ABSTRACT
Light hydrocarbon refined and purification technology is an important component of the petroleum chemical industry. The research of light hydrocarbon refined and comprehensive utilization is important to improve added-value of light hydrocarbon fractionation products, the actual application of distillation theory, and the refining of saturate hydrocarbon products and the light hydrocarbon fractionation product processing. Light hydrocarbon is a mixture of low-carbon saturated hydrocarbon which has respective quality and use, Special purity is required for different uses of the product, which makes light hydrocarbon refined and comprehensive utilization become a complex process which involves in various petrochemical industry fields.
The design of the main production process for the separation of light hydrocarbon section in the calculation. Suit lignt hydrocarbon fictions from oil refnery were selected, the rational separation sequence was optimized according the demand for raw materials，composition and the product target. By calculating the required number of theoretical plates, reflux ratio, the tower operating pressure, operating temperature, product flow rate, high tower, tower diameter calculations, it calculate tower on the plate using the F-type floating valve tray and a tray of checking hydraulics calculation.
