What does structured packing 700Y mean

Structured packing 700Y is a kind of structured corrugated packing widely used in chemical industry, environmental protection, petroleum and other fields, the "700" in its name usually represents the specific surface area or model specifications of the filler, and "Y" indicates that the corrugated inclination is **45°** (corresponding to Y structure). The following is its specific analysis:

1. Structure and material

Corrugated design: A disk structure composed of parallel, crossed and vertically arranged corrugated plates, with a corrugated Angle of 45° (Y-type), and two adjacent plates of packing staggered 90° to optimize gas-liquid contact.

Material diversity:

Ceramic material: strong corrosion resistance, suitable for strong acid, strong alkali environment (such as desulfurization, wastewater treatment).

Polypropylene (PP) material: anti-aging, temperature resistance (≤90℃), commonly used in flue gas desulfurization, oil-water separation.

Stainless steel (e.g. 304/316L) : high temperature and pressure resistance, suitable for gasoline fractionator and other harsh conditions.

2. Performance characteristics

High mass transfer efficiency: The corrugated structure increases the contact area of atmospheric liquid and improves the separation efficiency, especially for difficult to separate systems.

Low pressure drop: Orifice design (e.g. corrugated metal orifice plate) reduces fluid resistance and is suitable for large liquid load scenarios.

Plugging resistance: The hole plate or piercing structure enhances the fouling resistance and prolongs the service life.

Corrosion resistance: Ceramic and metal materials can withstand acid and alkali, high temperature and high pressure environment.

3. Application field

Chemical and environmental protection: used for absorption, rectification, desulfurization and denitrification, waste gas purification and other processes.

Petroleum and energy: gasoline fractionator, oil-water separation, oilfield wastewater treatment.

Pharmaceutical and metallurgical: gas-liquid separation in pharmaceutical synthesis, extraction, metallurgy.

4. Model and customization

Type classification: According to the specific surface area and corrugation Angle is divided into different specifications (such as 125Y, 250Y, 700Y), the larger the number, the larger the specific surface area, the higher the separation efficiency.

Customization: The size and material can be customized according to the tower diameter and working conditions, such as polypropylene material support Enhanced (RPP) or high temperature resistant (PVDF).

Summary: Hengerwo Chemical's 700Y structured packing balances mass transfer efficiency and pressure drop through a 45° corrugated Angle and staggered design, and its material diversity makes it an efficient separation solution for chemical, environmental and other fields.
