ABSTRACT

Knocked down assembly or segmentation hoisting is generally used for flare stack with flange connection structure. This paper presents a novel technology of integral hoisting of flare stack with flange connection structure. In the paper, CATIA finite-element-analysis is used to build the model of flare stack and to simulate working condition in both horizontal and vertical limit states during integral hoisting of flare stack. The strength and stability of flare stack during hoisting is checked and calculated. The dangerous points and weak structures are conducted through the reinforcement treatment to provide evidence for hoisting procedure design and formulation of hoisting plan.
