250Y metal orifice plate corrugated packing has a large surface area and high efficiency

250Y metal orifice plate corrugated packing is a mainstream high-efficiency structured packing for distillation, absorption, and extraction units in industries such as petrochemicals, coal chemicals, and fine chemicals; The "250" in the model represents a standard specific surface area of 250m ²/m ³，Y "is a universal orifice plate corrugated structure, 250Y metal orifice plate corrugated packing has a large surface area and high efficiencyThe comprehensive advantages of low pressure drop, anti blocking and durability make it an ideal choice for balancing separation efficiency and operational stability.

1、 Precision Structure and Materials

Structural Design: Adopting0.15-0.20mm high-quality metal sheet (mainly made of 304/316L stainless steel, can be customized with duplex steel and titanium materials), made by precision stamping, punching and rolling corrugations; The crest angle of the ripple is about 90 °，Channel inclination angle30/45 ° alternation, adjacent flow channels form a 90 ° angle，Rotation of upper and lower platesStacking at 90 ° to form uniformly staggered mass transfer channels; The opening rate is 9-12%, and the small holes have both liquid redistribution and boundary layer disturbance effects, enhancing gas-liquid contact.

2、 Core advantages

High aspect ratio meterarea+Efficient mass transfer: The specific surface area of 250m ²/m ³ is much higher than that of 125Y (125 m ²/m ³), and 2-3 theoretical plates can be provided per meter of packing. The separation efficiency is 2-3 times that of traditional bulk packing (Ball ring, Rascal ring); Can reduce tower height, shrink equipment size, and lower infrastructure and land occupation costs; Under vacuum/atmospheric distillation conditions, the gas-liquid contact is uniform, without channeling or wall flow, and the separation purity is significantly improved.

Flux and pressure drop balance:97% high porosity ensures high throughput, with an F-factor of 2.6, suitable for medium to large processing volumes; The pressure drop is only 1.5-2 × 10 ⁻⁴ MPa/m, far lower than high specific meter models (such as 350Y, 500Y), energy-saving and consumption reducing, especially suitable for vacuum systems and long-term operating devices.

Strong resistance to blockage、High durability: Compared to wire mesh corrugated packing, the orifice plate structure is less prone to clogging and can withstand complex materials containing trace amounts of solids, high boiling points, and easy coking; Metal material has high mechanical strength, acid and alkali corrosion resistance, long-term operation without deformation or detachment, long maintenance cycle, and low shutdown cost.

Flexible customization、Easy to install: can be customized as a whole or block structure according to the tower diameter, suitable for flange connection towers and large-diameter manhole installation towers; Standardized module design, fast on-site assembly, and shortened project duration.

3、 Typical application scenarios

Petrochemical industry: atmospheric and vacuum distillation tower, aromatic distillation tower, ethylene/Acrylic absorption desorption tower;

Coal chemical industry: methanol distillation tower, synthesis gas purification tower, coal tar separation tower;

Fine chemical industry: solvent recovery, organic acid/Alcohol separation and fragrance purification;

Dehydration, desulfurization, and carbon dioxide recovery.

4、 Selection and Service Tips

250Y metal orifice plate corrugated packing has a large surface area and high efficiencyPriority is given to operating conditions that require separation efficiency, processing capacity, and pressure drop; When containing a large amount of impurities, it is recommended to use an efficient liquid distributor;The material should be determined based on the corrosiveness of the medium, temperature and pressure conditions (such as strong corrosion selection)316L、 Titanium material);We can provide one-stop services for packing design, tower internals matching, and installation guidance to ensure that the packing performance is fully utilized.
