    Metal tower structured and random packing key internals of packed tower

    Metal tower structured and random packing key internals of packed tower
    Structured packing is a kind of packing arranged and stacked in accordance with uniform geometry in the tower. The geometry of the whole tower section is regular, symmetrical and uniform, and the gas-liquid flow path is specified, which reduces the phenomenon of channel flow and wall flow, and the pressure drop can be very small. Under the same energy cost and pressure drop, it can provide more specific surface area than random packing, and achieve higher mass transfer and heat transfer efficiency in the same volume. At the same time, due to the uniformity, regularity and symmetry of its structure, when it has the same specific surface area as random packing, its void ratio and flux is larger, and its comprehensive processing capacity is much larger than tray tower and random packing tower. After careful design, manufacture, installation and operation of tower internals (such as gas-liquid distributor), the industrial amplification effect is not obvious. In recent decades, structured packing has been widely used in many towers in fine chemical industry, perfume industry, oil refining, fertilizer, petrochemical industry and other fields.
    Our company mainly produces and supplies two kinds of metal structured packing, corrugated orifice plate structured packing and wire mesh structured packing.

    Corrugated plate structured packing has the advantages of large flux, small resistance, high efficiency, low cost and strong anti plugging ability. 250Y type corrugated packing is the first one developed and applied in industrial production, which reflects the excellent performance of corrugated packing. It has good separation ability and wide operation range. It can replace the general tower and revamp the old tower to extend the service life. 250Y type packing is widely used in many towers of chemical industry, oil refining, gas purification and other industries (such as ethylbenzene, styrene, aromatics, tall oil, methanol, ethanol, quench tower, atmospheric and vacuum distillation tower, natural gas drying, carbon dioxide and hydrogen sulfide absorption and analysis tower, ethylene oxide absorption and analysis tower, acrylonitrile absorption tower, etc.).

    Wire mesh structured packing has a high specific surface area, at the same time, because of the unique capillary effect of the mesh, the packing surface has better wettability, so it has a high separation efficiency. Compared with other types of packing, it has lower pressure drop and less liquid holding, and is especially suitable for materials hard to separate and heat sensitive systems. The main materials for making wire gauze packing are stainless steel, copper, aluminum, iron, nickel, etc. According to the specific surface area, the wire mesh packing can be divided into 250 type, 500 type and 700 type. Because the wire mesh packing belongs to the type of liquid film mass transfer, the key to maintain high separation efficiency is to make holes in the corrugated packing sheet or to make a double-layer wire mesh packing to strengthen the uniform distribution of liquid on the wire mesh corrugated sheet, especially when the spray density is low.

    Note:
    1. The data are based on 0.12mm wire, stainless steel material. Applicable temperature (-200—400)℃. 0.15mm and 0.17mm wire are also available.
    2. Metal wire mesh corrugated packing is suitable for clean gas-liquid system without solid particles or suspended solids or not easy to self-assemble.
