The design of the stripping tower
of Aromatics extraction unit
Abstract: The tower is widely used in critical production equipment of the chemical, oil and other industries. The main subject of the aromatics extraction unit designed stripping tower. Hydrocarbon extraction unit is a use of the principle of extractive distillation to pyrolysis gasoline hydrogenation of aromatics-rich and redepentanizer oil as raw material, using sulfolane as solvent, liquid-liquid extraction, the use of liquid-liquid extraction and pumping mention a hydrocarbon mixture, distilling aromatic and non-aromatic hydrocarbons separated to obtain benzene, toluene, o-xylene, mixed xylene, etc. of the device. The main subject of the design according to the given conditions of the stripping tower structure design, material selection, strength and stability calculations, component design choice for davit lifting lugs, trays, equipment, flange, platforms and escalators a plate tower components such design choices. Finally, the finite element software for finite element analysis of the distillation column, distillation test loads in the wind meets the strength requirements.
Keywords: aromatics extraction unit; plate tower; finite element; stripping tower
