The tower is filled properly high filler, with a two increase in fluid contact between the surface. The structure is simple, maintenance is convenient. Widely used in gas absorption, distillation, extraction and other operations. Separation of distillation is the most commonly used liquid mixture of a unit operation, in oil refining, chemical, petrochemical and other widely used in industry. Distillation process in energy agent drive (sometimes combined with quality agent ), the gas-liquid two-phase multiple direct contact and separation, using liquid mixture of the components of the volatility, the volatile components from liquid to gas transfer, difficult volatile components from gas to liquid transfer, realize raw material mixture component separation. In chemical or oil refinery, tower equipment performance to the quality of production, production capacity and consumption rated and waste treatment and environmental protection and other aspects have great influence. According to concerning data report tower equipment information costs accounted for the larger proportion of investment costs. Therefore, the tower equipment design and research, by the chemical industry and oil refining industry seriously. According to the design task book, the tower is designed to be packed distillation column. Key words: benzene, toluene, packed column, liquid mix
