| Abstract: | CJST-Trays are successfully applied in expanding production transform of industrial naphthalene rectification column.Under the condition that the tray spacing is 300 mm,float trays are replaced by CJST-Trays.After transform,the treatment capacity increases 50%;naphthalene content in wash oil at column bottom decreases from 15% to 5%;temperature at column bottom increases from 271.5℃ to 275℃;pressure drop of column reduces 5 kPa.The results show that the system is running well.The problem of expanding production is solved,and the economic benefit of more than 6 million yuan is obtained for the corporation each year. |
