Abstract:

Ethylene rectifying column is used to separate ethylene product, and its control directly affects the quality and yield of ethylene product. Aspen Plus simulation software was used to analyze the ethylene rectifying column of ethylene plant. The positions of feed tray and sensitive plate in ethylene rectifying column were determined, and the influences of process parameters on ethylene product specifications were obtained by sensitivity analysis. Guided by the simulation, the temperature control of sensitive plate and the level control of tower bottoms were installed, and the control of pressure and return flow in ethylene rectifying tower were optimized, thus increasing the output of ethylene, reducing the energy consumption and improving the overall economic benefit of the plant.
