Nozzles, Laterals & Resin Traps are basically filtration/retention components used in Ion-Exchange Columns. The main purpose of the nozzles and laterals is to keep the resins inside the column while allowing only the fluid to pass through. In case there is some leakage from the column then the resin traps are used as safety traps in the pipe lines just after the column. Owing to continuous operation of columns high reliability is expected from these components as any leak of resins will lead to untimely shut-down of the units causing heavy losses and high maintenance costs of downstream equipment. With apt design expertise the nozzles and laterals can be designed to avoid channelling effect and dead- zones in media bed.
The laterals are generally provided with a central hub or a header for collection or distribution of the fluid over the media bed. This system allows for maximum utilization of vessel volume for filling it with the media as even the dish-end portion can be utilized. APT can provide customized solution to suit the dish end contour of the vessel using hub & spoke type design or it can be simple straight header design, horizontal or vertical, depending on the application and client requirement.
Due to continuous slot opening of the screen, it provides excellent distribution and collection without wall effects and channelling. Each Lateral can be mounted on perforated pipes in order to optimize both mechanical resistance as well as collection efficiency with calibrated holes. Depending on the application the Laterals can be supplied in SS304/304L/316/316L, Hastelloy C276, Duplex, Super Duplex, etc.
