【Abstract】 This article establishes a mathematical model for crude benzene rectification by use of rectification principle on the basis of vapor liquid balance. Besides, it makes analog computation for the model by use of triple diagonal matrix method, Gaussian elimination method and pursuit method. Result proves that this model is reliable and universal. This model will provide a quantative basis for the design or operating scheme determination of rectification tower.更多还原
