequate safety margins for the lifting process.
