1、 Product introduction

452YPlus corrugated packing is a low-pressure drop, higher flux of the regular packing, specific surface area of 452m2/m3, void ratio of 93%, each theoretical plate pressure drop than the conventional stainless steel orifice plate corrugated regular packing is reduced by 30-50%, the amount of liquid holding capacity of about 8-15% of the volume of the packing. Its anti-pollution because the free cross-section is larger, flow film is more uniform, so it is not more than other filler by pollution. Slight surface adhesion generally does not affect the efficiency. Liquid load up to 0.2m3/(m2.h), its amplification effect is not obvious.

452yplus aperture plate corrugated packing appropriate to increase the aperture rate, so that the metal plate corrugated area on both sides of the wetting, vapor-liquid contact exchange is more adequate, ** to improve the utilization of the filler surface area, and thus has a high mass transfer efficiency; filler straight edge corrugated and tilted corrugated alternating combination of structures, strengthen the degree of vapor-liquid two-phase perturbation to increase the impetus to improve the mass transfer, reduce the resistance to mass transfer, so that the two neighboring The vapor-liquid phase flow path between the two adjacent packing layers is more open, reducing the circulation resistance of the vapor-liquid two-phase drop, so it has the advantages of high flux and low pressure drop. Further improve the processing capacity and mass transfer efficiency. Therefore, the resistance is greatly reduced, applicable to the transformation of the regular packing tower occasions. But ordinary stainless steel orifice plate corrugated packing is not suitable for processing viscosity, easy to polymerize or suspended materials, cleaning is also more difficult.

2、 Product Comparison

452Yplus regular packing and conventional ordinary 450Y orifice plate corrugated packing compared to the difference lies in 452yplus orifice plate corrugated packing more than a straight edge, and it is this structure above the change, making the new plus regular packing 452yplus orifice plate corrugated packing in the performance of the above than the ordinary conventional stainless steel orifice plate corrugated packing, increase the processing capacity, reduce the pressure drop, and so on. This is why more users are now choosing the new plus regular packing orifice plate corrugated packing.

3、Application

452YPlus corrugated packing and other series of PLUS regular packing: the products are mainly used in oil field oil and gas treatment, three-phase separator agglomerates, petrochemical industry, such as lubricating oil type pressure reducing tower, fuel oil type pressure reducing tower.

(1) Mainly solve the bottleneck effect of the regular packing tower: in the same diameter of the regular packing tower, when a certain section of the filling production of the flooding point percentage is high, Plus corrugated packing can be used instead of conventional corrugated regular packing;

(2) Improve the vacuum at the bottom of the decompression tower: Improve the vacuum at the bottom of the decompression tower can improve the extraction rate of the decompression tower, reduce the polymerization of the materials at the bottom of the tower, reduce the temperature of the decompression furnace or the reboiler, etc., so the use of low-pressure drop packing and low-pressure drop of the whole tower parts is imperative;

(3) energy saving, efficiency: when the atmospheric or pressurized tower behind the compressor, the use of low-pressure drop packing can reduce the tower pressure drop, so that the top operating pressure is slightly higher than the design value, which can reduce the compressor’s compression ratio, to achieve energy saving. If the operating pressure at the top of the tower remains unchanged, the lowering of the pressure at the bottom of the tower can improve the extraction rate of the components, realizing efficiency gains.
