Description

After being used by Qinhuangdao and Changzhou Gas Plant, Weihai Gas Plant, Chuanwei Iron and Steel Company and Wusong Gas Plant for naphthalene washing or ammonia washing, the product has been proved as having the following features: A. Multi-pore packing has a light specific gravity and low obstruction. The density of multi-pore packing is 1.*4g/cm3 and the specific gravity of one pile is 0.4g/cm3, which is much lower than for ceramic and metal packing. Thus it has the advantage of being light weight. Changzhou Gas Plant used this product in ***2 and it was still in good condition in ***9, without having any problems. This saved the factory a lot of money on the cost of replacing packing. Multi-pore packing has a large mass-transfer co-efficient, large valid area and excellent effectiveness. Tests conducted by Tianjin University have shown that the coefficient of multi-pore packing is 2.2 times higher than holo-ceramic packing. When packed, multi-pore packing overlaps with neighboring packing by six supporting legs, thereby constructing a void area. Gas and liquids are transferred over the parting plane. Multi-pore packing has many honeycomb-like microscopic pores that extend the available specific to *9.5%. Although there are other types of packing available, they are less efficient. This product is most effective when used in separation. Multi-pore packing can resist aging, sudden heat and sudden coldness. Its fire-proofing rate is ***0oc , and it is acid resistant, thus can be used for a long time and is not easily aged. A gas plant in Hefei has applied multi-pore packing since***1, and until now has not required changing. Compared with multi-pore ceramic packing, plastic packaging costs less, but plastic ages easily and can&#**9;t resist high temperatures. Carbon steel packaging can&#**9;t be used in conditions that have corrosive media, and stainless metal packing has a higher cost. Multi-pore packing has a new structure that can make circular shapes, is able to be cut and easy to pack. Also, **0% of the packing plane can be used. Some other kinds of packing can&#**9;t be cut, so it is inevitable that there are holes around the inner part of the tower, and it&#**9;s possible that wall flow and channeling occur. The success of using such materials will be affected to different extents. Multi-pore packing successfully eases the contradiction between air gap rate and specific area, it doesn&#**9;t cause tower blockages and is very efficient, so it&#**9;s the best choice of those people who want to purchase packing tower
