On December 1, the core equipment of the Hunan Petrochemical Biomass Gasification Flexible Platform project, the fluidized bed gasifier, was successfully lifted into place. It is reported that the equipment is 28.41 meters in length and weighs 150 tons; the gasifier and the cyclone separator are connected together and lifted as a single unit. The cyclone separator’s cylinder wall is only 20 millimeters thick, and it contains a brittle fire-resistant lining material inside. Calculations show that with the traditional method of using one crane to lift the equipment and another crane to handle the tail end, the displacement and deformation caused by the equipment itself during the process of lifting it from a horizontal position to an upright one will reach 121 mm, which will result in the lining material coming off. To ensure a successful lift, experts from Sinopec’s headquarters, Hunan Petrochemical Engineering Department, Ningbo Company, and Baling Supervision Company conducted thorough calculations and analyses. As a result, it was decided to deviate from the conventional method of using two cranes for lifting; instead, a \"three-crane lifting\" approach was adopted within a 30-meter range: one 1,250-ton crawler crane was used as the main crane, another 260-ton crawler crane served as a helper crane, and an 80-ton truck crane was used for lifting in the middle, thereby reducing deformation of the cyclone separator.
