The Design of Xylene Cooler
Abstract:This article describes the design of the overall structure of xylene cooler. There is only one tube sheet in a floating head type heat exchanger. Both ends of the tube are fixed on the same tube sheet. The tube can be freely retractable, no thermal stress and has good thermal compensation. The tube process flow is relatively long, it has relatively high flow rate and better heat transfer performance, and can take strong pressure. Bundle can be withdrawn from the housing in order to maintenance and cleaning easily. Its structure is simple, and the cost is cheap. The main structure of the floating head heat exchanger including tube box, cylinder, head, heat transfer tubes, tools, baffled，anti drawing board and draft tube, the structure of the short-circuit proof, supports and other accessories.
The design temperature and design pressure are little high so that the demand need to be higher. It is used the choice of material, structural design, strength design and selection of parts in the design of the xylene cooler.
