Tray towers and floating valve towers

Different tray types are selected based on various media and operating conditions. When comparing the two types of trays, floating valve trays are more efficient. However, at high gas phase line speeds, the floating valves can be easily displaced, and their cost is also higher compared to tray trays with sieve plates ； The sieve tray has a simple structure, but its separation efficiency and operational flexibility appear to be lower than those of the floating valve tray; moreover, it is prone to coking that blocks the sieve pores ； These days, a long service life is important; if the equipment can handle a steady volume of material, the medium is clean and not prone to coking, it is recommended to use either of the aforementioned types of sieve trays. They have low costs, a low failure rate, and a long service life – they can be serviced every 3 years or even every 6 years without any problem.
