Application of wire mesh corrugated packing in fatty acid methyl ester distillation tower

1、 Project Overview and Customer Requirements

• ProductFatty acid methyl ester (an important fine chemical raw material commonly used in the production of surfactants, biodiesel, etc.)

• Core equipment:DN1500 Distillation Tower

• Process parameters:

• Core requirements:Efficient and high-purity separation of fatty acid methyl esters requires fillers to haveHigh separation efficiency, low pressure drop, and significant operational flexibility.

2、 Recommended solution: Metal wire mesh corrugated packing

Our company strongly recommends the use of fatty acid methyl esters due to their thermal sensitivity and requirements for product purityMetal wire mesh corrugated packingThis filler is the first in the field of precision distillation, especially suitable for vacuum distillation of high boiling point, thermosensitive systems such as fatty acid methyl esters.

Product Structure Features:

• After being pressed into corrugated sheets from metal wire mesh of specific materials, they are arranged and assembled into a disc in sequence.

• Ripple inclination angle:(Commonly used at 45 °, balancing efficiency and flux).

• Assembly method:The two disks of packing are vertically rotated 90 ° and stacked in a staggered manner, forming a complex network channel that greatly promotes the lateral mixing and surface renewal of gas-liquid phases.

Core advantages:

1. Mass transfer efficiencyThe huge specific surface area and excellent liquid distribution ability of the wire mesh provide a massive number of mass transfer points for gas-liquid contact. The theoretical number of plates can reach several to more than ten per meter, making it easy to achieve high-purity separation.

2. Extremely low pressure dropA regular perforated channel ensures unobstructed airflow, significantly reducing tower kettle temperature and energy consumption. It is crucial for the separation of thermosensitive materials such as fatty acid methyl esters, effectively preventing decomposition and coking.

3. Small liquid holding capacity, high operational flexibilityFast start-up, quick response to operating conditions adjustment, and able to adapt well to fluctuations in production load.

3、 Selection suggestions for this project

For a DN1500 tower diameter and a production capacity of 6 tons/hour, with a body fluid flow rate of 7 tons/hour, we recommend:

• Recommended model: BX500 typeOrCY700 typeStainless steel wire mesh corrugated packing.

• BX500 type: With itsHigh separation efficiencyKnown as a classic choice for precision distillation, it ensures the purity of the product.

• CY700 typeWhile ensuring high efficiency,Greater fluxWith wider operational flexibility, it can better adapt to potential demand for increased production.

• Material selection:Considering the low corrosiveness of fatty acid methyl esters, it is recommended to useS304 stainless steelIf the material contains trace amounts of chloride ions or has special requirements for the product, it can be upgraded toS316LTo enhance corrosion resistance.
