Valve Tray VE TRAYS which usually have a cost comparable to perforated trays, afford the widest operating ranges and greatest capacity. Considering the additional operating range and capacity of valve trays over perforated trays, it can be concluded that valve trays are actually lower on cost. In many applications, vapor loading controls capacity. In many…
Plate Mist Eliminator A plate type mist eliminator is also called a chevron mist eliminator, a vane type mist eliminator, etc. It collects liquid droplets entrained in the gas by means of inertia impaction. No plugging occurs when it separates and eliminates plenty of dust or viscous mist from the liquid droplets, so excellent collection…
Support Plate A support plate has a function to physically support the weight of the packing, and free areas should be designed to have vapor and liquid evenly distributed. The common types of support plates are the gas injection type used for random packing, and the support grid type used for structured packing.
Bed Limiter A bed limiter is used to prevent the packing from moving or breaking away from the bed by severe gas flux caused during operation after the inside of the tower is filled with packing. The common types of bed limiters are the mesh type used for random packing, and the plate type used…
Distributor A distributor, installed at the upper part of the bed, does the job that the liquid should be distributed evenly over the bed. There are three types of distributors, namely the gravity type, the flashing type, and the spray type. Theoretically, a spray type distributor can lead to more even distribution, but some problems…
Feed Device A liquid feed pipe is a device for feeding liquid to a distributor or redistributor. Each feed area is used to lower the rate of liquid flow incoming from the feed pipe, to prevent an excessive unstable liquid flow inside the dis- tributor, and to maintain horizontal liquid flow. Generally, this pipe is…
Structured Packings Structured packing was developed in the early 1940’s, but failed to be popular because of liquid maldistribution and a lack of sufficient markets. Afterwards, corrugated sheet type structured packing was developed in the late 1970’s, and now it is widely used. Structured packing costs high and makes maintenance difficult. Especially, the drawback is…
High Performance Tray A high performance valve tray, most recently developed, can increase its capacity up to 60 % or more compared with existing trays. It is also a slightly improved type in terms of efficiency. Our feature products are NHP valve trays which have higher process capacity and lower pressure loss than conventional trays…
Valve Tray A valve tray was developed to improve a drawback that a sieve tray has a narrow operating range. Different types and characteristics of valve trays are made by different companies. Common valve trays are circular, but sometimes square valve trays are also used. According to use, standard valves, caged valves, and venturi valves…
Sieve Tray A sieve tray is a low-cost type of tray by which a bubble cap tray is replaced. It has been used as separation equipment for a long time since it was developed in the early 1950’s. If it is properly designed, it gets abreast of any other tray in efficiency and capacity. In…
