Abstract:

Half-open pipe is commonly used at the inlet of separators, and its structure and layout have a vital impact on the separation effect. In order to study the influence of half-open pipe layout on gas-liquid separation, this paper takes the separator of a domestic offshore platform as the research object, and uses numerical simulation software to simulate and analyze the half-open pipe models at different installation positions. The influence of different installation positions of half-open pipes on gas-liquid pre-separation effect is obtained, and some suggestions are put forward for the layout design of half-open pipes at the inlet of separators, providing theoretical support for the optimal design of separators.
